Once again, I have to say that this is my FIRST puppy. But anyway, my Yorkie Maddy has been shedding a lot lately. Like, her coat seems to be come out in little pieces that are all over the house & in her brush. I know that dogs shed, but should so much be coming out? Some people say that it may be because we brush her so much, but if we don't brush her at least twice a day, she becomes very matted.

Also, the fur at the top of her head has begun to change colors from brown & black to gray? What is this about? We've been to the vet a lot (about other issues) so maybe it's not a big deal. I just want to be sure.

Maddy is currently taking heartworm medicine & she just had her rabies shot a little while ago, could these be the sources?
