LONG.......
I know this will not make you feel any better,
but Kito did nothing wrong in Doggie terms.
I bet if you ask your vet about it when Abbey gets
her stiches out, I bet he will say he has seen
this happen so many times before when it
comes to dogs fighting over food and bones etc.
Kito is acting out from instinct.
This is why I do not allow our dogs to have bones
or feed them when I am not their to watch.
(one examples, and I do have more)
Sheba and Rocky 2 years ago almost had WW3 over
a butcher bones. Luckly Sheba is well trained and
I was able to grab/jump on Rocky and tell Sheba to keep away.
I am sure Rocky would have hurt her since they
are close in size and pecking order.)
After that, NO meaty Butcher bones period.
(steril bones they will not fight over)

What I am trying to say, we learn from our mistakes.
Keep anything worth fighting over away from the
dogs when you are not able to supervise.
