We had a bulldog when we were growing up that looked just like Petey from The Little Rascals. I couldn't count how many rabbits that dog ate.
My grandparents next door neighbors gave my brother, sister, and myself each a baby rabbit one day. My grandfather built a cage for them and we took them home. When I went out to feed them the next day, the cage door was wide open and the last little rabbit was jumping out of the cage into our bulldog's awaiting mouth. It didn't bother me that much, but my brother and sister were very upset when they went out to feed their rabbits and they were nowhere to be found.
Our neighbeor that lived behind us had a full grown rabbit that he would allow to hop around his back yard all the time. I told him to keep an eye on the rabbit and to not let it get out of his back yard and into ours as our bulldog loved rabbits. We were swimming in our pool one day and we heard our bulldog start barking and running around the back yard. We looked through the fence and saw her chasing our neighbor's rabbit around the yard. We went out and tried to catch the bulldog and/or the rabbit. Well the bulldog caught the rabbit before we could catch either. To this day I can still hear the sound of the rabbit's skull being crushed. That bothered me more than our rabbits getting killed.
