A Professional Dog Trainer never stops their education. The science of animal behavior continues to explode with new findings. Keeping updated is important in the sciences. The science, peer reviewed studies, support that dogs learn best when compulsion is not used. Reward Based methods build the human/animal bond.
All dogs learn the same....reinforcing behavior with something that is highly rewarding to them.
Both my dogs are adoptees. Lexi is 8 years old and Grace is 18 months. They both have taught me a lot and continue to. Very different in personalities. Grace has resource guarding issues which we continue to work on and improving. Lexi has competed in Rallly, plays agility, CGC and therapy dog.
