It never hurts to have more research in favour of using positive reinforcement methods in dog training rather than force-based training. A new study on companion dogs, led by biologist Ana Catarina Vieira de Castro of the Universidade do Porto in Portugal, showed that dogs trained with positive reinforcement showed less stress, and learned faster (yay!) than the dogs trained with leash jerks and loud aversive voices. No surprise here at all, but always great to have more good data in our pockets.
