How To Find, Treat, and Prevent Fleas on Puppies

Is your puppy itching constantly, biting their skin, or losing fur? If so, they may have fleas. These tiny parasites live on a dog’s skin and within their fur, creating significant discomfort. 

Fleas on puppies are common and spread easily between pets. Other parasites, like ticks, can also cause irritation and carry diseases. This is why flea and tick protection for puppies is so important.

Knowing the signs of fleas and how to treat them effectively can help keep infestations from getting worse. Fast-acting prescription medications that offer broad-spectrum coverage are the best way to treat fleas and other parasites—and help keep them from coming back.

How To Find Fleas on Puppies

If your puppy has fleas, you may notice the following signs:

• Small brown bugs (fleas) in the fur
• Tiny black specks (flea dirt) in the fur or on bedding
• Frequent itching
• Biting or chewing skin
• Hair loss, especially near the tail base
• Red, inflamed skin or scabs
• Restlessness

How To Get Rid of Fleas on Puppies

To get rid of fleas on puppies, your vet may recommend a combination of flea remedies for puppies, including flea treatment, regular grooming, and bathing. This approach helps eliminate fleas and reduce ongoing irritation.

Remove Fleas With Flea Comb

You can use a flea comb to brush your puppy’s fur to trap adult fleas, their eggs, or flea dirt.  After brushing, dip the comb in hot, soapy water to clean it and trap the fleas. This should be paired with environmental cleaning, as fleas can hop back onto your puppy if they are still living in carpet or pet bedding.

Bathe Your Puppy

You can bathe your puppy weekly in an age-appropriate shampoo specifically formulated to kill fleas on contact. While dish soap is often used by pet parents for this purpose, it can dry out your puppy’s skin and lead to irritation, so it is best to choose a pet-safe shampoo instead.

Use a Vet-Recommended Flea Treatment

The most effective way to help get rid of fleas is to use a flea treatment prescribed by a veterinarian. Flea treatments for puppies come in a variety of forms, including oral pills and chewables, topical solutions, and collars.

For example, Credelio Quattro/Credelio Quattro-CA1 (lotilaner, moxidectin, praziquantel, and pyrantel) is a flavored chewable tablet for dogs and puppies who are 8 weeks of age or older and who weigh at least 3.3 pounds. Available by prescription only, the tasty tablet kills more than 99% of fleas within eight hours of administration and remains effective for an entire month.¹

Talk with your vet before starting any new flea treatment. They can help you choose the best parasite medication for your puppy. Because puppies grow so quickly, you’ll need to size up the flea treatment as their weight increases to ensure they stay protected.

How To Get Rid of Fleas in Your Home

An important element of getting rid of fleas on your puppy is eliminating them from their environment.

Even if you treat your puppy, fleas in the home can still jump on them and reinfect them, leading to unresolved symptoms and discomfort. This is because oral flea products kill fleas after they’ve bitten your puppy, but they do not repel them. As a result, fleas may still jump on your puppy and bite them before the medication can kill them. Fleas also lay eggs in carpets, bedding, and furniture. These eggs can hatch and cause ongoing infestations if the environment is not properly treated.

Follow these vet-recommended tips to clean your home:

• Vacuum carpets and furniture daily to remove all life stages of the flea. Empty the vacuum canister into an outdoor garbage can immediately.
• Wash pet bedding or blankets in hot, soapy water weekly.
• Consider using a pet-safe peppermint spray on bedding or blankets in between washing.
• Use a pet-safe yard treatment, such as Advantage Yard & Premise Spray, to get rid of fleas and ticks outside of your home.

How To Prevent Fleas on Puppies

Starting your puppy on broad-spectrum parasite coverage early and ensuring a clean environment are critical to keeping infestations at bay. Avoiding high-risk animals also reduces their risk.

Start Flea Protection Early

Puppies typically begin flea protection at 8 weeks of age, and they should be kept on year-round coverage.

To protect against other parasites, your veterinarian may recommend a broad-spectrum coverage option, like Credelio Quattro/Credelio Quattro-CA1, which offers the broadest parasite coverage of its kind,* targeting seven types of parasites^§ in one easy-to-give chewable tablet.

Credelio Quattro/Credelio Quattro-CA1 is the first and only chewable of its kind* for dogs that covers ticks, fleas, heartworm disease, New World screwworm larvae, and three intestinal worms that can be passed to humans—roundworms, hookworms, and three species of tapeworms.**

Again, speak with your veterinarian about the best puppy flea protection for your pet’s individual needs.

Keep Puppies In a Clean Environment

Keeping your puppy’s environment clean is important for their comfort and to protect them from unwanted parasites. Wash your pet’s bedding every one to two weeks to prevent fleas from thriving, and vacuum regularly for good hygiene.

Because fleas also seek shaded, moist areas to live in, ensure your outdoor areas are well-maintained to deter fleas.

Avoid High-Risk Areas and Animals

Dogs can be exposed to parasites, such as fleas and ticks, any time they go outside. However, visiting high-risk areas can increase their likelihood of exposure.

While dog parks are a great way for dogs and puppies to run off steam and socialize, they also carry risks of parasite exposure. Not only can fleas be spread at these parks, but dogs may be exposed to intestinal parasites, such as roundworms, hookworms, and tapeworms. In fact, one study found that just over 20% of dogs visiting dog parks were actively shedding an intestinal parasite that could be spread to other dogs. If the park is not maintained well, tall grass can lead to high tick populations as well.

For these reasons, it is important to provide your puppy with year-round, comprehensive coverage against parasites to help keep them healthy and avoid high-risk areas when possible.
