Back in the 80's we had two Yorkies. A little boy (toy size) named Squirt and a BIG girl (porkshire size) named Spring. We only had one litter before getting them both fixed as she only had one puppy that was even bigger than her! Squirt got his back bone snapped in two spots while on leash in the road by a wandering pit bull. Squirt got run over in front of the house a few months later, I always said it was suicide from a broken heart over missing Squirt. Yorkies are fun dogs, it's the terrier in them.
