Kiwi has the muscle memory of a rock.
The 'wi has gone from impossible to train, to OMG I LOVE YOU WHAT DO YOU WANT like a ball-sick labrador after you've been gone all day. These are also peppered with the occasional fit of OMG DON'T BEAT ME. Which occur at complete random, usually when I am not even interacting with her. Take last night for example, I was putting my phone on the table and whatever motion that involved gave her the impression I was about to gut her and serve her raw. No amount of anything would "fix" her. So I eventually gave up. Today shes my buddy again. I think a wire is loose in there. If she kills me in my sleep, it'll all make sense.
Anyway, back to rock muscles. I have been trying to convince her to "sit pretty" for about a month straight now. Its a behavior I have been capturing and shaping, and since its not perfect, there's no lure/hand motion/cue for it yet. She just does it at random when she feels its time for her and I to party. Which is many times a day.
She would only hold it for a split second, before either dropping back into a sit, or doin' som' zoomies-ish motion, or standing up completely like a weirdo. Paws high like a 6 year old kid stands when mom is about to put a shirt on them. After selective rewards for over a month now, shes not making any progress in the duration department. So my conclusion is simply that there are no abs-o-steel in there, and those muscles instead are in her ridiculously muscular pit bull beef legs that she has, despite the only exercise she gets being nap marathons.
Chili, on the other hand. Has decided to once again make all the other dogs look like chumps, and just randomly one day decided to basically stand in front of the 'wi as it flopped around, and do the trick with 110% perfection. He even held it until I said "OK". Hes like that gifted kid in high school that really should be the one beat up, vs the people that have to actually put in effort to get things. Its so sad, hes like "like this mom?" with a pathetic expression. While the others just emanate a long, low durrrrrr sound that fills the room.
I think kiwi is debating stuffing him in his locker and eating his homework.
