I had to lift my old 65 lb Lab a lot in her last year, and it was tough (she did lose weight though as she lost muscle). 11 lb Buddy on the other hand, is easy to lift.This is unfortunately very true, at our local humane society every dog seems to be 44+ pounds! Nobody apparently wants them, very sad.
For practical reasons, and because I'm getting old, I cannot do a big dog because I won't be able to carry it around if need be - I had to do a lot of that with Toby toward the end. So that's why I'm looking for a smaller dog now, even smaller than Toby's 26 pounds.
I don't know how easy it is for you to get to local shelters, but they usually have more small dogs than they list on their websites because they move so fast. When we found Buddy (looking for another Lab), he had been there for two days, but wasn't on the website (he was owner surrender so he didn't have a waiting period). They put him on the website while we were doing the paperwork (IT people at a different location).
