I dont understand what his problem is. He is very bad sometimes. I have found that using the crate on a regular basis and being firm helped my greyhound adjust to my schedule. I placed a radio nearby to sooth her. I feed the dogs and cats at separate times so the dogs do not eat the cat food.
All dogs love cat food.
If the food is not eated within a short time, I pick it up and they will eat the next day. Do not give treats unless it is a dog biscuit. All dogs will beg if you let them. Dogs as children require direction, consistency, and dicipline. Remember that you are the boss, not them.
