Tim Howard
Owner / Trainer
Tim Howard From the stage to the training field, Tim Howard has always had a passion for connecting with both people and animals. With a background in entertainment and magic, Tim’s life has been filled with creativity, energy, and a unique ability to build trust and bring out the best in others. Over the years, dogs have been a constant part of his journey—even playing roles in his magic shows. That bond with animals deepened when Tim rescued Ruby, a mixed breed who was scheduled to be euthanized. Giving her a second chance at life became a turning point. In changing Ruby’s future, Tim discovered that she changed his as well. That experience ignited a calling: to dedicate himself to helping dogs and their families thrive together. Now, through Four Corners Dog Training, Tim works his magic on dogs—not with tricks or illusions, but with patience, positive reinforcement, and an understanding heart. His mission is to create lasting bonds between people and their pets, transforming lives one wagging tail at a time.
