Yep! Of course Candy is right! Ice Cubes are great! I also put his tennis balls in the freezer so they were nice and cold when Cody teethed. I think they wind up in poopy-land but far be it from me to check it out! Believe it or not, I actually missed those pesky, sharp little needle baby teeth! It meant he was growing and I really wanted him to stay a puppy a little longer!
