Dog Reacclimation

Question
My daughter owns and loves a young mixed-breed female neutered dog.  The dog is accustomed to living, working and sleeping with my daughter.  Recently my daughter moved in with her boyfriend in his home with his very gentle male malamute.

At first my daughter's dog seemed to be handling being in the "dog room" at night and when parents were away with the malamute, but in the last few times they were away started chewing steps and windowsills.  My daughter put her in the crate that she used to like to be in, but the dog frantically tries to get out and rubs her face raw in doing so.  She  tried putting the other dog in another room while they were away, but that doesn't help.  

My daughter and her boyfriend are at odds with what to do.  They can't let her chew the house up and don't want to see her hurt herself while confined to the crate.

Please Help!  

Answer
This is a clear case of separation anxiety (the determining criteria being the self injury and destruction at areas of egress), and is difficult, but not impossible, to deal with.  Unfortunately, it usually requires protracted behavior modification work, coupled with medication for some dogs.  She should contact a behaviorist for assistance, or even her own veterinarian who can prescribe medication to help the dog cope while learning new strategies.  She can get started by reading "I'll Be Home Soon" by Patricia McConnell.  The dog does not care about the presence of the other dog - all she is trying to do is get to your daughter, as that's her only security.  Unfortunately, your daughter keeping the dog with her constantly probably contributed to this in a dog that already had the tendency.  Good luck.
