Anywone esperienced anything similar??
Not sure if this question would go in the General Behavior Groups, but this may be more appropriate. I have a 18 month old male GSD who over the past 10 months or so has nearly ripped the bark off every tree in our back yard chasing squirrells. Once he chases a squirrell up the tree, he literally jumps and bites the tree pulling off huge strips of bark. I'm assuming that its' over agression at chasing these critters that's causing him to bite at the tree. Every tree in our backyard is missing bark with series teeth gouges into the tree itself all the way around for several feet up the tree, regardless of what kind of tree it is. Otherwise, this is the most laid back, kid friendly, visitor friendly dog one could ever have. He's almost too laid back. This just occurs when he goes outside and on the prowl for squirrells. This is gonna wind up costing me several thousand in dental work from damaged gums and teeth, not to mention beautiful hardwood trees that I may possibly loose. The vet when initially asked said this is a working dog and he's looking for "work". He advised us to build an obstacle course to keep his mind busy. If I posted pictures of the trees on here, it would blow your mind. This is also a championship bloodline GSD. My dog has not been neutered and wanted to get imput if this might help any other helpful recommendations. Thanks
