Almost every puppy and kitten is born with worms or picks them up in the first weeks. Regular deworming keeps them growing well, helps vaccines work, and protects the children in your home.
Roundworms can pass from mother to puppy before birth and to kittens through milk. Hookworms, tapeworms and whipworms are picked up from soil, grass, fleas and other animals' faeces. Heavy worm loads cause a pot belly, diarrhoea, poor growth, anaemia and a dull coat, and a puppy full of worms may not respond well to its vaccines.
Some dog and cat worms can also infect people, especially young children who play on the floor or in the garden. Regular deworming is part of keeping your whole family healthy.
Young animals need deworming often because they keep picking worms up while their immunity develops. A common schedule is:
Most vets recommend deworming adult pets every three months. Your vet may advise more often if your dog eats things outdoors, hunts, lives with small children, or lives in an area with a lot of stray animals, and less often for a cat that never goes outside.
Pregnant and nursing mothers need a deworming plan from the vet, because some medicines are not safe during pregnancy.
Many pets with worms show no signs at all, which is why deworming is done on a schedule and not only when you see worms.
Pets get the common tapeworm by swallowing fleas while grooming. If your pet keeps getting tapeworm, treat for fleas at the same time, or the worms will keep coming back.
Write the date and the medicine on your pet's card each time, and set a reminder for the next one. Ask your clinic to add deworming to your pet's record so their reminders cover it along with vaccinations.
Puppies every two weeks from 2 to 8 weeks of age, then monthly until 6 months. Most adult dogs are dewormed every three months, but follow your vet's advice.
Kittens every two weeks from 3 weeks of age, then monthly until 6 months. Adult cats are usually dewormed every three months, or as your vet advises for indoor cats.
Many vets deworm a few days before a vaccine or on the same visit. Ask your vet; the aim is a healthy, worm-free puppy when the vaccine is given.
