My goose was attacked by a dog. The dog grabbed the goose around the middle and just held it. No violent shaking, I got water hose sprayed dog and he dropped goose which ran into a fence and then I picked him up. He is very tame and i have picked him up before. His back leg is sticking straight out and it will not move. His other leg will move but he can't stand. There are no visible signs of injury, no tooth marks or puncture wounds. I have kept him quite for the last couple of days with no change. He will eat and drink if i put food and water in front of him. i hope someone knows what might have happened. I can't have a paralized goose that needs constant care to survive.
