NK-9 usage

"We strongly believe that NK-9 has given Jack (14 yr old beagle on NK-9 for 2 years) added years, and we are so grateful to have him spend that time with us. He shows no sign of declining health, and in fact he seems healthier all the time."

Jan O., Florida

"We have two old mixed breed dogs and we have been so pleased with the increased energy in them after using NK9 and DGP. There have been no side effects and we are so happy to have our pets doing so well."

Cici V., Virginia

"Hospital work is grueling for our working dogs. We provide Animal Assisted Therapy Programs, Service Dogs, and Dog Training in the Atlanta area. It takes highly trained, healthy dogs to provide patients with the best service. We rely on NK-9 and DGP to keep our dogs healthy and sound."

Kellie C. at Cosby's Therapy Animals, Georgia

"I have an 11.5 year old black lab German Sheppard mix who weighs 115 pounds. He has experienced problems with seasonal allergies for the last seven years. Our normal summer time routine has been rounds of antibiotics, antidepressants and steroids to control his itching, chewing and related skin infections. None of these treatments has been more than 75% successful and it usually is just a waiting game for the first freeze to help with his allergies. We’ve gone the route of changing his diet, eliminating foods, ripping out all of the carpeting in our house (replaced with hardwood floors) and have tried various over the counter meds with little to no help.

A nutritionist suggested I try DGP and NK-9. Within four hours of putting him on these two supplements, I could already see a difference in how he felt. His skin looked less angry, he stopped licking and chewing his feet and in general he seemed to feel better. His energy level has increased, he’s climbing stairs again; getting up on the furniture, barking at his one year old brother and for the first time in months he picked up his Frisbee, wanting to play again. He has only been on the meds for less than two weeks. But the changes are very obvious already. I can not wait to see how he feels in a few weeks or months.

These products are truly the fountain of youth for my dog. What a huge blessing for us. Thank you for your help with these products."
