Sully is almost at his 9 month ampuversary.  He is still doing great, although some days he moves slower than others.  He is a lazy Dane, so it is sometimes hard to gauge when he is hurting or when he is just enjoying laying in the sunshine refusing to get up.  I do know that some days, when he gets a little too ambitious and decides to run laps around our house, he wakes up stiff and sore the next morning.  I want to do something to help keep his one front leg strong, because it is holding a lot of weight (he is still a 125lb dog!)  I called my vet's office asking about a joint supplement or something that I could give Sully daily, but they told me that they would give me dasuquin once I felt like the the deramaxx is no longer working.  This answer sort of confused me because I only give him the deramaxx on mornings when he seems to be in hurting, not daily, as I thought it was an anti inflammatory pain med and.  I was under the impression that dasuquin was more of a daily supplement and not a pain medication.  Are there any daily joint supplements that any of you have used that you would recommend? Also, I have seen a lot of people on here talk about rimadyl for pain for their pups.  Is rimadyl different/better than deramaxx?  Thanks for your help!
