Protect your floors and your pup with Pet Life Unlimited Health Tracker Dog Pads. These pads feature a pH-responsive dye woven through them, which reacts to your furbaby's urine pH and changes the top sheet color. The sheet color quickly changes and never disappears, so you can check back anytime. You can use the colors to detect common health issues like UTIs and bladder and kidney stones before your best friend even feels the symptoms. Just put down one pad a day wherever your dog pees to establish your pup's baseline and then track any changes to keep a close eye on your furry friend's health.
