I have a 2 year old male Border Collie cross. Bjorn is an exceptional dog, he’s a bit stubborn but he’s overall an amazing dog. He will work cattle but it’s not exactly something he likes to do. He’s house broke but he’s spent most of his time outside. He gets along well with other dogs but I have to say he is food aggressive. The reason I’m getting rid of him is because he’s very mean to one of my male dogs, but only him. He’s best friends with my father’s Australian Shepherd which is also an intact male.
