It depends, because the definitions for the sizes differ a lot. For some, a 50 - 60 pound dog is medium sized, but to others it is large.

My pups, full grown, will be about 60 pounds. HOWEVER I haven't had them weighed in awhile so I don't know lol

I think a more accurate poll would have choices like
0 - 10 pounds
11 - 25
25 - 60

or something like that
