Differences in personality

I thawed what was left of the deer carcasses I was given this past season.  I decided to toss them into the back yard and let the dogs have some chew time.  I found it very interesting to watch them choose a section and go about eating it.  Garion and Lena are very utilitarian, they dragged their sections of ribs away from the pile and proceeded to demolish them.  Lena ate her section in a very organized manner, completely.  Garion ate about 3/4 of two sections, I think they picked up to much grass and debris so he lost interest.  Bentley, I don't what to think of him.  He might be a bit slow, he couldn't figure out what to do with the remaining ribs, the spine was too much for him and the pelvis he didn't even look at.  He picked here, sniffed there and then tried to negotiate a scapula.  It seemed to be too much for him, he ended up eating most of one that Lena took a chunk out of.  Goliath, my mostly toothless old man was let out last, I did NOT want him going after what Lena had.  He went straight to a huge section of ribs, stood in the center and started tearing at it.  He is relentless, and completely unintimidated by something that is bigger than him.  He will be left alone out there for quite a while, it's hard work for him to get anything off the bone since he has no front teeth and only has maybe 4 molars left.  I doesn't stop him!!  I have no doubt that Lena would survive just fine if she went out hunting, she has proven that when I left a whole frozen rabbit out in the yard.  It took her 3 days to figure out exactly what to do but when she did she ate the entire thing, all she left behind was the stomach and entrails.  If Garion ate rabbit I'm certain the same would hold true for him.  Bentley would have no idea what to do, he had a chance at it, even after I cut it open he couldn't figure out how to get past the fur.
