Testimonials
Carol from Canine Harmony is the best thing that happened to our dog! We are first-time puppy owners who had absolutely no idea what we were doing! A friend recommended me to Carol, and she was a lifesaver! Very responsive, obviously caring about animals and their owners, and brought so much joy to our household when she came to train! She taught us what to do, answered all of my worrying text messages all the time (without charge), and thoroughly trained our dog and trained us how to train! My youngest still asks when Carol is coming over. Canine Harmony is highly recommended! You will not regret it!

I have alway used professional trainers to work with me and my new puppies. This past October, we purchased a Goldendoodle pup. I had called several trainers prior to receiving our puppy. When Carol returned my call, I knew she was the right choice. She was friendly, caring, and very interested in what I had to say, and listened to concerns I had about getting a new puppy. So we planned a start date a few days after Mia arrived. The day after I got Mia, another dog came onto our property and attacked our puppy aggressively while I was walking her on a leash. Mia, thank goodness, was ok physically, but after this incident, she would not leave our porch and howled every time she smelled another dog on the block. Carol came and started her magic. She introduced Mia to “safe” dogs and her patience was amazing. The first time Mia saw another dog on our property, Mia panicked, screaming and cowering on the porch. Carol just encouraged Mia patiently, step by step using positive reinforcement and kindness. After a while, Mia was lying next to the other dog and wanting to play. She encouraged Mia and me all the way. I was so happy, I started to cry! Now, Mia loves to play, and she is socialized beautifully, loving her fellow canines! Carol encouraged us each week, with all our training challenges and Mia is doing great! Mia graduated basic obedience, and we look forward to learning more from Carol in obedience training. I will recommend to everyone.
Thanks Carol for all you did.

Our rescue dog Haku is the sweetest dog but he is on the shy side and in need of a confidence boost. Carol was recommended to us for her positive reinforcement training and her caring and gentle approach with dogs. From the second we met Carol, we knew it was going to be a great match. Carol is extremely knowledgeable and taught us a lot, always in a fun and caring way. Thanks to Carol, Haku’s confidence is shining through and he has made tremendous progress in obedience training. Carol went above and beyond to expose Haku to various situations each and every week to build his confidence and we are so happy we found her. She is very flexible in her training approach and will tweak her ways to use what works for you and your dog. She demonstrates and explains the different exercises really well to help us achieve the best results fast. She is a very positive, friendly and upbeat person and it’s always a pleasure to attend the lessons, both for us humans and for our dog! We would highly recommend Carol / Canine Harmony.
