Boo I keep shaved in the summer, but with his head and legs left a little long.
Gracie's first cut was about 1 1/2" long and a little longer on her head and legs and a topknot.

However this last time I had her cut shorter 1/2 - 3/4" length, legs cut short on the top and left long on the bottom. I really like this look on her, DH laughed when he first saw it and said she had bell bottoms on. I don't have a picture uploaded with her new look, but I like it best so far out of everything I've tried on her.
Yogi has georgous hair and I hate to cut it, but must in the summer time as it gets entirely too hot for him otherwise. I have him cut to 3/4" and it's layered some from top to bottom. Again, I leave his legs and head a little longer and leave a topknot on him. I get his tummy and chest shaved close to help with the cooling factor. It's was hysterical the first time we walked out of the groomers and the wind rippled through his hair and tickled his just freed 'man bits'.

His head went up a bit higher and his tail popped up straight and he strutted over to the car.
