Hehe, yes! Milly has learnt a couple of things without me teaching her.
"Bring it back!"was my unintentional "fetch" command.
Also, every morning she does a huge stretch, and I always subconsciously commented to her "big stretch!", so now she stretches on command
it's hilarious.
"Let's go!" When she's on my lap and I want to stand up, and she will spring up.
Finally "what have I got for you?" when I'm about to produce a new toy or treat I just bought. She will always come running for that now, without fail.
