A guy in Los Angeles recently tried to break a world record by walking 45 dogs at once.  But it was harder than he thought.  He had to go around a track three times.  But first they got tangled, and then the leash was cutting off the circulation to his hand.

Then some of the dogs started fighting, and the owners got nervous.  So he had to quit.  A guy in Pittsburgh still holds the record at 35 dogs.
