"Derby has been a competitive agility dog all of his life placing in numerous classes at National Agility Championships. Earlier this year it was evident that he was showing signs of age catching up with him and it looked like his retirement from competition was near. After placing him on Prescription Diet® Canine j/d®, I have seen no signs of stiffness, even after training sessions and 4-day trials. He is running as well as he ever has and we are working towards qualifying for this year’s Agility National Championships again. "

"I put my 14-year-old dog Sara, a Queensland Healer Mix, that has been showing signs of arthritis on Prescription Diet® Canine j/d®. Sara is now running around and acting much better. She comes to the clinic with me every day and the clients are even mentioning how much better she is.

I had noticed that Sara was slowing down and was not as active, but because she was getting up in age I thought it was age related. Realizing now how much pain Sara must have been in, I am so happy I have Canine j/d® to give to her. I have never been so excited about a product. I am now recommending Canine j/d® for all dogs with arthritis."

"The addition of Prescription Diet® Canine j/d® into Houston's care regimen has made dramatic improvements in his life. He is like a new dog! He is feeling better than ever. He's more playful and is no longer limping. Houston is clearly feeling better since we changed his food to Canine j/d ®. He's rising and walking more easily, and he is more playful. I really think this food is improving his quality of life.

We will continue to feed Canine j/d® to Houston for the long term!"

"It has been 4 weeks since starting my own 10-year-old German Shepherd on Canine j/d® and the change (honestly) has been great! She is off all supplements and anti-inflammatory medications, is chasing squirrels again, playing with the neighbors dog (jumping, playbowing) and overall seems far brighter and less pre-occupied.

My wife Susan and I(both vets) are very pleasantly surprised at this response; for this reason we are recommending Hill's Prescription Diet Canine j/d® "

"I've noticed a lot of positive changes in Lucis since changing his food to Canine j/d®. He's walking and running better and has even dropped a few pounds. Now we can't even keep up with him on walks. He has so much more energy; it's amazing."

Laura and Lucis, (11-year-old Large Breed Mix) — Delaware, OH

"My dog Odie was having problems getting up stairs and on the couch. I have only given him Canine j/d® for about a month. He has been running up stairs and jumping on the couch. I am very happy with the Canine j/d® and I think my dog is too."

"Star Frost, our white German Shepard, is on Canine j/d® to help her improve her mobility. It will be two weeks this Thursday that she has been taking the food.

I have seen a marked improvement in her energy level and in the way she carries her back hip, which was the one that was causing her problems. Before she would have to hop up the stairs and she's no longer doing this but actually engaging in play and wrestling. Overall she just seems to be in a much better spirit and much more mobile. And again, this has only been two weeks. No problems with stool, no problems with any skin reaction."
