I got a new dog named Karo

At last, I now got a new dog. Unlike last time I did not get a St Bernard but a working brder collie.
He is named Karo, and his parents are herding sheep in Norway.

I am going to train Karo to become a search and rescue dog.
He is a social dog, and Karo is a high drive dog that is very kind.
I did not get a St Bernard, because it is impossible to get a working St Bernard as most St Bernard breeder breeds show dogs not orginal St Bernards.
The St Bernard dog is too heavy and has a too low drive to be used as a search and rescue dog.
