Our experience with past pets is that pets bond with each other. When our big boy cat (who we cherished) died, our mini-dachshund was very affected. She missed him. And while she liked us, her relationship to the cat was closer.
Our little yorkie girl has only known us and is bonded to us like super glue. We have deliberately caused her to form other close relationships in case we can't be with her. When she's with other dogs she recognizes them as another animal but she doesn't know how to play. I think she would be confused and sad if we brought another dog into the house.
Given those experiences, I think it depends on their personality, their experience, and the skill of the family to bring in other animals in a way that creates a bond. If you're pup seems sad and lonely and you want another pet, I'd say GO FOR IT! |
