Adult animals should be given an antiparasitic before the annual vaccination if the owner does not use preventive deworming - that is, if he does not use internal worming medication 2 times a year, at least.
If preventive deworming is carried out systematically - then, before the annual vaccination it is not necessary to give a medication for internal parasites.
Be sure to use the treatment before the first vaccination for puppies and kittens - as they are most likely to have worms.
Preventive deworming is a one-time use of an antiparasitic agent.
In the presence of worms - a treatment regimen is necessary, which depends on the type of worms, age of the animal and risk group in which the animal lives (e.g. kennel, shelter, multi-cat house, overnight stay, street housing, etc.). In this case, you need to consult a veterinarian.
Cats that live exclusively at home, preventive treatment against internal parasites is also necessary.
Cats that live only in doors, preventive treatment against internal parasites is also necessary.
Kittens and puppies should be treated at least once a quarter during their first year of life.
Answer: puppies and kittens BEFORE the first vaccination is mandatory, treatment of adult dogs and cats is carried out regardless of vaccination.
