Most people know that the substances consumed by a mother are passed along to the baby. It is why human mothers are encouraged to quit smoking, limit caffeine and alcohol intake and even watch the spicy foods they eat.

You should be concerned about what kind of medications you are giving to a dog who is nursing a litter of puppies. After all, the chemicals you use on the mother can be passed to the pups through the mother’s milk.

Is There a Safe Flea Treatment for Lactating Dogs?

Luckily, the answer is yes. Several safe and effective flea treatments for lactating dogs are on the market today. Most flea medications for dogs are safe for pregnant and lactating dogs. Many veterinarians recommend the continued use of flea and tick medication as well as heartworm prevention medicines to stop the spread of parasites from the mother to the puppies.


Frontline is probably one of the most well known brands when it comes to Flea and tick pervention. The Frontline Brand Falls under the Boehringer Ingelheim corporate umbrella. Boehringer Ingelheim believes that the healthier our animals are, the healthier humans will be as a result.

Frontline Plus Spot-On

Frontline Plus is the flagship product of Frontline. It is a topical “Spot-On” treatment. This means you apply it directly to your pet. Usually between the shoulder blades.

Frontline Plus Kills all stages of the flea life cycle. It eliminates flea eggs, larvae, pupae, and adult. And it keeps on killing for up to 30 days after application. No wonder it is recommended by veterinarians.

Two chemicals make up the active ingredients in Frontline Plus. Fipronil takes care of adult fleas and ticks. The second ingredient, S-methoprene kills the eggs and larvae.  These chemicals are stored in the dog’s skin and released in their natural oils. Kind of a time-release poison for fleas and ticks.

The label on Frontline Plus shows it as a safe flea treatment for lactating and pregnant dogs.

Frontline Flea Spray is a good flea treatment for lactating dogs. The nice part about this product is that you can use it to kill adult fleas when you notice them on your dog.

The active ingredient in the Frontline spray is fipronil. Fipronil only kills adult fleas and ticks. It does not do anything for eggs and larvae. This means additional products may be needed to control the flea life cycle.

On the plus side of things, it works fast. Fleas will start dying off in about 2 hours as opposed the 12 hours it will take to see results with the Frontline Plus Spot-on product.

Again, Frontline labels this product as a safe flea treatment for lactating dogs.

Bayer Advantage II

If you want a brand with name recognition, you can hardly go wrong with Bayer. The German-based Bayer started operation in 1863.  the company’s primary focus is Human and veterinary pharmacutacals. With over 150 years experience, you can trust Bayer.

Bayer Advantage II is also a topical flea and tick treatment. The products claims to start killing fleas in 12 hours and continue killing for up to 30 days. the method of application is much the same as that of the frontline product. simply cut the tip off of the pipette of medication and apply between the dog’s shoulder blades.

The chemicals Advantage II uses to get the job done are a little different than those found in Frontline. Advantage II uses imidacloprid to attack the nervous system of the adult flea which causes paralysis and death. The second ingredient is pyriproxyfen, an insect growth inhibitor. This affects the egg and larval stages of the fleas. Bayer states these chemicals and the Advantage II product, in general, is a safe flea treatment for lactating dogs.


Capstar is an Oral pill. It starts working in as little as 30 minutes. Perfect for halting a full-blown flea infestation on your dog. however, the downside is there is no residual kill. So, unlike topical treatments that keep killing fleas for up to 30 days after treatment and flea collars that can work for months on end, Capstar works for that day. The makers say it is safe to give the medicine every 24 hours. The packaging also says it is a safe flea treatment for lactating dogs.

Capstar is relatively new on the market. I know the first time I heard about it was at my vet’s office a couple of years ago. I remember thinking how awesome it was that you could just give your dog a pill and be done with fleas. No messy applicators. No warning the kids not to pet the dog until the spot-on stuff dried. What I didn’t realize was that it only worked for a day. Still, a good option if your dog has a flea problem that needs to be halted immediately, like in a nursing situation. Don’t want to pass fleas on to the puppies.

Capstar’s active ingredient, nitenpyram, only works against adult fleas. It does nothing to control other stages of the flea life cycle. So, once you get the infestation under control, you will want to start a more long-term flea and tick prevention for your dog.

Seresto Collar

The Seresto flea and tick collar is my absolute favorite choice for flea treatment for lactating dogs, pregnant dogs, puppies, and dogs in general. This collar couldn’t be easier to use. Just put it on and it protects against fleas and ticks for up to 8 months. No messy application. No nasty smell. You don’t have to remember to put flea medicine on every month. One collar will last an entire flea season in most areas of the country. and the price is better than buying a huge box of topical treatments.

Seresto also has breakaway points just in case your pup gets hung up on something and needs to break free. It can be worn with other collars, and it does not require a prescription.

If you are looking for a worry-free flea treatment for lactating dogs. the Seresto Collar is the one to choose.

I Have Heard Peppermint Oil is good for fleas. Can I use it on my lactating dog?

The good thing about peppermint oil for fleas is the fact that it is an all-natural solution. The bad part is, it may not be great for your dog.

Rather than going to the essential oil aisle and picking up a bottle of peppermint oil, You may want to grab a product that is already mixed and labeled for flea protection.

Vet’s Best Home Spray uses peppermint oil and clove oil to ward off fleas and ticks. I would be more apt to use this product than attempt to make a mixture myself and hurt my pup. Remember, arsenic is all natural, too.

Are There Any Other Options?

When it comes to ridding your home of fleas or choosing the right flea treatment for lactating dogs, there are a couple of things that you can do to make sure the little pests stay gone.

  1. After bathing your dog, use a flea comb to remove any fleas that are still hiding out in their coat. Dip the comb in a glass of water mixed with a drop of mild detergent after each pass.
  2. Wash all of your dog’s bedding on the hottest setting and dry on the hottest setting. Fleas like warm and moist. High heat will wipe them out.
  3. Vacuum the house daily and thoroughly. Make sure to get any furniture where the dog lays.
  4. Check for fleas periodically. Put on a pair of tall white socks and walk through the house. Inspect the socks for “riders” when you are done. make sure you walk through some of the darker corners of the house, as well. Fleas hate sunlight.
  5. Find the source of the fleas. If they are coming in from the yard, Make sure you treat your yard for fleas with a spray. Inspect the yard for cool shady areas that might harbor fleas and open it up to more sunlight. anything you can do to destroy their habitat will make you and your dog much happier
