Riley: Hell no. Unless your only requirement is a giant freak Malinois
The cons definitely outweigh the pros in his situation. Which is too bad because he is extremely intelligent and powerful when he can be kept under his threshold.
Aura: Still going to say no because she is from the same gene pool as Riley and I also don't have traceable lines to draw from (knpv is all I know). However if it were hypothetically based just on her temperament and health alone, and it was guaranteed that the puppies would be just like her in this magical world, then I'd say yes, because she's pretty awesome.
