Hello. 6 years ago my mother lost almost all of her vision due to complications with grave's disease. She has very limited (around 5%) vision in her peripheral of one eye, the other has zero vision. About a year after losing her sight she went to a prestigious school in California and trained and received a beautiful service dog. Since then the dogs training and discipline have been rapidly declining. She started off walking and taking the dog everywhere and is was very well behaved.
Over the years she has become less active and interested in going places on her own, the dogs behavior inside the the house has completely fallen apart, it jumps on people, nips people, destroys things in the house. When it is "working" it is pulling her around, sniffing/scrounging for food on the floor in public areas, barking at other dogs. She will not listen to any of my siblings criticism regarding the dog or its behavior... and we are all afraid it is going to get her hurt. I was wondering if any of you had some advise?
