She sounds like she's doing really well Clay ( as are you!). Elfpup has sit, wait, down, to me ( his recall) and "give paw" down pat. I did teach the last because my previous dog hated anyone touching his paws which made foot inspections at the vet or groomer a trial for all concerned. I don't want that to happen again.
Stay, leave, fetch and drop are all works in progress. He does know what he's meant to do but whether he does it depends on whether he is feeling inclined to! I do 5 minute sessions with him several times a day with the new ones he's learning mixed in with the ones he knows. Hi5 is the next on the "fun" list. He enjoys the sessions and we play.
For "down" yesterday I had him chasing me around the garden with a down command at each end and then at random. He had a great time, we both got some exercise and the command got used and obeyed in an exciting environment rather than in a nice quiet and distraction free room.
Could you use part of her food allowance as rewards rather than treats? You'll know then that she is getting what she needs.
Elfpup is glorying in his new diet. The switch to wet food is really paying off. The poos ( despite the mouse!) have returned to normal and the "full tummy" feeling that he didn't get with the kibble means he takes a proper nap after a meal and settles well in the evening without all the overtired biteyness.
