Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 1 month and 21 days old | 4 lbs

I just got a 6 week old puppy. We've had her for 1 week today. Noticed worms in her poop and blood. So we dewormed her saturday. She's pooping dead worms today and it's nothing but blood and worms. But she wont eat or drink water. When squirt water down her throat she vomits it back up immediately. Please advise.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Sakari! If Sakari is not eating and vomiting when drinking she needs to see a Veterinarian. She is so small at just 4 lbs that she is at risk for dehydration and low blood sugar. When dogs defecate blood that indicates colon inflammation and also indicates that severe dehydration is even a higher risk. Sakari may have such a high worm burden that all the worms dying are causing stomach and intestinal inflammation or they are causing an obstruction. She also could have something else going on, especially if she isn't vaccinated, like parvo virus or another viral or bacterial infection. The best thing for Sakari is to see a Vet today for supportive care. I wish you the best!
