My almost 4-year old went to the groomer on Friday, and it took an extra long time because of shedding. But I noticed yesterday in the sunlight that on his sides - just behind the shoulders and on his flanks - his undercoat is basically GONE. I've never seen him lose so much undercoat before. He's still got plenty everywhere else, and since the bare patches are symmetrical I assume it's okay, and I'm seeing in some other posts that sometimes they can definitely lose a lot. But I just wanted to check because this amount of loss, for him, is definitely new, and maybe he was groomed too vigorously? I dunno!

When Anya is in the middle of a coat blow--some of it will come out in chunks, other areas will come more gradually, so she'll have spots that look incredibly bald and sparse by comparison. It does even out with continual brushing and your pup will be back to his handsome self

I thought this when Klaus blew his coat last year. Usually his hind legs are so dense with fur you can hardly get to the skin. When he blew his coat you could get to his skin just by running you hand over it real quick. I thought he we going to go bald!

Oh good thank you both so much for the replies! I won't worry then, I'll just keep brushing...and brushing We have had an early, hot spring, so maybe that's it!
