So sorry to hear this Brian. My condolences. It seems like you have had River forever so I know how hard this must be for you and your mom. He was such a love. I would scratch his backside and he definitely wouldn't want me to stop! He was a beautiful dog with a warm soul. He shed like crazy, but he was worth it. You gave him a wonderful life. He couldn't have asked for a better dad. Sending you my prayers.
