My Basset Hound, Copper, is male, 1 and 1/2 yrs old, and about 60 lbs. Lately he has lost his appatite, and has had diarehha. We took him to the vet and they gave him antibiotics (about a week ago). For the last 2 wks or so he has been having (for lack of a better word) tremors. Like he's shivering. Took him to the vet yesterday, he's lost almost 2 lbs from dehydration. They gave him fluid and instructed us to watch him to make sure he dosen't have a seizure. He is also whining alot. (Sometimes he does that when he wants to go for a walk, but lately it's been for no apparent or visable reason) The vet seems to have NO CLUE what's wrong with him, can you help me figure out WHAT IS WRONG WITH MY DOG????
