I got my rescue greyhound just over a month ago. I've noticed that her hair all over is looking a little thinner and she actually has a couple of bald spots now - on the back of both haunches, one on her tummy and on her "elbows" on her front legs.
She's not scratching a lot, but I have noticed her "chewing" herself a few times - but nothing excessive. I frontlined her a week ago and they said she'd been done at the rescue as well.
I certainly can't see any fleas (but she's black) as this was the first thing I thught of. Could it be a coat change type thing as she was living outside before and is now inside? Could it be a stress type reaction to a new home? Is it likely to be fleas?
