A dog trainer teaches dogs how to obey common canine commands and exhibit positive behaviors. In this role, you meet with the dog owner to discuss negative behavioral issues and explain your techniques to reduce or eliminate that behavior. Your job duties include designing lessons, employing positive behavioral methods, and updating the owner or breeder with feedback about the dog’s progress. Dog trainers may work with a dog and their owner or breeder from the time they are a puppy until they grow into adulthood. You may work for a pet training company and offer basic and advanced canine training classes, or you may choose to become an independent contractor and find clients on your own.
