I'm not sure if this is a health issue, but I'll start here. Chloe has bald spots behind both ears - right where you would scratch a dog behind its ears. At first I thought it was because Oscar was getting her -- he plays pretty rough. I've caught him playing tug-of-war with poor Chloe's ear!
She also has thinning hair on her hind quarters. Not real bad, but it is noticeable. She doesn't scratch, and there aren't any scabs or dry skin or anything. Just thin hair. I'm wondering if maybe it is just from poor nutrition while they wandered before the shelter picked them up.
I will be taking her back to the vet at the end of July for another heartworm test, so I'll be sure and have him check the spots. But thought I'd see if anyone has run into this with their dachsies.
