My eighty year old parents looked after my brothers Cavalier King Charles Spaniel for a few days, and my Mum almost put herself in hospital trying to wear him out. He's clearly got a copper coloured top, because you can't wear him out, he'll just keep on going and going. My parents didn't realise that at the time, which was probably a mistake on my brothers part to not tell them this!
To be fair, whilst my Mum was brought up with a dog, and has had a few dogs, that was all many years ago, and for almost all of the later years of her life she'd only had cats, so maybe she'd got out of practice, or had forgotten that she wasn't still in her thirties, as she was the previous time she'd had a dog!
It sounds like Google is a bit of an exception amongst Cockapoos, although the Wikipedia article on them does suggest that their traits are quite variable, so I guess given that they are a relatively recent breed (and not really recognised as such by any organisations), there's going to be a lot of variety to what is called a Cockapoo, and what sort of behavioural characteristics it'll have.
