Yes they are telling you to get rid of the dog, just like my mom does anytime I have her watch my dog that has severe separation anxiety
She doesn't destroy anything per say, but will throw trash all over the house, and dump over her water bucket. It doesn't matter if I am gone days, 5 hours, or 5 minutes she will dump her water. . . I gotta make sure I don't have any floor damage when I move out of this place.
You can check car-part.com that will list quite a few places you can order a used one from a salvage yard
But never blame the dog, it's usually not their fault, my dog was a rescue, she was beat and battered by her old owners, and left alone and locked in a kennel for days, so she misses me when I am gone
