Just like with anything else, we all have preferences and dogs are no exception. What is a breed of dog you wouldn't own under any circumstances? No big explanation is needed . I personally don't have any dog that I dislike ,but I probably wouldn't have anything of the toy variety. I don't know though, I've said that I would never get a cat ,but once I met my husband, I love them as much I do dogs. If I met any dog who needed help, I would help it.
