How horrible!!! Prayers going her way.

My parents' rescued dog had cancer and it finally affected his brain. He went into a rage and attacked my father. The attack was a complete shock. You just don't know what might happen. Even if the dog was not a rescue, if it was a dog you had owned since puppyhood, the dog could develop cancer and the cancer could cause bizarre behavior (especially if it hits the brain or liver and the toxins build up in the brain).

My heart goes out to this poor woman.
