I've never been in the position before and I know every dog is different, but wondering if some of you can share your experiences. I had two dogs. The elder dog recently passed away. Now I have only one dog. This dog has lived with the elder dog for 8 years, since she was a 6 week old pup. She doesn't know life any other way. I'm really not sure what to expect in terms to her adapting to being the only dog, or being without her big sister/mama figure dog, etc. They were buddies and spent virtually 24 hours a day together the last 8 years. I'm not entirely sure she gets it yet, though she has been having us open the front door quite a bit and then not going outside, like she wants us to let the other dog back inside or something.
