Lucy is coming along slowly but steadily in marker training.
We now are working on sitting and waiting for her food to touch the ground and me releasing her. Her sit for that (which needs a reminder at times) is with a foot held up. Submissive gesture I am sure will fade when she trusts she will get the food eventually.

Her sit on command and wait there is an iffy thing right now. The longest she can sit without moving is 4 seconds and then she explodes to the left, right, backwards, forwards, up and down---all at the same time!
While it is entertaining to watch, I am trying to fade that out. I am approximately 2 feet in front of her while trying to keep the sit. No video I own shows a dog who just can't keep from exploding from excitement or frustration.
And, since Lucy has had severe neglect and 'mistreatment' in the past, I am reluctant to use any corrections until she knows for a fact that she must sit and be still.

If I am missing a step let me know. I am working on extending a command while being close, and extending my distance but keeping it a short command.

And, my Hambone -- Husky mix -- is doing quite well in all areas-physically and behaviorally! (sticking a blurb in here for vet checkups for behaviors issues and for the terrific Leerburg training methods on this board!)

I taught mine to sit and wait for me to set the bowl down by putting them in a sit and starting to bend over, if they break the sit I straighten back up and tell them to sit again.
They get the picture pretty quickly.

Teaching Yote to sit for longer periods of time was done separately with the clicker, starting at 2 seconds then moving to 4 and so on.
We are up to 90 seconds right now before he spazzes out.

I was just thinking more about this and it might not be a good idea with Lucy since she might have doubts about the actuality of getting the food.

I would probably use a yummy treat instead.

Took your advice. I have had Lucy long enough she knows she gets fed. I did a mental inventory of her health problems and most are fixed permanently or to the point, she can now pay attention and be expected to obey.

She sits but still acts stupid, so I changed it up. She now must down for her food, and I do what you did. She now downs and stays until I tell her she can get up and eat. She downs and stays (in the house) while I walk away from her a couple of feet and come back. The spastic sit...still working it but it is coming along.

She is much calmer now that she has a job to do...obey a command before eating, shut up and don't bark while the food is being prepped. That's a tough one for her. She sounds like a braying donkey with laryngitis! LOL. But, no barking.
Obedience expectations do make a difference! AND, being healthy make a difference in attention span and will to work.
THanks!
