We have learned that the best thing with our Basenji is lots of rawhides, and not little ones (those are gone too soon in our house) but big braided ones. It may help with the chewing!
It isn't that they are necessarily outside dogs…they are just incredibly "barky" dogs so they get sent outside a lot. Any and ever time anyone is out in our backyard, their dog barks and barks and bark for-ev-er until we go inside. Those dogs may drive us crazy, but they are still animals and we still feel bad for them 😞
