Harley has taken up something and I don't really know what to do. He keeps flipping the dog house over and he is eating the wood off of the bottom of it. I am quite concerned as I just came in from feeding this morning and I actually saw him take a bite. I am getting ready to go back out and move the dog house and dog (who protects my horses) to a part of the yard where he cannot get to it to eat it. Should I talk to the vet or is this normal?
