TW; There is NO stopping Nukka the Killer.

There was a time when I was harvesting rabbits and gave her a whole rabbit skull, fresh and tasty. She dropped it for twenty minutes to go run after a chipmunk that escaped under the fence. Calling her, waving the rabbit head, did nothing. She just wanted the living thing.
Now, she does respect my paltry deer netting fence. As does Persy, the Big Dog... They even generally respect the door when it's open... I trained them to NEVER go into the chicken pen EVER. (With Tender, it was Tender that walked out of the pen, not the dogs going in. But the moment that barrier isn't there Nukka becomes a vicious destroyer of all things small and not canine. She has NO recall when there's an animal on the loose. So there's not many options. She can be leashed for life or we could get a shock collar. :| I think she'd prefer being allowed to run still. She just needs a lesson.
I feel like she's a very smart dog and I am confident she will pick it up. At least in regards to MY animals.
