Millie is the same! We've just got back from a week away, Mills stayed with my parents, (Mum is new to looking after dogs, so probably didn't brush her as thoroughly as she needs, but I'm glad she didn't have to go to kennels) and she's come home to us with a hooooge matt on her tum (which I finally managed to sort today, had to cut some out though, but been working on it since Sunday! and her armpits are bad too. Mind you, she spent the whole week wet through and up to her armpits in streams etc having a whale of a time! Trade off for having long hair I suppose!

I'd love to clip her cos she's a mud monster, but OH won't have any of it, yet it's me that has to do the grooming!
