Dog Training in Thornton, CO

Dog training in Thornton is essential for helping dogs develop confidence, impulse control, and reliable manners in a community filled with busy neighborhoods, open spaces, and family-friendly parks.

As Thornton continues to grow, dogs are exposed to a wider range of daily distractions—joggers, bicycles, other dogs, and active playgrounds—which can challenge even well-mannered pets.

Owners often seek training when their dogs show signs of pulling on leash, jumping, reactivity, or difficulty settling around everyday activity.

With consistent guidance and structured practice, dogs learn how to behave calmly and predictably, making outings, neighborhood walks, and at-home routines far more enjoyable for the whole family.

Amazing! Our dog had reactivity issues with people running, people on bikes, delivery tucks and motorcycles. Logan and Ashley helped us learn the body cues of our pup to get ahead of any issues and now she can sit and watch the world in peace. Highly recommend!!

Logan and Ashley are exceptional trainers. I have a very stubborn Chow Chow who tends to do things on his own terms, and I was struggling significantly before reaching out to them. After a few consultations and training sessions, I saw noticeable improvements—not only in my dog’s behavior, but also in my own handling and understanding as an owner.

We couldn’t recommend Sit Happens Dog Training more! We are on our six out of seven training sessions, and our once very reactive bully rescue, has improved SO much! Before training she would bolt if she was off leash. Today we got to the point where we dropped the lease and recalled her back to us. It was heart warming to see her happy little self run back to us. We are so grateful for Logan, Ashley and Sit Happens as a whole!

My family and I can not express the pleasure it was having Sit Happens come to us and work with our 4 legged family member.

Logan and Ashley both were fantastic. Logan was a wealth of knowledge when it came to how to interact and work our puppers! Logan made sure to always be available and was able to explain and demonstrate the different tasks.

The knowledge our family received from using Sit Happens is so beneficial and help relieve any stress when introducing a new pup to the family! I would highly recommend Sit Happens and their wonderful trainers to assist with what ever needs your four legged family member needs!

Thank you Sit Happens!

We couldn't be happier with our experience using Sit Happens!! Upon adopting our doodle mix, we knew we wanted to work with a trainer to make sure everyone in our home was set up for success. From day one, Logan provided guidance that made training approachable, effective, and genuinely enjoyable for both our dog and our family.

Logan and Ashley are both incredibly knowledgeable, friendly, and genuinely passionate about what they do, which made the entire training experience fun and motivating.

I would 100% recommend Sit Happens to anyone looking to add a furry, four‑legged member to the family. Do the homework, ask all the questions, and I promise you won’t be disappointed! The success we’ve had has been truly invaluable.

Although we have had dogs in the past, we decided to hire Logan and his team with our new puppy, Mac, a rough collie.

With our Mackie we had some challenges that we had never seen before with a puppy: fearful of stairs and weary of surfaces. Logan and his coworker, Ashley, helped us and our new puppy. Logan even gave us valuable tips for leash walking, giving commands, and introducing new ones.

We are so grateful for their overall support and knowledge. We would highly recommend Logan and his team. You certainly won’t be disappointed!

Both Logan and Ashley have been super helping training my younger dog Gabe to not bark and get used to hearing noises and being calm at his spot. They have been so wonderful and helpful and if we have hiccups in training I love that I can reach out to them directly with any questions or concerns I may have through the training. Highly recommend yes it's expensive but worth it!

We are extremely happy with the results of our training with Logan. Relaxed, no pressure, progressive training program. And it works! We have a beautiful black Miniature Schnauzer. He is our 4th Schnauzer so we know this wonderful breed well. Loving. Loyal. Protective. Fun. Full of life. But stubborn and willful. We have had to warn our visiting friends about the “SchnauzerWelcome”. Very boisterous. But now with Logan’s gentle guidance we no longer dread the chaos of arrival of friends. And walks are no longer a tug of war. He is calmer and even more affectionate. We highly recommend this company. Great name and highly effective program. We saw a dramatic difference in just two lessons.

Frequently asked questions

Do you help puppies and dogs of all ages and breeds?

You bet! Sit Happens is the most established dog training provider in the Denver area with over 14 years in business and 10,000+ dogs trained. We’re experienced in working with puppies and dogs of all life stages and have catered to more than 250 breeds.

What makes Sit Happens different from other dog training services?

Sit Happens is the leading dog training provider in the Denver area, and we also proudly serve Tampa and St. Augustine. But we’re more than just another dog trainer— we’ve earned our reputation for a reason. While typical training might focus on getting your dog to follow commands, we go beyond the basics. Our approach is all about your dog’s overall wellbeing, helping them feel comfortable in their environment and strengthening their bond with you.

We make sure you and your family are part of the process, giving you hands-on lessons and exercises to practice with your dog between sessions. This way, you’re not just teaching your dog commands— you’re building an unbreakable bond with your furry friend.

Are your trainers certified?

Yes. Each of our trainers goes through a rigorous 90-day certification course. We only hire trainers with extensive prior experience who pass our thorough vetting process. Each of our trainers also carries their own professional accreditations and affiliations. They are required to undergo 100+ hours of continued education each year to stay up-to-date on the latest science-backed methods.

Can you make sessions fit my schedule?

Of course. One major advantage of private training is that it fits into your lifestyle. Other training services make you drive to a facility on a strict schedule and charge extra for the flexibility of in-home lessons. At Sit Happens, all of our training plans are designed to work within your schedule.

Can you work with multiple dogs?

Yes, we can either train each of your dogs individually or hold private group sessions with all of your dogs together. Each of our trainers can work with up to five dogs at a time.

Does my dog need to be up-to-date on their shots?

Yes. In order to keep you, your dog, and your trainer safe, we kindly ask that you ensure that your dog has received all their vaccinations.

Is private dog training affordable?

Yes, the cost of private dog training is comparable to group dog training, yet it’s twice as effective. In a group training setting, your dog has to overcome the distraction of other dogs they don’t know while still trying to learn the basics. Private training offers an array of additional benefits, including flexible scheduling, personalized lessons, and one-on-one attention from the trainer.
