About Eileen Eileen Gillan is a certified dog trainer and member of the Pet Professional Guild. Her philosophy is simple: dogs are our best friends and we should treat them that way. She would never do anything to a dog that she wouldn’t do to a child. That means no choke chains, no prong collars, no shock collars, no use of pain, fear, intimidation or domination. That doesn’t mean dogs don’t have to learn the household rules. It just means that we teach them what we want in a way they can understand, remembering that English is a second language for dogs.
