Our dog was very reactive to noises, people, and other dogs while on walks. After Randy worked with us he is now calm, walks right by our side, and doesn’t react to things around him anymore. We’re so grateful for Randy and the difference that he made in Henry’s behavior.

Randall was great to work with! I really appreciate the in depth explanations of everything during training sessions. Very informative and encouraging while leash training. Definitely recommend

I could not be more thrilled with the results I was able to attain with Diamond Dog Academy and their balanced approach training method. I got my bernadoodle puppy at 8 weeks old and struggled for 3 weeks with potty training, crate training and general handling until we met with Randall for an evaluation. I began with the Early Puppy Development program and all my initial struggles disappeared! After Alfred turned 16 weeks old we began the On-leash training program and by session 6, I found myself in control of the most obedient and well behaved puppy among any of my friends or family members! I could not be more thankful for what I learned. I highly recommend hiring Diamond Dog Academy!

I started working with Randy and my Golden Retriever, Enzo at 14 weeks old in his early puppy development program. Since then we have completed both the on leash and off leash training programs and are now working towards attaining my Service Dog Certification. I am an above knee amputee and can not speak highly enough of the training program Diamond Dog Academy provides. If you do what Randy says and stick with the program, you will have an amazingly trained dog. I started traveling on planes with Enzo at 4 months of age, and he was perfect in the airport and on the plane at that age. He has been on 8 trips so far in his life and he is 1 years old. I take him everywhere with me and never worry about how he is going to behave. His attention in the airport was on me and my wife the entire time and was not distracted by other travelers trying to get his attention because he was a cute puppy. Right now we are working on soft mouth retrieval, so that enzo will be able to bring me my shoes, keys and crutches on command. I cant wait to get Enzo to his Service Animal Certification. It will make my life alot easier, and Enzo loves the challenge! Do you and your pup a favor and work with Diamond Dog Academy!
Randall worked our one year old German and has not only drastically improved her general obedience but her dog reactivity as well. He’s super responsive and will train at any location. We even went to a brewery once to work on her around other dogs in tight spaces!
