My GSP is now 14 and was recently diagnosed with Congestive Heart Failure. With that diagnosis comes a lot of medications, including Lasix. On Lasix Sof drinks more water and has to pee A LOT! Since she is older she also sleeps more. These three things don’t always mix and she began to unload her bladder while sleeping on the bed, couch, her bed, etc… I purchased two and they have been a LIFESAVER when it comes to my bed and couch. The liquid will stay near the surface so you can wipe off and sop up. It does NOT go through to under the blanket at all!!! Do not hesitate in buying this blanket. I bought two so far and am considering buying more for my car, her bed, and one just for traveling to other places so I don’t have to bring one of my staple blankets!
