My puppy has worms in its poop. Should I deworm or see the vet?

Pet's info: Dog | Great Dane | Female | unspayed | 3 months and 1 day old | 25 lbs

Hi, i recently took in a Great Dane puppy from a foster home. She is 8 weeks old and i have already scheduled an appointment for her vaccinations. I have reason to believe she may have contracted round worm as i saw several worms in her stool similar to those i have found in the past when my other dog was a puppy. I treated my other dog with a deworming medicine and i thought about doing the same for this dog. Should i use the medicine or should I wait and ask the vet about deworming?

If your appointment is in the next week or so I would recommend just waiting until you can see your veterinarian. They can test a stool sample to confirm that roundworms are present, and can recommend the best deworming protocol for your area. Intestinal parasites are very common in dogs and often do not cause many symptoms. If she is having diarrhea you may want to try to see your veterinarian sooner. Roundworms are zoonotic, meaning they can be transmitted to people although they migrate through organs instead of infecting the intestinal tract. You should wear gloves when handling stool and remove all feces from the yard. You also may want to ask about risk of transmission to your other dog. https://www.cdc.gov/parasites/toxocariasis/gen_info/faqs.html
