I have a few suggestions as I have had a couple cases of pano in my lines. 1) MSM-- you can buy this at feed stores in granular form. Start by giving 1000mg per day and once you are sure he's tolerating it, double the dose. It will help w/ the inflammation and w/ immune system. Works wonders for me personally w/ my spring allergies and I sincerely believe it's what brought my SLE / lupus into remission years ago. 2) Take a look at what you are feeding. You don't want a food that is encouraging fast growth. I personally have the best luck w/ Eukanuba Lg Breed Puppy as it's scaled way down in calcium, and the protein/ fat/ calories are all moderate. Some foods (even some LBP formulas) are far too "hot" for growing puppies. 3) Fish oil can help acc'g to one of my vets who happens to own one of my fast growing pups who had a mild case of Pano just a month or so ago! And agree w/ Shelley, rejoice in the dx that it's Pano!!! Good luck. Anne
