Shaving/trimming the coat of a GSD
I've had my gsd, Heidi, for two years now. She's a beautiful sable, but her coat has become rather long. When I spayed her a long time ago, my vet actually shaved her belly and part of her back. So now, the hair on her head/neck/shoulders is much longer (some maybe 4-5" long) than the back. I wanted to get her coat trimmed at my groomer, but I was told the only thing they could do is shave her down to 1/8"-1/4" (couldn't tell for sure, but said they'd leave it as long as possible).
Anyway, has anyone ever done this? Heidi is mostly an outside dog (we have an invisible fence on our 3 acres) and I want to make sure her coat is short so she can still stay somewhat comfortable during the summer.
