Claire Laster (she/her/hers) is a dog trainer and behavior consultant with Pet Harmony. Claire’s favorite part of her work is creating communication and understanding between furry friends and their people. She knows that understanding what your animal is trying to tell you is the key to cultivating a more confident pet and more harmonious lifestyle for the both of you.

Claire’s journey started her in the world of theatre. Though she truly loved her experiences there, she felt something was missing, and it turns out that thing was furry critters. She started by working in doggy daycares around the city of Chicago until she was able to begin apprenticing under an experienced dog trainer. She spent as much time as possible learning science based, positive reinforcement centered training and behavior modification.

From there, Claire found the incredibly fascinating and wonderful world of behavior consulting and knew that she wanted to spend more time focused on helping pets and their people learn ways to connect, grow, and problem solve together. She loves helping create a plan to ensure that every member of the family has their needs met!

Claire is a member of the IAABC and is Fear Free Certified, as well as a Certified Professional Dog Trainer-Knowledge Assessed.

Kind Words From Happy Clients

“If you love your pup and your own sanity, work with Claire. She has been an absolutely stellar trainer, teaching both us and the dog simultaneously which has helped us develop an understanding of our pup and our bond with her. Claire’s insights have always been spot on, and her flexibility with scheduling has made the whole experience a breeze. We cannot recommend her nearly enough!”

“I met Claire in July 2023 a couple of months after bringing home my golden retriever puppy, Sherman. As a first time dog owner, I felt overwhelmed and not very confident in raising Sherman to be the loyal and well-mannered dog I dreamed of him being. I signed up for Puppy Manners class, in hopes of socializing Sherman, and learning some basic commands. I was so impressed with Claire’s breadth of knowledge, patience, and willingness to troubleshoot any issue. Dog behavior & learning is very complex, and she was always willing to dig into figuring out exactly what was throwing us off. We graduated puppy manners school and she sent us off into the world to continue to develop our skills! After a few weeks, Sherman was struggling with pulling on the leash & also was choosing to not obey commands I knew he had down already. I gave Claire a call and she talked me through some options. We opted to go with private at home training for 1:1 attention and to see Sherman operate in his home environment. Every single issue I presented Claire with, she was able to solve in 1-3 sessions. I was so pleasantly surprised with how quickly he progressed in this setting. I strongly recommend Claire to train your furry best friend. Beyond training the dog, she can help coach you on how to best handle different issues. I feel so much more confident & Sherman has grown into such a sweet and loyal pet with her help!”
