Cannoli

We received Cannoli from a friend who couldn't keep him anymore. He lived with him and his 2 daughters (around 8 years old), however was left outside most of the time. We took him in, got him all his correct vaccinations and fixed. He always had food aggression. He has always tried showing dominance around our male dog by humping and bossing him around. He more recently will attack him at any time he sees him.
