What deworming products are safe for a mare that is lactating?

Pyrantel (roundworms, hookworms and whipworms) and Drontal plus (also effective against tapeworms) are safe for nursing female dogs. Intestinal parasites are zoonotic/transmissible to humans by fecal/oral contact so be super diligent about hand washing after handling her or her pups. It is likely that all her pups have worms now too but they should be at least 6 weeks of age before deworming with its pyrantel. Good luck and congrats on the puppies!

Many deworming products are not recommended once pregnancy is established. Tapeworm medications, in particular, can be quite toxic. If you are concerned that your cat has parasites, I recommend that you take a fecal sample to your veterinarian for examination. Your vet can identify the eggs of any parasites your cat may have using a test called a fecal float exam. S/he can then prescribe the safest, most effective dewormer to use in a pregnant cat for that particular parasite.

Some wormers can be excreted with the milk. This is not necessarily damaging to the pups, however you should read the wormer's instruction sheet before giving it to your lactating dog. It will state whether it is suitable for lactating bitches. Puppies can be wormed with puppy wormer at 2 weeks.

Feli D tablets seem to contain praziquantel and pyrantel pamoate, both of which should be safe to use in a nursing queen. The kittens are actually old enough to be dewormed as well if necessary, but you may need to use a different product since they are small.

If the stools are otherwise normal and there is no blood in the stool, then I would recommend the basic dewormer Pyrantel Palmoate, which treats for hookworms and roundworms. If your pets have obviously loose stool, then they may need a broader spectrum dewormer such as Fenbendazole. However it is always advised to get a fecal exam done first through your vet to identify which worms are present. Once that is done, the appropriate dewormer can be selected because not one dewormer will cover all possible intestinal worms).

Yes, it is safe to deworm a dog during pregnancy. Fenbendazole is a good wormer that is absolutely safe to use to reduce the worm burden. There are other wormers you can use as well. Make sure you read the instructions, they should also tell you whether a particular wormer is safe to use in a pregnant dog.

You should always follow the directions on the packet. It is advisable to worm pups at 14 days of age and the mother 24-48hours after. The combination you note is often not licensed for lactating mothers
