My daughter had a couple of ducks that all the cats were terrified of...the horses didn’t much care for the ducks, but when one of the horses had to go to U of M for a major problem, the remaining horse let the ducks in the arena...She was lonesome and cozy up to them...it was funny, she needed some friends and would follow them around when they came into her area.....
We have just had a strange thing happen on our ranch. Someone dumped 2 young dogs there. They would not even come near us but we put out food and water bowls for them. After about 2 months one of the dogs disappeared. The remaining dog has taken up with a bull out in the pasture and stays very close to him all the time. The dog still comes up to eat when we are not there and goes back to the bull.
