My puppy has Parvo, is unresponsive, and breathing hard. What's wrong?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 2 months and 1 day old | 3.8 lbs

My puppy is having Parvo. A local vet looked into him and gave him antibiotics. He was fine earlier today until now. He's unresponsive and having a hard time breathing. Any advice? Or diagnosis?

I'm really worried about Nata - you need to see a veterinarian right away. If the vet you saw earlier isn't open I'd recommend going to an emergency hospital. Nata could have low blood sugar secondary to parvovirus, or he may have aspirated from vomiting causing pneumonia and trouble breathing. It also might be that the parvovirus is causing severe dehydration or a blood infection (sepsis).
