The only time Red, my pug was mean was when he got treats and he didnt want the other dog near his treats. Now he barks and growls and bites my labs mouth whenever i put more food into the dish or when they get treats and when we put the dogs in their room at night sometimes red attacks my lab. What the heck has gotten into him. I use a spray bottle of water, most of the time that works but why is he doing this? Ive always had to seperate them when i give them wet food cuz red will attack any animal dog or cat that comes close to his food. Now hes like a lil devil when it comes to their food bowl, they share the same bowl.
