We have two dogs at the moment a five year old Cockapoo and a 9 month old Shih Tzu. The puppy loves to rough house with the Cockapoo, but she can only take so much and she is done. We were flirting with the idea of maybe getting another Shih Tzu to accommodate the puppy and give our old girl a break. We just love the Shih Tzu, I would have ten of them if I could. So from the title, is 3 dogs to many? I would like to hear from the multiple dog owners.
