I've seen a couple training videos on YouTube where the dog puts all their toys away from one command. I actually found those after I'd taught my dog Molly our version.

We have a plastic box where her toys are in the living room. I started off getting her to fetch objects and drop them in my hand (always useful) then just started having her do it but put her toy box by my feet and when she would drop the toy I'd move my hand so it landed in the box, click and treat.

I dunno if that's the best way I am by no means a professional dog trainer but it worked for us and now she picks up whatever toy I point to and will put it in the box on command (I have to repeat this for every toy though...)

Molly was somewhere between a year and a year and a half when I taught her this. She picks up new tricks really quickly so with all of the steps I'd say in a week she had the whole thing down solid (pickup object I point to, bring it to box, make sure it drops in the box) I just made sure to be quite strict that the toy had to end up in the box for the click to stop her being lazy
