We’re Pet Lab Co. - a Company Built for Pet Owners, by Pet Owners. Pet Lab Co. Is an Important Venture for Me, but Unfortunately, for A Heartbreaking Reason. a Few Years Back, I Had to Make the Difficult Decision Every Owner Dreads – to Put My Dog Krystal to Sleep. I Had 17 Amazing Years with Krystal, and I Know She Lived a Long and Happy Life, but During the Last 4 Years of Her Life, She Experienced Arthritic Pain and Struggled to Walk. I Felt a Lot of Guilt Around Whether I Could Have Done More in Terms of Supplementation to Support Her Properly.
