The 8 Best Flea Shampoos for Dogs

1. Natural Chemistry Natural Flea & Tick Shampoo for Dogs – Best Overall

Natural Chemistry Natural Flea & Tick Shampoo is our pick as the best overall flea shampoo for dogs. It features real oatmeal, which helps soothe the skin, and it kills fleas, ticks, black flies, and even mosquitos for up to seven days after use, without using harsh chemicals, so it’s safe to use on any dogs, even puppies. Since it relies on natural ingredients instead of chemicals, it won’t interact with other flea medication your pet might be taking, and we found that it has a pleasant smell that won’t overpower your room.

The downside to Natural Chemistry is that it doesn’t produce any lather, so it can be challenging to make sure you get everywhere, and you tend to use a little more product, which already runs out pretty quickly.

2. Hartz UltraGuard Rid Flea & Tick Oatmeal Dog Shampoo – Best Value

It kills fleas and ticks on contact, and the ergonomic bottle is easy to use and doesn’t spill, so there is no waste. We like that it comes with a flea comb which helps with the bath, and it will also help you detect them faster in the future.

The only downside we experienced while using the Hartz brands was that it has a bad odor, and some harsh chemicals make it unsafe to use on puppies and cats.

It won’t irritate your pet’s skin, and you can use it as frequently as once every three days until the fleas are gone. It’s easy to use and comes in a durable bottle that won’t leak or spill.

The downside to Miracle Care is that it doesn’t lather well, so it can be hard to tell where you have already cleaned. It also has a bad smell that some pet owners might not like, and though it does not bother our pet’s skin, some owners might prefer a brand without chemical ingredients.

Buyer’s Guide: Selecting The Best Dog Shampoo for Fleas

Flea Dog Shampoo Ingredients

Chemical Ingredients in Dog Shampoo

You will find several chemical ingredients like permethrin, methoprene, and others. These chemicals can be extremely effective against fleas, and if your pet only gets fleas occasionally, it can be a great solution. However, if your dog spends a lot of time outside and picks up fleas several times each year, the chemicals may start to affect your pet, and it may suffer from dry and itchy skin, among other things. Another problem with these shampoos is that manufacturers add other chemicals as well, like powerful fragrances, that can cause other problems for your pet.

If your dog is taking a medication like Frontline or one of the many others, a chemical-based shampoo might interfere and make them less effective, so we recommend choosing one of the other types.

Essential Oils in Dog Shampoo

Several essential oils, like lemongrass, can be a great substitute for chemical ingredients, and they can make a great choice if your dog occasionally catches fleas. Shampoos that use these oils often leave your pet smelling nice, sometimes for several days after the bath. However, many essential oils, including lemongrass, can be harmful to your dog if you use them too frequently.

Dog Shampoo Natural Ingredients

Natural shampoos usually use cottonseed or castor oil to help eliminate the fleas and ticks in your dog’s coat, and they also help make it soft and shiny. They are less dangerous to your pet’s health than the other options we looked at, so they are a great choice for someone with a dog that catches fleas every time it leaves the house. The downside to these shampoos is that they usually aren’t as effective as the others, so you will likely need to give your pet more than one bath to eliminate the fleas.

Dog Shampoo Bottle Size

Once you choose your cleaning ingredient, your next step will likely determine bottle size. We recommend getting more than you think you need, especially if you choose a natural brand or one that uses essential oils because you will usually need to use more and may need to give the pet more than one bath.

Dog Shampoo Fragrance

Almost all shampoos seem to include some fragrance to help the dog smell better when you are finished bathing. However, fragrance can be bad for your pet, especially from essential oils or chemicals. However, a bath here and there isn’t likely to do much damage, so it only becomes a big concern if your dog always seems to have fleas.

Other Things You Can Do For Dog Fleas

• If your home is infested with fleas, there is a good chance they will get back on your pet after the bath, so it’s important to remove them from home too.
• You can spread baking soda over the carpet and let it sit overnight before vacuuming for a great way to reduce the flea population in your home. Repeat as needed.
• We highly recommend using a monthly medication like Frontline to protect your pet from fleas. It creates a protective barrier over your pet, so the fleas and ticks never become a problem. It also protects them from heartworm, which they can get from mosquitos and other health problems.

Conclusion

When choosing your next flea shampoo for dogs, we highly recommend our pick as the best overall. Natural Chemistry Natural Flea & Tick Shampoo for Dogs is extremely effective and contains no harsh chemicals. It smells nice and is easy to use. Another smart choice is our pick for the best value. Hartz UltraGuard Rid Flea & Tick Oatmeal Dog Shampoo is inexpensive and comes with a flea brush that will help you remove the fleas as you bathe and check your results later.
