Today I took Wynstan around the block for a walk for the first time (we normally go to the park.) He started barking, there were no dogs around. My only guess is that he barks at fire hydrants.
I confirmed it during our second walk of the day, this time he just growled at the first one, but he went absolutely crazy at the next one.
He also barks at inflated basketballs, rose bushes, the box of gun cleaning supplies, and several other items.
Just wonder if anyone else has a puppy that does the same thing?
