Deworming Puppies

Deworm your puppies early on.


Q. At what age should I deworm my puppies?

Dr. Jon GellerA. All puppies should be dewormed starting at 2 weeks of age, and every two weeks until they are about 3 months old. At that time, they should be put on some kind of preventative that will control heartworm, fleas, ticks and worms.

Almost all puppies develop some kind of intestinal parasites, such as roundworms and hookworms, due to their close confinement and lack of hygiene. The worms are present in their stool, and they re-infect each other when they ingest stool while licking their feet or fur.

The most effective dewormers are prescription strength and are only available from your veterinarian. Your veterinarian should consider dispensing enough doses so you can deworm your puppies at home and only come in for scheduled exams and vaccinations. Your veterinarian may also want a stool sample to make sure the medication is working as intended.

We rescued a puppy that seems less than a month old. She has been passing stool with worms. Can we give them deworming meds? What's the name and what's the doses and frequency?

We just brought home 2-two month old collie puppies this past Saturday. They went to the vet and the stool specimen results show round and hook worms. Now I have had collies all of my life but have not had to deworm a one until these two. Now my question is this-the puppies go in the grass and the stool sticks to the blades of grass. I'm planning on giving them the medication in the next few days and wondering-where should they excrete their business if it needs to be picked up and the poop will be loose? Also how long does the loose stools last after deworming?
