Hello all we have a 15 week old pup name Chuck. We've had him for a week and the day we got him he had a little cough he got worse after a couple days! We took him to 3 different vets and had 2 xrays done and blood work. The xraysvare good we are waiting for blood work. He has greet snot coming from his nose and is having trouble breathing. He has been on a antibiotic for 4 days I think its clavamox. He is very lethargic and and is vomiting when he eats and drinks. He looked like he had a seizure last night. He stood up real fast and fell on his back and peed on himself. We took him to the vet again and 2 of them said it looks like distemper but he has had 2 vaccines for it already. So I dont want to believe its that. Has anyone else experienced this please help!
