Who is PAX?

PAX was a real German Shepherd and he is featured in our logo (tongue out an all). PAX’s journey included a traumatic physical and emotional experience that left him with people saying he was no good. When Marcus McCullough, a PAX Board Member and founder of Limitless K9, found PAX, he was with a greedy breeder and he was like a wild tiger. After getting the proper training and lots of love, PAX turned out to be one of the best service dogs we have ever seen. His story will forever be used to warn people about bad breeders, and the importance of having the right love and training for emotional support and service dogs.

Who Trains the Dogs?

Our dogs are trained by Limitless K9. Limitless K9 has been providing elite home-trained service and protection dogs to families across the USA for years. Their protection and service dogs are bred and raised to be independent critical thinkers and loving working members of their families. The PAX’s K9 Cure dogs will be trained with the same level of care and attention they give to the elite service and protection dogs.

While it means a lot to us to warn people about bad breeders, it is most important to us that we provide highly trained dogs that have received the right kind of loving and care to every victim.

Marcus McCullough
