Dion R. Studinski    

Professional Dog Trainer, Owner & Founder of Ancillary K9 Dog Training

Voted one of Denver’s top dog trainers year after year, Dion Studinski at Ancillary K9 has had dogs in his life since childhood. With his diverse background and experience, he is confident he can make a difference in your dog’s behavior and in the quality of your life.

After years of experience as a trainer, Studinski has heard new clients describe their dog’s behavior in similar ways more than once. Those feelings, he likes to explain, are normal. Without training, most dogs are naturally hyperactive. This can present itself in a variety of ways. At its best, your dog may be hard to walk on a leash or impossible to take to the park. At its worst, they can become destructive and even aggressive.

Still, Dion believes there are no “problem dogs,” just ones who haven’t been properly trained. By combining his lifelong love of dogs with the mentorship he’s received from some of the top dog trainers in the U.S., Dion is committed to improving the lives of the people – and animals – he works with.

Understanding and Mitigating Aggression in Dogs

It’s not uncommon for dog owners to experience behavioral issues with their dogs. Most family dogs behave in friendly, playful ways when they’re at home and around familiar members of the household, but may display signs of canine aggression against both humans and other dogs in certain situations outside their home environment. Sometimes a dog can show signs of aggression towards other dogs in its own family as well, such as with resource guarding and other behavior problems.

Aggressive behavior in dogs can become a real problem if left unaddressed. If your dog acts up around strangers or even around family members, a private aggressive dog training program led by a professional dog trainer can help your canine companion learn to act appropriately in these stressful situations.

If your dog is quick to bark, growl, snap, or even bite, your four-legged friend may have a serious behavioral problem. Aggressive dog training is one of the most important reasons a dog owner will seek the assistance of a professional dog trainer. A dog owner should be very concerned with aggression in a large dog, working breed, or “bully breed”; however, small dogs are a concern too.
