I wanted to let you know, our elderly English Setter loves your product. She was a stray, and just showed up at our door. We have had her 13 years. She was diagnosed with multiple tumors and she had about 6 months to live. When her 6 months were up, and she was still around, my husband decided to try your product. She acts like a puppy again. Running and jumping, and trying to play with our dachshund. Something has put a new lease on her life. We are giving you the credit.
