Behavor change after a move.

I am a little confused by your post - but it sounds to me, like Ginger's routine has been drastically altered and she is very anxious...  This, without any signs of aggression, doesn't sound to me like she might bite someone (but again, I am just trying to figure out waht is going on based on your post, and I am no expert...).  What kind of behaviors started when your other dog died?  Is it the same type of behavior?  Is it only when Ginger is alone?  Maybe Ginger is anxious about being left totally alone, particularly in this new place?  I think a little more info. might help us figure out what is going one here...  Welcome to the forum!!

It sounds as though Ginger is very stressed at being left alone in a strange place.  It is hard for some dogs to transition, plus she may have relied strongly on the Shepherd that is now gone.  It might help for your son to consult a good behaviorist, since it seems like Ginger is experiencing separation anxiety.  This is not a dog that would do well in a shelter environment IMO.  The IAABC website may list a behaviorist near you.
A good reference to get started with: "I'll Be Home Soon - How to Prevent and Treat Separation Anxiety" by Patricia McConnell.
Sometimes, it helps to leave the dog with a stuffed Kong or Buster Cube with kibble in it, since the damage usually occurs in the first 20 minutes the owner is gone.
This poor girl needs some help, not to be dumped.  I hope your son will seek professional help for this dog.

HI, some more information on Ginger.  Wolf (the shepard) passed away about 2  years ago.  Untill then she had never lived alone. After his passing she would not eat, she took to knocking over the trash, she would walk the house looking ofr him and cry a lot. We understood that she was morning his passing just like human would and my son understood this. and he would secure the trash he went and got a doggy door so she could go outside when she wanted, he took her for more rides in the  truck , he got her now toys and after a while she got back to a more normal dog . We also understand that she does not know this new house and the sounds are different and the smells are all different.  We also understand that there will be some transition time for her to adjust to the new home (townhouse now not a single family home) My son went and got her a crate. Now mind you he did not just toss her in the crate and call it a day. he spent the time letting her sniff it. he put her bed in there, then he put her in it but did not close the door.  praised the heck out of her.  Put her in again and closed the door. let her out and praised her like heck. Did this a little longer every time, eventually he left the room,  same rutine let her out praise praise. he left the appartment staiyed outside the door again let he out praise ... you get the picture.  We are not just going to get rid of her, we will work with her as best as we can and i am 900 miles away not much other then  advise that i can give.     As for her bitting. Well when we lived in a 2 family house she had free access to the yard. If my mom came to see me , she would be happy to see her wag the tail race up the stairs, and sit infront of the door and show how white her teeth were... Even to my mom who she knew all her life.  so could she bit ...  any ones guess.

Why doesn't your son get another smaller male dog for her companionship ?
 
Does he leave the TV or radio on for her?
