Tall Tails -Waterproof Dog Pad - LG - 33 in. X 21 in.

I bought this at the store for my elderly dog who sadly has renal disease and so has accidents sometimes upon waking. He sleeps with me so I needed something that would protect my mattress. It is indeed waterproof, his urine has not soaked through, however, I gave it only 4 starts because it's rather small. I was hoping for more a "throw blanket" size but even the large is really about as big as one of my couch cushions. The material isn't too bad but I do put a blanket over it for him to make it a little softer for him. It does the job and keeps him in bed with me, just wish it were a little bigger.
