Our 1.5 year old basset's fur is thinning on her neck, and she has a bald spot on the front of her neck that looks a bit raw. She also had diarrhea today while we were at work and her ear hair is thinning. She also scratches alot. We are going to take her in to the vet tomorrow but do any of you have any ideas what it migh be? She did have some thinning hair when we got her but were reassured it was because she had puppes not to long ago.
