I got a few more things to do. I've only had to buy the lumber and screws. Everything else been found around the yard. Gonna hook up a MH1210 digital thermometer. Not the nicest but functional.
Very nice pen. My pens are like that but I use the Kane heating pad and rheostat on my pups. Change the temperature as they get older. Pad works good for the older dogs in the winter keeping them warm. Good luck raising your pups.
