"If you are on the fence about sending your dog for training at Maximum K9, this is your sign to DO IT! My husband and I were hesitant really just because of finances but I’m telling you it’s worth every penny! We spent hundreds of dollars on trainers coming to the home and nothing really helped. We finally decided to commit to Maximum K9 after months of putting it off. I’ll just say, I wish we did it sooner!!! I’m not sure if they allow you to pick your trainer, but if they do, KATIE 100%!! She is so knowledgeable and really shows that she cares for your pup. It was amazing to see the relationship our dog Nico and Katie had when we came in for the demos. Of course I was sad, but I felt comfortable leaving Nico each time because I knew he was in great hands! My husband and I are very excited to continue working with Katie and Maximum K9 to keep Nico on track and build his foundation!!"

"I brought my 2 and a half year old standard poodle May here for the 6 week behavior modification because she wouldn’t do well on walks when we saw most people and she would lunge and bark at other dogs. After maybe 2 lessons with Nicole I was able to take May on walks without worrying about her behavior towards other dogs. It was like night and day. They give you and your dog the proper tools to set them up for success. I have recommended Maximum K9 to so many people who have dogs because this place really is great. Everyone there is so kind and they genuinely want to help your dog. May isn’t even finished with her 6 week program but I am already looking into putting her in one of their sport programs because she has done so well these last 4 weeks and she loves going to training. I am so grateful for finding this place!! So worth it."

Excellent training facility. Our Rottie was a rescue at six months with no training and several bites. Maximum K-9 evaluated him and provided advice, training, and ongoing support. Essentially saved his life as we were his sixth home in as many months. Three years later, we have a great dog and a continuing relationship with Maximum K-9, Joe, and his staff. In addition, we have gotten equipment from Max K-9 including a Dog Runner treadmill. Max K-9 and staff are terrific! Highly recommended.

Brian Burke

I highly recommend maximum k9 they are very attentive and thorough. Their trainers are extremely knowledgeable and their techniques work! I can 100% confidently recommend Maximum K9 if you're considering any form of training for your dog.

Maximum K9 is the premium one-stop shop! I have been buying raw food from them for 10 years now. I was skeptical at first since my dog is small, however, she has been doing great since changing her over. Her coat is always healthy and she never had a medical issue. I can’t thank the staff over at Maximum enough, they are all “1st of class” - Thanks Maximum K-9

"Thank you Morgan and the rest of the staff at Maximum K9. Even before my dog's board and train - Joe was able to help with a barking issue. But seriously I think you guys switched my dog out LOL! Winter is a rescue, she was dog reactive, horrible on her leash and now she has completely changed for the better. Morgan was patient and informative. You can tell the staff really get along and have a great energy. Thank you guys so much."

"My German Shepherd, Zeke, was especially reactive to other dogs and would drag me while walking, which made me incredibly stressed about taking him out in public. I had debated a long time about doing the board and train due to the cost. However, it is without a doubt worth every penny. He had amazing trainers, Nicole and Katie, and I was so appreciative about how kind and communicative they were during the entire process. I honestly cannot believe what a difference in behavior Zeke had after two weeks. They went above and beyond my expectations, and I am forever grateful. You will not regret using Maximum K9."


I can't find enough good things to say about Maximum k9. Top-notch training services... group or private, they do amazing board and train, have their own line of raw food, a great store for supplies, and finally, the owner breeds the most amazing Rottie line and as a Rottie owner for life the only breeder I trust. I'm a successful business owner as well as a dog person. Maximum k9 clicks all my top-notch buttons as the best for dogs, food, supplies, service, and training. Just go and see for yourself. They won't ever disappoint.

Just completed a two-week obedience  Board and Train for Lincoln and couldn’t be happier. We now have a great foundation to build on. He’s taking verbal and nonverbal commands and following through. Katie was absolutely amazing. We are going to continue some private training with her and will be taking advantage of the lifetime classes. Maximum K9 is WONDERFUL.
