Aww, I saw the pictures in your album and I am shocked how much the groomer shaved Princeton's body. At least they left his sweet face. The color of his body is probably what my Teddy would look like if I shaved him.
His hair will grow back quickly. If your weather suddenly turns warm in the next couple weeks, be careful with him in the direct sun. I would keep a tshirt on him to prevent sunburn.
You are a great mommy for carrying him around and giving him extra loving.
