 So one of the important things to understand if you happen to be dealing with one of the dogs suffering with either the abandonment issues or the separation anxiety is try not to make a big deal out of leaving. Try just going out the front door, coming in the back door, going out the back door, coming in the front door. Go sit in your car for five minutes and then come back into the house. As long as the dog starts to understand that when you leave, you're always going to come back.
