Btw,
At first I didn't think it was the same dog. At first glance. But when you really put the two together, I do think it's the same dog. One she is healthier, younger and cleaner in. The hair recession on the nose is pretty common with the type of coat she has, and it wouldn't have been present in her younger photos.
But the markings match up and the color has just changed, as they all do.
It's very likely that the three dogs in the photos you posted are in fact, the same dog. |
