If your dogs are destructive or suffer from separation anxiety, could it be the way you leave them?  When you give them treats and “baby talk” to them before you leave, do you notice their tails wagging in excitement and enjoying all of the affection and attention you are giving them?  Do you throw their ball a few times for a game of fetch and then lock the door behind you?

You could be getting your dog in an excited state of mind and then leaving them when their energy is so high.

Try calmly giving a quick pat on the head and saying goodbye.  Don’t make your process of leaving feel like a big going away party every time.
