Jim,
I thought this was a family site. Gives special meaning to the term "joined at the hip".

We had two Rotties that came to us from New Orleans a few years back after Katrina and, like these two, they couldn't be separated. They were both 8 or 9 and the girl was the stronger of the two. When I tried to take her for a walk by herself, the boy just whined so I only walked them together.

Fortunately, the folks who adopted them took them both. Let's hope you have similar good fortune.

Jim
