Momma Risa
No matter whose pups, Risa always feels the need to be grandma and that's rather nice.
She likes the strong ones with their own mind. She no longer has patience for those that just don't get on with it but she does try to 'get' that attitude.
You can see the brain working - how will I motivate this one to get the guts to do the stairs, to achieve x.
I guess once a mom, always a mom. :-)
