Our two dogs have been together their entire lives. They are both 13-14. Our border collie just died, leaving the little dog alone. This little dog was very dependent on the Border Collie and hates to be alone. I'm wondering if we introduced another dog into the scenario, how that would work. It would probably be a slightly older, retriever type dog around 2-3 years old. (We believe in rescue.) Part of the reason we want another dog is also for my son, who loves to play and interact with them, and the cockapoo is not really a "play" type dog. Just wondering what others experiences have been. The cockapoo is very healthy, and being a small dog, could conceivably live another 4-5 years. My son is 11 and the perfect age to have a dog for a buddy.
