You have already one little dog? Two little dogs equal one medium dog. You already have a medium dog and a big dog? So, one plus one, plus one plus one equals 3. You'll really only still have 3 dogs. This is true. I had my Lab, my Doberman and two Chihuahuas fairly recently. Then I had my Doberman, Toker, (a pit/GSD mix, I think) and my two Chihuahuas. Now, just Toker and the two Chis. Either way, it's 3 dogs or less to me. LOL. The Chis just go together, like a pair. "Pair" is singular. :rofl1: So if you want this pup, go for it. It probably won't make a huge difference once the pup is civilized. I like the foster idea too if you're not sure.
