It was one of our family dogs, and we all loved her dearly. I was playing on the couch and fell off, landing on her tail and hurting her. She instictually snapped and it resulted in, unfortunately, the worst possible outcome (it is shitty, but it is one of my first well formed memories). Despite it being a freak one off, my parents couldn't feel safe given what happened and rehomed her to a family friend who didn't have children. She lived a long happy life and my dad still got to see her regularly, as he was heartbroken that he had to make this choice. I personally don't think my parents letting their kid play around the family dog, one that they had since before I was born, should have their faces readjusted.
