My dog hasn’t eaten or drank in 2 days, almost three and vomited yellow bile twice. He also has runny , like water, type stool and hes also extremely lethargic. Could this be the early signs of Parvo?

Hello, This unfortunately does sound very much like Parvovirus. As he hasn't eaten or drank in two days, he is probably extremely dehydrated and lacking nutrition. I would recommend taking him into a vet as soon as possible to get a parvo test done. Parvovirus affects the white blood cells in the bone marrow as well, so blood work can help know how affected he is by the virus. Most parvo treatments require at least a week of fluid therapy, nutritional therapy, IV antibiotics and anti-nausea medications. It unfortunately has about a 50% survival rate, even with treatment. Another thing that can cause vomiting, diarrhea, and lethargy, especially in younger dogs, would be foreign body obstructions (ie. eating a toy that got lodged in his intestines and needs surgical removal). This can be checked for with x-rays to see if there is any obstruction in the intestines. I hope this is helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
