We have sent both of our dogs to learn with Kati. She is very knowledgeable and we are forever thankful for the tools she has given us to live a more peaceful life with our pups!!

Wow! Our 12 week old Vizsla went to puppy board & train with some typical bad behaviors like jumping, mouthing, and pulling on the leash. 10 days with Kati and he was showing us everything he learned! We were super impressed how focused he was working with Joyce while we were standing nearby. Step by step they walked us through each of the commands and how to use the training techniques for positive reinforcement and correction. He was so eager to do the training sessions and was really enjoying the work with Kati. Thanks to our friends that recommended her and a super big thank you to Kati & Joyce!

Jack, our 2 year old, 70# shepherd mix had several issues we needed to address. He pulled like a mule while on walks. He also often had issues with other dogs and people during these walks. When we had guests over, he jumped on them and then had trouble containing his excitement. Basic commands like sit, stay and come were often ignored. Taking him to an outdoor restaurant or pet store, with lots of people and distractions around, were unpleasant experiences at best. We tried group training and also a few personalized training lessons with little success. My wife learned about Diamond K9 Dog Training and we decided to do the 2 week board and train program. Initially, I was hesitant about e-collar training and having someone else train our dog. After speaking with Kati, and doing more research on e-collars, those concerns went away. After getting Jack back and seeing the results, we could not be happier. When we picked him up, Kati spent a few hours explaining how and when to use the e-collar, commands, and everything else we needed to keep Jack on track. We’re able to walk him with little to no pulling and he’s able to stay in the heel position even with distractions like runners, dogs and even a flock of turkeys. He’s able to stay in place when someone visits our house and even when released from his place, he no longer jumps and is able to contain his excitement. Seeing how much Jack changed in just 2 weeks was amazing. We could not recommend Kati’s training enough.
We cannot say enough good things about Kati (and Joyce). We sent one of our dogs for a 30 day board and train to work on his anxious/ nervous behavior. We also did 4 private sessions with our 2nd dog to help to manage her prey drive and some unwanted behaviors. We have seen a massive improvement, and have learned so much ourselves in the process. We would not work with anyone else moving forward!
We brought our Bernese mountain puppy to Kati for the board and train and it was the best investment we made! She came back knowing many core commands, listening and behaving much better and we had the tools we needed to continue to make progress. Kati is always extremely responsive and gave us a ton of helpful advice even well before and well after the board and train. Would highly recommend.
