Please don't give up on the rescue route. I got my Annie (Maltese) at the age of about six months from a small breed rescue and she was a total diamond in the rough and I mean rough. lol She's just beautiful and perfect now - at least to me anyways.
Also, the last time I was at our local SPCA to pull a little Maltese there were many fullbred small breed puppies waiting on a furever home with not much time left to find one.
Our local shelter used to have nothing but pitbulls, but so many are turning in their dogs now due to the economy - all breeds and sizes. So sad.
Or, take your time and save the money to purchase from a reputable breeder. If there are shows in your area you can go to those and meet the breeders who are showing and you might find the perfect breeder with the perfect pup and the price might not be as high as you think it might be for a pet quality pup. I was looking into purchasing my next Malt from a particular show breeder when Ruby, my new rescue Yorkie, came into my life. I was sure my next would be a puppy from a reputable show breeder or a retiree from same. Same thing happened when I got my Annie from rescue. Seems to be a running theme around here. LOL Now, I know for sure where my heart lies.
Just, please make sure whatever route you take that you aren't supporting a back yard breeder, puppy mill, or broker. Don't believe the "we only purchase from local mom and pop breeders" line. That's what all the pet stores around here say. Good luck in your search.
