Yeah, I am very familiar with Bella's Doggy Boutique on FB. She makes nice things but I've never ordered.
My point is - that name is pretty well known already and has customers. I like Dawn's Doggy Designs.
If it is already taken on FB, try spelling it a little different. (Doggie) Or Dawn's Doggy Boutique (instead of Designs)..
Can't wait to have another YT vendor to buy from
