Sympathetic Limping?

[sandgrubber]

I had a very sad pup a few months back. Very severe OCD seems to have come from nowhere and HD seemed to be on the way. On veterinary advice she was pts at around six months. Her great grandmother, who seemed quite fond of the pup, took on a severe front right limp while the pup was in decline. I put the old girl through quite a bit of therapy with absolutely no effect. After the pup was pts her limp has gone away.

I know dogs can "adopt" limps to get attention . . . but is it possible that the old girl was limping out of some sort of sympathy.
