You know what they say: if you can't buy it, breed it. Well, we're kind of a step ahead of that. Because at Shield K9 - Dog Training Toronto, we specialize in training all breeds and temperaments of dogs, so if you have a highly-aggressive dog or puppy (or just a stubborn one), we can help! Our dog trainer in Toronto has over years of experience and a proven track record with all breeds of dogs—so you can trust us to get the job done right. We first started working dogs over years ago as K9 handlers for a private security company. Since that time, we've spent years studying canine behavior, learning theory, and psychology and now we're ready to apply what we've learned to help you. Our experience includes behavior modification and aggression rehab; protection training; competitive obedience...the list goes on! We now have our breeding program producing some of the best working dogs in the country.
