Cooper looks cute and he sure will appreciate his summer cut in the heat. Great that you have this attitude, as long as Cooper is safe and he is not bothered (is he?) you are okay with it.
I love to look at hair style magazines, pick a style, show it to my hairdresser, get it done, come home and am soooo disappointed because I don't look at all as on the pic....

. Guess that's the same with Yorkie cuts?
I will make an appointment for Merlin next week and although I have printed some styles I'm sure he will look different in real...lol...unique.
