Great great question, Kim, and hopefully, some multi-dog owners will be by to give more credible than my 1 dog background,
but, i'd think, you may want to teach the small dogs to go to their mat.
Ignore ignore ignore the small dog's attempts to horn in on the action,
BUT, the moment small dog sits down, or looks away, or steps back, REWARD! tossing treat AWAY from where you are working with Hannah.
Dogs are
shockingly keen to observe
precisely WHAT earned them a treat. Lol, as you will soon discover, if you DO mistakenly reward 1 wrong move, lol, the dog WILL notice that, and do the trick wrong for a lil while, you'll see! We've all done that. Not to worry, it can be remedied by ignoring the wrong move a few times, it fades back out then.
so have the small dog (well, actually, i guess "
younger" dog would be more accurate, sorry)
sit somewhere else, or across the room on her mat, and begin lessons with Hannah.
Yes, you are right, small dog WILL run right over at the site of treats,
and maybe,
you can lead small dog back over to her mat. If small dog knows "stay" you could use that cue, too.
Sit down with Hannah, and toss treat over to small dog
on her mat. Take care not set up a "i run over, mom leads me back and throws me a treat" cycle, as best as you can.
Throughout your lesson with Hannah, if small dog is staying on her mat, you can toss treats over to small dog, for doing the right thing.
Then, of course, when Hannah's lesson is over,
then have a lesson with small dog, too,
and i bet, Hannah will try to scooch over there if she has her wheels on!
but, it can be done. Many of the members here, post "how to" videos, and you can see, their other dogs are in the background, just observing, and waiting for their lesson next.
This might take a few lessons, for small dog to get idea,
"I just never ever get any treat when i butt into Hannah's lesson, but i DO get treats for staying on my mat." So don't give up, don't get frustrated, those dogs are wayyyy smarter than you realize,
and they WILL sort it out, oh they will!!! Or, if you have option to set up a baby gate, or move other dogs to other rooms, that works, too.
Here is "Go to your mat" by one of my favorite trainers who specializes mostly in managing behavior problems more than tricks: (not ALL trainers on youtube are positive only) The first half of this video is for you, the rest of it, is a lil more advanced than you need right now, but, still fun to watch. All kikopup videos are usually only about 5 minutes long.
