Not such a good Saturday

I got a puppy not long ago.I named her troubles because she was alway's getting into trouble.She had a ton of energy and loved to play.If me or the kids took off running through the yard troubles would be right on our heels.Every night I would go out and play with her just me and her no kids or other dogs.Last night was no different.I went out,we played,I gave her fresh water and food,told her go lay down and I would see her in the morning.Well this morning there was no playing.The poor dog was dead.She was fine yesterday so why dead today?I'll sure miss that dog.
