We have been using the Pet Health+™ formula for our chocolate lab, Shasta. She has had a chronic lameness in her front leg for almost a year. We tried everything. We put her on various supplements, medications, changed her diet and exercise routines and have had countless vet visits, and have even gotten xrays. Nothing was working. Now, after just 3 weeks on Pet Health+™, there has been a marked difference in her gait. She seems much healthier and there is little trace of the debilitating limp that had her depressed and hurting. Thank you so much for a wonderful product and for giving Shasta some pep in her life again!
