We brought our guy home when our girl was 11 yo. typical puppy nuisance antics. When our guy was about 5 mo old Dh decided one night to set up a treat search area in the livingroom,where he placed bits of treats in multiple areas and brought our old gal and our pup in to see what they would do. Our old gal caught the treat scent quickly and started hunting, our pup followed our old girl for a while then realized what the game was about. It became a favorite game that they did together, our gal hunting in one direction towards a scent (treat) and our pup in the other towards another scent.
Dh did this a lot and from there, I started including both pup and old girl in fun training sessions giving the name as the first que to who I wanted to do a specific command first. It didn't take very much effort to get both to understand this new game of taking turns. It was a really good way to keep the pup out of the old girls fur, really good mental stimulation for both and a great exercise for the pup in self discipline. Our old girl passed on 4 yrs later but boy this brings a smile to those memories. One caveat, I only did this in the house, the yard would have had too many distractions for the pup at that time.
If you try this, just be patient, keep a sense of humor and keep at it. Both will learn a lot by watching and by doing. Oh, also both dogs need to already know and be able to do the basic commands that have been taught separately. Once they learn the game of your turn/my turn really well with known commands, start teaching new commands together using your turn then my turn or change the game to suite your own likes and needs.
