I was not going to jump into this thread because it brought back a flood of hurtful memories.
I had a dog named bear that I got from a no kill shelter, he was 5 years old, he was at the shelter for 3 1/2 years of his life in a garage with only 1 other dog as company.
When I took him out, that moment I knew he would be a lot of work, as he lunged in fear at everything that moved. He was great with me, great with old people, but anything, and anybody else you could see the fear in his eyes every time he lunged.
I did trainers, I did behaviorists for 3 years. Finally the day came where he could no longer go outside. Only time he felt safe was when the lights were off, blinds , windows closed and on my lap.
Then we went for a very early walk, away from cars and people. Then a truck came, he then threw me in front of a large truck and almost killed both of us.
I called my vet, spoke to her for hours, I did all that could be done to try to save this dog. I then made the hardest decision of my life and had him put down.
I just want to let everyone know, I do not know what the OP has tried to do, but not every dog can or should be saved from the demons in their heads.
Now I sit and cry
RIP Bear
