Foxy and Jack Playing

I had Jack (shih tzu / cockapoo mix) first and found he was a bit much for me and the rest of the other dogs in the house. While finding a home for Jack I got Foxy (chihuahua mix). They overlapped about four days and played with each other all of the time. The play mostly consisted of Jack pummeling Foxy. Jack is with a new family that has grade school age children and they are loving him. I only had him two weeks, but he was just the cutest, smartest dog I'd ever had.
