Review on Enhance Joint Health and Flexibility for Dogs and Cats with Rx Vitamins for Pets MegaFlex - Glucosamine & MSM Formula - 600g Powder by Elizabeth Morton

Well the first week was great but then his bowel movements became loose until they were completely loose. I stopped the supplement and his bowel movements are back gone normal The vet recommended another brand that doesn't do this but is also in 'healing' form so you have to factor in those extra calories since he's 11, but it's definitely worth it since his stool is with his new supplement is normal I was relieved the first day after taking it I was amazed So if your pet is young (my dog is 11 years old) and has an upset stomach (can handle dry kibble) this might be for you want to try.
