We had a rescue from a neighbor who was fostering him. We were told he had been abused, possibly neglected and had been in 3 or 4 homes prior at only 18 months old. Lab/Shepherd/Pit mix. I would take him and our Jack Russell in the car often when running errands. But the first 6 months or so, he didn't want to go in the car and would puke every time. Then he got better and even wanted to go in the car every time I went anywhere. I had realized his fear was of being rejected & dropped off again. He was always so gentlemanly (no other way to describe it) in his behavior,
He turned out to be the best chicken herder ever without hurting them. When they would get out of their area, he'd chase them down, then hold them with his paw until I could get there and put them back. Most loveable and loyal dog ever......except for men. He didn't like them and it took awhile before he'd let my husband in the house and later they became best friends too.
It's been almost 2 years now and I still miss him
