My friend has a 6 month old Rottweiler shepard mix looks like a rott.. anyways the dog is loving to her and family but aggressive to other dogs and people the vet told her sometimes they are wired wrong...and she may have to put her down....they put her on paxil and amitriptilne ...and I guess when the dog is left alone in the house is destructive...do you ladies have any suggestions for her she hired a trainer and still no changes....are there any types of rescues that would take the dog instead of her having to put the dog down? she is heartbroken and doesn't know what to do ...any suggestions??
