Wow! Thanks everyone for the great advice and encouragement. I just got home from work and thought I might have gotten 1 or 2 replies. But there are 9!
I had asked one of the groomers at PetSmart where I take Tink, 'cause she was grooming a beautiful little Yorkie and she
smirked at me and said, "You can't grow out a mutt's hair. They aren't meant to have pretty hair". I didn't have Tink with me, so she didn't see her pretty black hair. But that made me so mad I swore I would grow her hair out if it killed me.
Then I thought maybe I'd better get some expert advice from people who would probably be gracious with their replies even if I was way out in left field.
I know Tink is a "mutt" (I prefer "mix" it sounds nicer). But she didn't have to be so sassy about it. Sniff sniff.
So, I think the consensus it to give it a try and see what it looks like when it gets a little longer. It grew quite a lot in 3 months so maybe by the end of summer I'll be able to tell.
Thanks for the advice everyone. And thanks for all the compliments on my little Tinkerbelle (aka Tinkerbrat)
