What's the best and safest OTC dewormer for my 5-week-old puppy?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed | 1 month and 7 days old | 33 lbs

I have a five week old puppy she'll be six weeks on the fifteenth of this month. She's between five to ten pounds. The night we got her she threw up several times some of it having roundworms in it. They rarely show in her poop and she's stopping throwing up. Her appetite is normal and she drinks plenty of water. I can't take her to the vet is there a medicine I can buy for her? I read about Nemex-2, Safe-guard 8 in 1 and Panacur C. Are any of these safe for her? Which would be best if they are?

There are non-prescription, over the counter, deworming medication is available. They are all usually safe for puppies as long as given according to label instructions. After giving a dewormer dogs can have diarrhea and you could see worms pass in their feces. Most dewormers would take care of the common GI parasites such as roundworms and hookworms. The dewormers you listed are all safe for puppies her age. You could use any of those dewormers however if the vomiting worms continue or she has diarrhea that does not go away within a day she should likely see her veterinarian as it could require a prescription strength dewormer.
