Pet's info: Dog | Pit Bull Terrier | Male | 1 year and 1 month old | 14 lbs
My husband brought home a 14 week old pitbull puppy 2 weeks ago. We were just told he hasn't had his parvo shots so we got his first one yesterday. He looked skinny a few days ago so I gave him round worm medicine 3 days ago. Last night he started throwing up and he has do this all day. My husband found the worms in his stool today dead. But this puppy looks skinny and gas vomited non stop all day including 10minutes ago. His vomits is clear with lil white foam. He drinks a bit of water.

I would be worried about parvo with those symptoms or a bacterial infection. If it is parvo, he was exposed and incubating the virus before the vaccine so it was not protective. The best thing to do is feed boiled chicken and rice and try to keep him hydrated with pedialyte or Gatorade. I would try to find an ER clinic or a vet that takes after hours calls to get him seen today for a test and further treatment

In a young puppy with vomiting and lethargy our main concerns include GI parasites, parvo virus, GI foreign body (i.e. dog ate a piece of a toy, fabric, rock, etc.), or dietary indiscretion (i.e. eating something they aren't used to, like a new treat or food from the trash). It would be safest to have your puppy see the veterinarian for an exam and to test for intesitnal parasites and parvo virus. If these are negative, the vet may recommend an x-ray or may treat your dog symptomatically (with anti-vomiting injections) depending on the exam and history.

Yes, it is entirely possible he could have contacted parvovirus if he isn't fully vaccinated, and has been around other dogs of unknown vaccine status. I recommend taking him into the vet now. Parvovirus is life threatening, and it has no cure. The best chance of survival is intensive supportive care in the vet's clinic. The vet can do a snap test to determine if he does have parvo, and can treat from there. It's best to rule it out in case he does have it, so he can get treatment right away.

Poor Barfi. To have the best chance of survival, your dog does need to be hospitalized. Parvovirus treatment consists of aggressive supportive care to control the symptoms and boost your dog’s immune system to help him win the battle against this dangerous disease. Dogs infected with parvovirus need intensive treatment in a veterinary hospital, where they receive antibiotics, drugs to control the vomiting, intravenous fluids, and other supportive therapies. I would take him into the closest vet now.
