Crystal is a black and white 3 to 4 month old mixed breed puppy weighing in at 15 pounds. Best breed guess is Blue Heeler mix. She is a little sweetie, but is all puppy so does nip especially at hands. Her favorite thing is to have a chew toy in her month, probably because she is still teething. She is house and crate trained. She is friendly with people and dogs. Cats are unknown at this time.
