Most puppies are born with worms, which is why puppies should be wormed at 2, 4, 6, 8 and 12 weeks of age, and then every three months for life with an all-wormer. Pregnant and nursing mothers should also be treated during mating, before the birth of their puppies, and every three months.
Worming treatments are easy and effective to use, but it is important to read the label, as you may need to use multiple products to protect your puppy against all types of worms. Heavy worm infestations in puppies should be repeated 10 days after the initial dose is administered. If you’re having problems administering your puppy’s treatment, ask your veterinarian for a demonstration during your next vet consult.
