I see what your saying. Begging is "cute" as a trick. But, IMO, NOT as begging for food. Barking amd crying for food is REALLY annoying. I mean puppies can be trained from an early age to stop. So, I think the people should try a little harder to train them. Begging is easily prevented. But the major problem is it is very easily caused. People feel bad for the dogs so they give them food. I just can't stand it. It's really annoying unless taught on command.
