This is serious. May be distemper and should be seen by a vet asap. Your pup could die if not treated quickly.
My New Puppy Is Throwing Up, Has Diarrhea,is Very Lethargic, And Wont Barely Drink Or Eat. What Could Be Wrong With Him?
You need to get your dog to the vet ASAP!!!! Make sure you try to encourage drinking. He might have a little stomach upset or a bug. Call up your vet and ask them what to do. HURRY!!!!
I'm sorry. You need to take your pup to the vet now. It may be a severe parasite infestation or a bacterial infection or something but those are also signs of parvo. If your pup get's help soon enough your vet can prescribe Tamiflu which seems to help a lot but not later into the progression. Those are pretty much universal signs that they need help asap whatever the problem.
