I had a Border Collie that showed up in the dead of winter many years ago. Efforts to find an owner were unsuccessful. My kids were young and pleaded to keep her which we did. She was a wonderful dog. She has since passed away and I would like to get another BC. I have nothing against responsible breeding but would prefer to get a dog from a rescue. I found a dog at a shelter (not a breed specific rescue) that was listed as a BC. I am in another state but from the pictures she looks small. When I asked about it they said the vet that had brought her to the shelter had called her a miniature BC. I know this isn't an official breed. When I asked for clarification of if she was a mini or just on the small side of the bred range they said she was just a small BC. I am told she stands 16" tall at the shoulders and in a sitting position the top of her head is 23". She has the BC look. She was originally listed as a pure bred. Is this possible with her shorter height? I googled mini BC's I found an old post on this site about how all mini BC's have problems. I have rescued feral cats before and am not adverse to dealing with issues but would like to know what I may be getting into. Can someone tell me what I need to know about mini BC's.
