Well, a casual stroll for a couple of blocks probably wouldn't hurt, but as you said, it's not going to do much. If she was really exercising this dog like it needs, AND she cut calories, she could definitely see results.  That takes effort, though, and you know how that goes. The fact that she is smiling about making this poor dog fat makes my blood boil.  I hate animal abuse in any form.  This is certainly abuse, any way you look at it.  Grrr.  I'm going to hug my healthy weight, active dogs at lunch today.
