“Before I found Ren my dog was totally out of control.  She ended up going over a lot of things with me that were out of wack in my relationship with my dog.  Now I’m able to show my dog who is the leader which has helped with her anxiety issues tremendously.  I definitely recommend Ren if you are struggling with your dog.” -- Emma W.

“Ren came to help us with our Italian Greyhound /Chihuahua mix who was completely out of control. Before working with Ren, he was wild, stubborn, would not respond to any of our training commands, and chewed up everything in the house he could get his hands onto. After working with Ren for just a few days, he became an angel. We actually started to enjoy his presence and personality.

Highly recommend for any difficult dogs!” -- Kevin M.

“I have a Jack Russell mix who after training with Ren is within the speed limit. Ren has been incredibly patient with training my pup and with me, who needs the most training. Ren has been totally responsive to e-mail questions and and a blessing in our lives. My dog’s behavior had become a deal breaker, and Ren has trained me and my dog how to have a life together. After a few sessions, I have a totally different dog, and a totally different way of working with her. Thank you Ren!” -- Jonna A.

“Ren tells it like it is while giving owners the guidance they need to transform their relationships with their dogs. She is one of the most hard-working & dedicated people I know; she’s constantly learning, growing, & improving her skills. And she’s a fantastic human being in addition to being an awesome trainer!” -- Melissa M.

“Prior to our experience at Balanced Pack K9 training, we were at our wits end with a screaming and bossy jack Russell puppy and an anxious and high energy Boston Terrier. We tried multiple puppy classes and visits with in home trainers. Nothing worked. The in home trainer recommended we re-home our 7 month old puppy as she was completely unmanageable. Behaviors included fighting with our 12 year old senior dog, screaming in her kennel, barking from the back of the couch and chasing the cat. We knew that something had to change and that purely positive training wasn’t working.

We left our two wild girls with Ren at Balanced Pack K9 Training for a weekend board and train and it’s radically changed our life for the better. You can see Dolly and Ruby’s transformation on Balanced Pack K9  Training YouTube, Facebook and Instagram pages. What you don’t see is how Ren also transformed our approach to the dogs with thoughtful coaching. We are continuing her training at home. It’s been two weeks since their board and train and the crazy loud house is a thing if memory. What has surprised us the most is that the dogs are more relaxed having boundaries and a job, even if that job is just holding place or heeling during a walk. We wish we had found Ren sooner. If you are hesitant and e collar training, you don’t have to be. It works but really should be under the supervision of an experienced trainer such as Ren.” -- Kara B.

“Ren Marshall trained my dog Turbo. When we got Turbo he was a mess. We rescued him from a home where he had no structure. He was not housebroken and suffered from anxiety and leash reactivity. He was scared of people and other dogs. Over several months Ren regularly worked with Turbo using the prong collar and e-collar along with the place command and structured walks. Turbo is now a joy to have around people and other dogs. He is way less anxious and is housebroken!  Thanks Ren!” -- Olivia P.
