Dear Dr. Kay: My 2-year-old miniature pinscher has a balding patch on the front of his neck to the tops of his legs. His skin is not discolored, and there are other small spots on his belly and legs where it looks like this is also going to start. He is on medication, and my vet plans to follow up in 4 to 6 weeks, but I am concerned that by then my dog will be hairless. He is primarily indoors but has access to the backyard where we have planters. Do you have any suggestion, thoughts, advice? —Teresa
DEAR TERESA: Many skin diseases produce a similar outward appearance, so some diagnostic testing is usually necessary. Give your vet a call and find out what the thinking is about your dog’s bald patch. If the abnormal site seems to be getting worse rather than better, don’t hesitate to schedule your pup’s recheck appointment sooner rather than later.
