I work at a boarding kennel that does professional grooming. Most of the Pyr's DO come in for a "summer cut!" They just can't take the heat; and this is on Cape Cod!! Actually, they look pretty spiffy with their summer "doo!" And they seem to act as though they really feel better! My DLH kitty also gets a lion cut in summer, and he feels like a new man after it! Don't fret! She'll feel better, be more comfortable and it grows back quickly. It costs about 35.00 here. And they spend quite a bit of time washing, clipping and pampering. I say go for it! My husky/shep can't take the heat either. She spends all summer under a tree or digging a cool, deep hole to lie in! Montana is just beautiful!!
