Sorry if this is long, I feel the need to share the story to get it out and help process. I literally feel sick to my stomach from watching my puppy kill a rabbit right in front of me. My 11-month old cairn terrier mix puppy Fitz has been chasing rabbits out of our fenced backyard for the last few months. I never thought he'd actually catch one as they go so fast and get out at various points under the fence that Fitz can't go. But today he was out in the backyard and he caught one. It was horrific, the rabbit starts shrieking this awful, loud cry/scream. Fitz has firm mouthful of the backend of the rabbit shaking it back and forth with blood and rabbit bits going all over. I tried to get Fitz to leave him/come to me but wouldn't you know he completely ignored everything (despite being very good in normal situations). I tried luring him with several of his favorite things but he wasn't interested. I finally got him to let go of the rabbit by whacking him with a broom but then he was just running around it barking and occasionally going back and trying to bite the rabbit again. I finally chased him away from the rabbit and into the screen porch where I closed the door. He was covered in blood all down his front and so proud of himself. I grabbed him with a towel and put him in the shower. It took forever to get the blood out of his fur. I then left him to dry off and he started shaking uncontrollably. I think because he knew I was mad at him. So i took pity on him and wrapped him up in a towel and held him a bit and the shaking stopped. But i cannot figure out what to do about the dead rabbit - I am so grossed out by the idea of even looking at it. Unfortunately I have no boyfriend/husband/friend that is not grossed out by these things to help me dispose of it. But that's kind of a side rant. My real question is should I be worried about my dog at all? I know its natural for dogs to hunt but the viciousness that he displayed and how much he enjoyed torturing the rabbit freaked me out. Should I be worried about a violent streak? I am afraid to let him loose in the fenced backyard because of something like that happening again. Also, I have read that rabbits can carry diseases and he definitely got a lot of the rabbits blood in his mouth - do i need to take him to the vet?
