Hi,
Actually that's almost the exact opposite of what they found during the experiments on the silver fox in a 50 year experiment in russia.

Intrestingly it also brought with it unexpected physical changes that we see in dogs such as shorter legs, differing coat patterns etc.
Quite a facinating study overall.
