Our dog was diagnosed with inflammatory bowel disease when she was just a puppy. We spent thousands of dollars at the vets trying to find the proper treatment. She was on several prescription meds including steroids and antibiotics which caused many side effects.. We were finally able to wean her off all her meds thanks to these supplements and a diet of hydrolyzed protein. She also had several bald patches because of the steroids and now these supplements are helping her fur grow back. If your dog suffers with skin or digestive issues give these supplements a try.
