I have a Great Dane and my mom is taking care of my brother’s rottie. We used to have both of them on Dasuquin with MSM for large breed dogs made by Nutramax. http://www.nutramaxlabs.com/dog/dog-joint-bone-health/dasuquin-for-dogs It worked very well but was very pricey. Last time I bought it on Amazon it was $80 for the 150ct bottle. They come in beef flavored chewable tablets which makes it easy to give. The rottie ate them like treats but my Dane was picky and I had to crush them up in his food. Now, I buy the same components (glucosamine, MSM, chondroitin, and ASU) from swansonsvitamins.com and give them to my dog crushed in his food. It costs me about $25/month now instead of $64 (I was giving 4 tabs per day so the 150ct lasted about 5 weeks).
