Recent Agression In 8 Month Old Mini
We have recently moved to Philadelphia and my 8 month old male Mini Aussie has gotten more and more aggressive towards other dogs when on a leash.
He was exposed to dogs of all sizes when he was very young and would play for hours in the dog park.
But now we are extremely embarrassed by his recent behavior (excessive barking) and want to know what could cause this all of a sudden!?
Any ideas and/or suggestions of how to get our old dog-friendly pup back?
