Well, we just adopted a dalmation mix from the pound a few weeks ago, and her nipples are very big and...er...dangly. We know she's spayed as all dogs from the pound come spayed and we clearly see her incision. Could this mean she's had puppies before, even though she's only a year old? And how long will it take before they get back to normal? It's not a very attractive look, I must say!
