Has your dog ever been treated for a bladder infection?
My poor little dog (shih tzu will be 8 years old April 22nd) and was up all night long last night vomitting for 3 hours, I called the vet and took him in to see Dr. and he has a bladder infection.
He got 2 shots and antibiotics meds. He is my baby and spoiled rotten.
