Older Jack Russell getting brown spots of hair

Merv, my Jack Russell (about 11-13 years of age) has started getting brown spots of hair (almost like freckles, but they are in the hair, not the skin) all over. They are faint, roundish, and light brown. The vet has no idea what it is.

Two things happened before they started: had an operation on his parathyroid gland and the only other change is that he started eating rabbit, which he had not had before this. I stopped the rabbit, but the spots are still there.


Next question - he really pants and slows down in the heat - we walk a mile and a half to and from work each day. He has water along the way, but is it too much for him otherwise and should we cut back.

He's a Hurricane Katrina Rescue so that is why there is a question about his age, but am guessing 11 - 13.

We live in New York City.

Thank you!
