Our book, BARKOPAEDIA: The Canine Book of Knowledge is on its way to Champ & Major Biden at the White House!
There are a few chapters for dogs that suffer from stress, anxiety and other emotional issues that Major may benefit from. Major is a rescue which can sometimes cause lots of unresolved issues. Also, he is a German Shepherd - (one of my favorite breeds!) and GSDs are very protective of their owners and territory. Being in a new environment may have triggered a few of those bites! Sending love to them both.
I am smitten with those magnificent bat ears.
