He reminds me of my Sam at that age, although Sam was more blond than red at that age. He loved to sleep upside down in people's laps. Sam is still very snuggly to this day, and tries to be a lap dog at 75 pounds.
I don't think he'll be more than 40 lbs. There is a LOT of Dachshund in him. He's hilarious when he runs, his little back legs go faster than his front legs so he runs sideways, I wish I had a video camera to film it.
