5 Important Things To Do If Your Pet Has FLEAS

Hello, readers! So, if you’ve stuck around for the last week or two, you’ve been with me as we hammered the topic of fleas and flea prevention into dirt (flea dirt, to be exact).

Today, we’re going to wrap up with something short, sweet, and important! Many people (myself included) find themselves in a flea induced panic at least once in their life. Here is a quick guide to help you keep your head on straight so that you can help your pets and get rid of your fleas ASAP.

If you notice that your pet has fleas, you should:

  1. Don’t panic. Take a deep breath, then proceed to step two.
  2. Get some flea prevention. Call your vet. If you’ve been to the vet within the last 6-12 months, they should be able to get you some effective flea prevention that starts working within hours. As a reminder, I recommend these products for dogs and cats. I do NOT recommend these products.
  3. Treat Your Environment. Remember that a large portion of a flea problem is actually in your environment- your yard, your carpet, your furniture. Call an exterminator for the best recommendations on how to treat your home in a way that is safe for your family and also effective. If you can’t hire an exterminator, make sure you follow the instructions on over-the-counter pesticide product labels carefully. Wash your bedding, steam clean your carpet and furniture, and vacuum frequently.
  4. Keep using flea prevention for at least 4 months… and then year round. It takes at least 4 months to get rid of an active flea infestation, as fleas in the environment may hatch, hop on your pet, and start the process all over again. After the infestation has resolved, I recommend year-round flea prevention for all pets. Why treat the problem again when you can simply prevent it?
  5. Watch Out for Flea Related Illnesses. Usually, these are fairly mild. Tapeworms are very common, and they are spread when an animal ingests a flea while licking/chewing. Tapeworms can be easily identified when an owner sees small, rice-like worms around the pet’s rear end or on bedding. They can cause GI upset and, in severe cases, malnutrition. More serious illnesses, like bacterial infections spread by fleas, can also occur. If your pet is ill and has had fleas recently, make sure you tell your vet so that they can help diagnose the problem.

Thanks for reading! How have you dealt with flea infestations in the past? How long did it take to see an improvement in your pet and your environment?

My 5 LEAST Favorite Flea Preventatives for Dogs and Cats

Welcome back, everyone! We’ve talked about my favorite flea preventative products for dogs and cats, and discussed why flea prevention is important- even for indoor pets. Today, we’re going to talk about my 5 least favorite flea products (some of them shouldn’t even be called ‘preventatives’) on the market. I will attempt to stay off of my soap box and give factual information (based off of my knowledge of parasitology, pharmacology, and the flea life cycle), but some of this is anecdotally based.

Disclaimer: I have not been sponsored or paid to write about these products by anyone. These opinions are my own and are based of 2 years of experience as a veterinarian and a combined total of nearly 10 years of working in the veterinary medical field. My opinions do not necessarily represent the views of my employer or of the veterinary medical profession as a whole. I will not be liable for any errors, omissions, or delays in this information or for any losses, injuries, or damages arising from its use.

Now, here are my 5 LEAST Favorite Flea Preventatives for Dogs and Cats:

  1. Hartz

    I have two problems with the Hartz line of products. First, I don’t find them to be very effective. They will kill adult fleas, but do not keep killing the larvae and eggs. These stages live in the environment, will continue to hatch, and then will hop right back on your dog- starting the whole process over again. I believe that this lures pet owners into a false sense of security; I see many clients that think that they are doing everything that they need to for their pet, but in reality, they are wasting their time and money.

    My second problem with the Hartz line of products is that I see more adverse reactions with these products than with other flea medications. I don’t think that this is due to unsafe ingredients (the brand has full licensure by the EPA, which regulates all topical anti-parasitics), but it may be because people buy this product and do not get counseling from veterinary staff on how to properly use it. I also think that since these products are less effective and shorter acting, they may be applied too frequently, resulting in toxicity. Most of the complaints against these products is anecdotal, but I recommend that you spend your money on something else.

  2. Capstar (and other generic nitenpyram products)

    Overall, capstar is a good product. But it is not a good flea prevention- it is a good flea killer. I believe that this isn’t always clearly communicated to clients, and so they are lured into a false sense of security. Capstar is a tablet that is given and it kills all the active adult fleas on the dog or cat for 24 hours. That’s great, as long as you cover the rest of the month with something else.
    Remember, killing adult fleas for 24 hours is not going to stop your infestation- it will only set it back a little bit. In one of my first jobs at a veterinary clinic, an old man would bring in his 5 cats every month for capstars and a steroid injection (to treat the itching from the fleas). We could not persuade him away from this habit. Don’t be like him- Don’t waste your money every week and instead buy a monthly preventative.

  3. Flea/Tick Shampoos, Powders, or Sprays

    These products were once very popular methods of flea prevention, but they simply do not work. In order for them to have a chance of being effective, you would need to treat your entire home and bathe your pets every day. That would take a lot of time, money, and resources, and even then, your success isn’t likely. There are much easier, safer, and less messy ways to deal with parasites.

  4. Fipronil Products

    I almost didn’t put this one on the list, because I respect Frontline (Fipronil) as the flagship topical flea prevention for dogs and cats. However, now that Frontline’s patent is up, other generic fipronil products have come on the market. Let me be clear- out of this list, these products are probably the safest and the most likely to actually get rid of fleas. However, they don’t even compare to the line of newer products available through your vet.

  5. Essential Oils/Homeopathic Remedies

    If you want to see a veterinarian’s eyes turn red, tell them that you feed your pet garlic to prevent fleas. Not only does this not work, but garlic can cause hemolytic anemia (which can be fatal) in dogs and cats. I also have seen people using coconut oil, skin-so-soft, human shampoos, and essential oils on their pets. These products aren’t made to be used on pets, especially for this purpose. They won’t work, may damage your pet’s skin, and can be very harmful to your pet. Please don’t listen to the pet witch doctor you met online. Your vet really does know what’s best for your pet. If there was a cheaper and easier way to prevent fleas, we’d be all for it.

Question for readers: Have you used any products listed above? What was your experience?

My 5 Favorite Flea Preventions (For Cats)

Hi Y’all! Last weekend, I confessed my feline flea prevention faux pas. On Thursday, we talked about my 5 favorite flea preventions for dogs. Today, we’re going to give the cat people some love. Flea prevention is just as important for cats (even if they are indoor only) as it is for dogs. Cats often have fleas with few symptoms or signs- they are fastidious groomers and an owner may see their cat itch and be unsure why.  However, many flea products available on the market can be harmful or deadly to cats, and so it is important to know which products are best for your kitty.

Although this article will focus mainly on flea products, many of the products I list below are also heartworm preventatives. Heartworm disease in cats results in respiratory distress and can even be fatal. Your cat won’t need a heartworm test to get started on heartworm prevention, but it must be purchased from a vet or with a veterinarian’s prescription, so talk to your vet today about getting on flea and heartworm prevention.

Disclaimer: I have not been sponsored or paid to write about these products by anyone. These opinions are my own and are based of 2 years of experience as a veterinarian and a combined total of nearly 10 years of working in the veterinary medical field. My opinions do not necessarily represent the views of my employer or of the veterinary medical profession as a whole. To ensure complete transparency, products listed below that are followed by a star are sold in the veterinary practice where I work. Products that are italicized have been given to me as free samples by company representatives.

Please note that I only recommend products that are safe and effective. I would never recommend anything that I didn’t feel comfortable using on my own pets.

Now, without further ado, here are my 5 Favorite Flea Preventions For Cats

  1. Revolution* 
    Revolution is a very safe, gentle, and effective flea and heartworm preventative. It is applied topically on the back of the neck and lasts for a month. It also protects against ear mites, roundworms, and hookworms. I use this product frequently on my two cats. This is also the product I use on many small mammal species, such as ferrets, guinea pigs, and rabbits (although this is considered “off label” use).
  2. Advantage Multi
    This product is also a topical flea and heartworm prevention that protects against ear mites, roundworms, and hookworms. The biggest difference between this product and revolution is that Advantage Multi has been tested and is labeled for use on ferrets. This product is only available through your vet, but another product marketed by Bayer (and available over the counter) is Advantage II, which is essentially Advantage Multi without the heartworm and intestinal parasite component.
  3. Bravecto for Cats*
    This is one of the newer products on the market, and it is quickly becoming one of my favorites. Like the others, It is a topical that is applied to the back- but it only has to be applied every three months. The only downside is that you must apply a larger volume of product compared to Advantage or revolution, and the solution is somewhat greasy until it dries. It protects against fleas and ticks, but does not protect against heartworms or intestinal parasites. I recommend using a monthly oral heartworm prevention, such as Heartgard, if you’re using this product.
  4. Comfortis*
    Comfortis is a prescription product that is also available for dogs. We didn’t talk about it for dogs as I prefer Trifexis for dogs, which is essentially comfortis plus heartworm prevention. There isn’t a trifexis for cats, unfortunately, so you should pair comfortis with a monthly heartworm prevention. It is a tablet you must give once monthly, by mouth. The biggest downside is that this tablet is somewhat large, and can be difficult to give to cats as they can be significantly harder to give medicines to than dogs.
  5. Seresto
    Seresto for cats is an over-the-counter collar that prevents fleas and ticks for 8 months. I really like this product. It is very safe, effective, and has a safety release mechanism in case you cat gets caught on something. I don’t recommend any other type of flea collar for cats- seresto is different from other collars because it is safe and effective, isn’t greasy or smelly, and doesn’t contain chemicals that are highly toxic to cats.

Question for readers: Are you guilty on skimping on your cat’s monthly flea and heartworm prevention? Have you ever had a good or bad experience with a product? Share below!

My 5 Favorite Flea Preventions (For Dogs)

Hi guys! Now that you know how important flea prevention is for your dog, you are probably feeling a little bit overwhelmed trying to figure out which product is the best. In this post, I am going to tell you which products are worth every penny- which to me means that they are highly efficacious, safe, and science based. I hope you enjoy the list. Check back on Sunday, where we will be talking about my five favorite flea preventions for cats, and next Thursday for my five LEAST favorite flea preventions.

Disclaimer: I have not been sponsored or paid to write about these products by anyone. These opinions are my own and are based of 2 years of experience as a veterinarian and a combined total of nearly 10 years of working in the veterinary medical field. My opinions do not necessarily represent the views of my employer or of the veterinary medical profession as a whole. To ensure complete transparency, products listed below that are followed by a star are sold in the veterinary practice where I work. Products that are underlined have been given to me as free samples by company representatives.

I only recommend products that are scientifically based, effective, safe, and that I would feel comfortable using on my own pets.

My Top 5 Favorite Flea Preventions for Dogs:

  1. Trifexis*
    Trifexis is my absolute favorite antiparasitic product on the market. It is a one monthly prevention that is given orally with a meal. It protects against fleas, whipworms, hookworms, roundworms, and heartworms. It must be purchased with a valid prescription from a veterinarian and an up to date heartworm test. Animals that have had seizures before should not take this (or any oral flea preventatives). This product should always be given on a full stomach, as rare GI upset can occur. My dog, Gemma, is on this every month and has been since she was 5 months old. She looks forward to taking her special “treat” and has never had a problem with it.
  2. Revolution*
    This product is a heartworm and flea preventative (it also protects against one species of ticks, and is effective against mange mites). It is applied topically. Animals should have a heartworm test before purchasing this, and this should be purchased from a vet. Revolution is one of the safest products on the market. I’ve used it “off label” in very small pets such as neonatal puppies and kittens, guinea pigs, ferrets, and rabbits. The newest addition to my family, Franklin, is on this preventative as he is currently too small for anything else.
  3. Nexgard*, Bravecto* Chewables
    These are some of the newer preventatives out there. Simparico is another comparable product, but it is not on this list as I am not familiar with it. These products are given orally, and are flavored chewable tablets that most dogs actually love to take. Like other oral products, don’t use them if your pet has seizures. These products also kill ticks, but do not protect against heartworms or intestinal parasites. Nexgard lasts for one month and Bravecto lasts for 3 months. You do not need a heartworm test to purchase these, although they should be purchased from your vet. My oldest dog, Willow, takes Nexgard (and heartgard) every month. She is very picky about pills, but she loves them!
  4. K9 Advantix II
    K9 Advantix and Seresto (below) are made by Bayer Health and are the only OTC products that I trust. K9 Advantix is highly effective at killing and repelling fleas, ticks, and mosquitos. It is applied topically. You can get this product at many pet stores, and you don’t need a prescription from your veterinarian. Be very careful with this product if you have cats- if a cat is exposed to the product while it is still wet or if it is accidentally put on a cat, it could be fatal.
  5. Seresto Collars
    Seresto collars are the only collar you’ll ever hear me (and probably most other veterinarians) recommend. How are they different from other collars on the market? For one, they aren’t greasy, smelly, or gross. It lasts for a whole eight months and has been extensively researched and found to be very safe. The product has been rigorously tested- and is safe even if the collar is chewed on or ingested. Most other collars aren’t efficacious, are smelly and greasy, last for a month or less, and can be toxic if swallowed. My dog, Gemma, wears a Seresto collar in the summers (and also takes Trifexis) to protect her from ticks.

Question For Readers: Are you familiar with any of these products? Which are your favorite? Why?

My Flea Confession (and what you can learn from it)

Guys, I have a confession to make.

A few months ago, I was sitting on the couch with my fiancé watching TV. One of my cats, Thursday, hopped up in my lap. We have tortoise shell cats that are extremely sassy (we call it their “tortitude,”), and so it is a special occasion if they want attention. I seized the day and began petting her, only to become horrified a few seconds later.


“How could this happen?” I found myself thinking, “My cats only stay indoors, I have hard wood floors, and both of my dogs are on flea prevention!”

I immediately started laughing. I had just used the same excuses that my clients rattle off day in and day out, and I definitely knew better. I had been telling my clients for two years that they needed to have all of their animals on flea prevention- even the ones that are “indoor only.” And now, I realized that I wasn’t practicing what I preach!

It was humbling, to say the least.

Luckily, I immediately applied Bravecto for cats (a topical feline flea prevention that lasts for an entire THREE months), and the problem went away. I am extra careful now to make sure that I give the torties their flea and heartworm prevention every month, at the same time I give my dogs theirs. I hope to never be in a state of ‘flea-nial” ever again!

FLEA-NIAL: The state of denial a pet owner is in when they say “my pet doesn’t have fleas” (and their pet definitely has fleas).

Now, you can learn from my mistake. Here are a few reasons why ALL mammals in the household need to be on flea prevention:

  1. You can track fleas, flea eggs, or other parasites into your home. Fleas can come into your house on you or your shoes. Don’t worry- they won’t parasitize humans, our body temperature is just a little too cold for them.
  2. Your dogs- even if they are on flea prevention- can track parasites into your home. Many preventions need the flea to bite the pet in order to kill the flea. This means that a flea could “hitch a ride” on an indoor/outdoor pet, come in, jump off, and colonize your indoor-only pets.
  3. It only takes two fleas to start a family. Listen, kids. When a mommy flea and a daddy flea love each other very much… But, seriously. A female flea can lay over 500 eggs in her lifetime. And those fleas can lay 500 eggs. Two fleas can easily start an infestation.
  4. Dormant stages of the flea’s life cycle can live in the environment for MONTHS. I usually tell my clients that it takes at least 4 months to get rid of an active flea infestation in your home. That is because certain life stages of the flea, especially the pupal stage, can live in your environment for up to 4 months. Because of this, you must use your products continuously and year round to prevent reinfection of your pet.
  5. Fleas can survive the winter. Especially if they are indoors, on an inside only pet, or laying dormant in your home. I see almost as many animals suffering from flea infestation in the winter as I do in the summer. I suspect that this is because owners are not as diligent as applying flea prevention in the winter time.

Now, hopefully you have learned from my stupidity and now know the reasons WHY you need flea prevention, even in indoor pets. If you liked this post, please comment, share, or join the conversation on twitter @KatieHoganDVM

Veterinary Myth Busters: Part One (an overview)

Greetings, earthlings! Welcome to the first post in a mini series I am doing called:

Veterinary Myth Busters

I tweeted over the weekend, asking my veterinarian friends what common veterinary medicine myths (#VetMedMyths) annoy them the most. Today, we’ll go over the top 3 from the list and briefly go over why they are not true. Later on, we will unpack each topic in a little more detail to break the cycle of misinformation that permeates the internet. Stay tuned so that you can be the most informed pet owner at the dog park!


“Grain free food is better for dogs, because most are allergic to corn.”

Submitted by: Me, @KatieHoganDVM

I hear this one daily in practice, and it drives me nuts. Most dogs with food allergy are not allergic to the grain in the diet, but to the protein (the beef, chicken, turkey, etc) in the diet. Grain free diets often come coupled with novel protein sources (proteins that your dog’s immune system hasn’t seen before), and so when they make the switch to grain free they see an improvement because they changed the protein, not the grain.

The “corn is bad for dogs” myth has been perpetuated by the excellent marketing strategies of certain pet food companies. These guys claim to sell “premium” products fit for the wolf living in your living room. Sorry, people, but your pug mix is not a wolf! Even if he was, corn would still not be bad for him. Corn is quite nutritious for dogs and other species. I encourage you to talk to your veterinarian, do your research and feed a high-quality food with meat as the first ingredient on the list. Some dogs do well on grain free food- but for most dogs (80-90%), you’re wasting your money.


“I don’t need heartworm and flea prevention because…”

Submitted by: @BalyBoo

You would not believe some of the ways people finish this sentence! The people who say this think that their pet is immune to the need for parasite prevention because they live in a gated community, their dog never interacts with other pets, they spray for mosquitos, they have hardwood floors, they’ve never had a problem before…. The list goes on and on! Later in this series, we’ll break down the many excuses and bust each one of them individually. But, for now, we’ll keep it short and sweet: Heartworms are spread by mosquitos, who can quite literally survive anywhere. Unless you keep your dog or cat in a plastic bubble…. he needs heartworm prevention!

As for fleas, they are extremely resilient, and can be spread by wildlife and feral/outdoor cats. In my practice, I see as many animals suffering because of fleas in the winter as I do in the summer. If your pet has fleas, you need at least four months of flea prevention to get rid of the current infestation. And if your pet goes outside or you have other pets that go outside? All pets in the household need flea prevention. Remember the old saying- an ounce of prevention is worth a pound of cure!


“Spaying my dog will make her sick”

Submitted by: @TiffanyHeaton

I hear this one a lot. In fact, it is 100% the other way around! Spaying your female dog before her first heat cycle reduces her risk of mammary cancer to a 0.5% chance compared to the 25% chance (1 in 4 dogs) for females who are not spayed or spayed after their second heat cycle. Breast cancer accounts for over half of all cancers in female dogs, and by spaying early you nearly eliminate this possibility!

Another common condition in older, unspayed female pets is pyometra- a serious infection that can be life-threatening and requires immediate (and very expensive) emergency surgery. We see this condition (as well as mammary cancer) in feline patients as well. Simply put, you will greatly increase your pet’s life expectancy and quality of life if you spay her before she is 6 months old!

Thanks for joining us for part one of the #VeterinaryMythBusters series. Check back on Sunday, where we will be investigating the grain free food myth!
