Support your dog trainer by sharing your story

Hi! My name is Cassie and I've been training the animals of Denver since 2016. I have my bachelors degree in Zoology and Animal Behavior. I began my career at the Downtown Aquarium determined to take care of marine life. I began as a volunteer and was working my way up the ladder when I got a job offer from the Denver Zoo. Being fresh and eager to advance my career I took the job and became a trainer. However while I was there something just felt off. I spent the next couple years getting trained at animal clinics and working various jobs trying to find the right path. A friend of mine then reached out about training questions for her new puppy and everything began to click. I left the exotic animal world behind, picked up my clicker and training treats and stepped into my new role as a dog trainer and I haven't looked back!

Certifications:

B.S. Animal Behavior and Zoology

Dog training services include

  • In home training
  • Reactive dog training
  • Puppy dog training
  • Off leash dog training

More info about Cassie Sorensen's dog training:

I provide one on one in home training to help you and your dogs reach their goals! I teach basic manners courses for puppies and adult dogs, reactivity, day training, and trail training!

Behavioral issue focus:

I often work with dogs who are dealing with reactivity - on leash, in the house, in the car, etc. I work one on one with you and your dog to build a training plan that will assist them moving through this behavior challenge in the best way to help them live a calmer, more comfortable life.

Dog training methods:

I base all of my training on a positive reinforcement reinforcement model with the least intrusive ways to train. I always begin with a consultation to see what your goals are for your dog and what you are currently dealing with. This time helps me to get to know you and make sure I am the best fit for your needs. From there I create a training plan around those needs based off single sessions on a weekly basis.

Why I became a dog trainer:

I believe that owning a pet is an amazing and rewarding experience, but also a responsibility, not a luxury. Training your pets properly will lead you to a greater understanding of your dog and build a life long trusting relationship and it’s a reason why I became a dog trainer in the first place. I firmly believe in the owner-pet relationship being one of mutual understanding and respect! My goal as a trainer is to help my clients find the best way of communicating with their pets to further that relationship.

My favorite part of being a dog trainer:

So many things! I love meeting new dogs and people, I adore working with puppies, and I love the day to day activities of training. The thing I love the most though is when I am working one on one with clients and get to see how excited they are when they are noticing progress and finally feeling like they are able to communicate with their pets. It’s such a great feeling bridging that gap.

My #1 dog training tip:

Don’t ignore reinforcement. It can be hard to separate what treats are in our mind from what they are to dogs. And I know it can feel like you are giving your dog this endless supply of extra food each day but they are such a great tool in teaching our dogs what they are doing correctly as well as have the ability to change the emotional response around certain situations.
