YoYo is the smallest in her pack, but learned quickly to wiggle out from under the churning puppy pile. She likes to hide behind the door and dart in an out like a yoyo to ambush each puppy individually. She runs to greet her people, and wiggles her butt in anticipation of being picked up. YoYo is charting to weigh 5-1/2 lbs as an adult. We chose with this litter not to dock (cut off) their tails, a practice now banned in Europe and many other countries. Our puppies proudly wag their beautiful natural tails. Yoyo is CKC registered, vet checked, and vaccinated.
