Thanks everyone. I went ahead and called the vet to see if he should be seen. He is still limping, but she said since he is putting weight on the leg it probably isn't too bad. She said to give him until Saturday and if he has not improved she will come in (the vet I like doesn't come in on weekends normally) and see him then. She said if he seems any worse at all to bring him in, and she told me about giving regular asprin because of his size. he's about 65 lbs too. He seems to feel a little better after the asprin. He isn't crying anymore at least (I felt so bad for him).
I know he isn't going to be happy with me. The vet told me no walkies until he is completely healed. he is just to go out and potty and come right back in. He is getting lots of attention though. I took the day off work to make sure he gets lots of loving, and dh is instructed to pick up a good bone on the way home from work.
