My puppy vomited worms and has bloody poop. Can I give dewormer?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 1 month and 1 day old

My one month puppies (3 out of 5) vomitted white-like worms and they have red to blackish kind of poop. I don't know what to do, I am planning to go buy a dewormer in the market since there are no available vet coz it's a sunday. Is it okay if I let them take a dewormer? Im worried bcoz they might be losing weight.

If they looked like spaghetti, they were probably roundworms. All pups get them from their mother, so it's expected that they would have them. They should be dewormed every 2 weeks starting at 2 weeks of age until 8 weeks, and then should have a fecal test run. You may see more worms coming out as they die. For the weight, I'd recommend checking weights daily with a baby or kitchen scale so you can bring them to the vet if they aren't gaining. I hope that helps!
