A few years ago while on the chain the neighbor dog, 1/2 shepard 1/2 wolf came and attacked DOG and bit her eye and she may be blind or at least was for a few years, the color has restored somewhat but at nighttime it still reflects wrong. Later DOG got into a fight with the same HUGE dog and threw it into our pond and got on top of it and was killing it, sadly the owner came over the hill and I had to call DOG off. This same dog is younger and looks much older now and partially crippled already, DOG will our live the monster dog by many years. !/2 wolf dogs have no place as pets, especially when they seek to kill other dogs.
