Why is my dog's hair suddenly getting matted after 13 years? I've already figured out what I need to unmat her (a
We don't know what breed my dog
is. Most people guess at least part border collie, if not all border collie; others definitely see black lab and/or German shepherd in her. Her hair has always been smooth and shiny, with the occasional little whorl on her chest in the white part.
Over the last month or so, her hair has gotten a bit clumped in places. Also, the texture has changed. It feels more porous and not quite as smooth. The shedding blade
is doing nothing, which is a new development. Last time, a bath washed most of it out. This time, not even that helps. I can pick them out carefully with my fingers; what comes out is the usual reddish-black late spring undercoat that has always come out on its own with regular brushing and petting on our parts. It started over her left shoulder, which incidentally has a few cysts or lumps there that the vet said were benign. (That's probably a coincidence.) Now I've also found clumping under her collar (which I have checked and is not too tight) and where her back legs meet her body.
The dog has been under a good deal of stress lately. Her mommy was in the hospital for a week, and even when home has not paid as much attention to her. However, the other two members of the household have given her at least as much attention as usual, and there are additional people coming in and out, giving her attention, which she likes.
Could this be caused by stress, or hormonal changes due to age? The reason why I am wondering is if this is some sort of isolated incident, we'd just borrow a slicker brush instead of buying one. And based on what you guys say, we'd be open to taking her to a groomer or vet too.
