Founder – Head Trainer – Head Breeder
Our clients love us!

After testing multiple dog trainers in the Vegas area and weighing up the options, Melissa stood out head and shoulders above the rest. Her demeanor, in-depth knowledge and passion for dogs is really second to none. Melissa helped us not only to train our pup, but also how to understand his behavior. I would 100% recommend her services to anyone looking for a dog trainer and could not be happier with the results!

Melissa is wonderful. She is very understanding and listens to all of your concerns about your pet. She knows how to handle your pet with love but also shows discipline. I would recommend her to anyone!!!

Very good place to purchase a good German Shepherd. The owner has a great understanding of the breed and takes very good care of the puppies and parents. She will even set up training if you wish. Can't say enough good things about the kennel or the owner. We bought our two dogs from her and couldn't be happier.

n June of this year I purchased a puppy from Von Weiss Kennels after several long conversations with Melissa via phone. This not so little guy is paws down THE BEST PUPPY we have ever had. She does everything possible to raise her litters the right way. Trooper has a great personality, extremely stable temperament, super solid environmentals, and as such can be taken literally anywhere with no issue at all. On top of being a joy to live with, he is exquisitely trainable. 10/10 will be coming back to Melissa when it's time for a new addition to the family.

I don't know what I would do without Melissa's help and guidance. I have a West Highland Terrier who came from a questionable breeder. She suffers from several behavioral issues including aggression and separation anxieties which Melissa is addressing head-on. Stella took to Melissa immediately and feels relaxed with her during the training sessions. Not only is there a professional relationship formed but a personal one as well which makes the training experience successful for all. I would not hesitate to recommend Melissa and her service to anyone. I am truly thankful for all she has done and continues to do for me and Stella.
