Tarzan was our first Leonberger. Our oldest leaned walking while holding its fur, learned swimming while lying on his back. When we worked on our house, Tarzan was guarding her... Trained water rescue dog
I think it will take some more decades till I trust into a robot dog to do the same for my then grandgrandchilds.
In my opinion robot animals (which I know) are for the age group between mid-teen till family with yet no kids.
We have two ecosphere and 3 baiosphere for having animals and plants with no need to care for them, Closed systems, selfsupporting.
