Frankly, jensol01, any high-quality food would probably be better for your baby.
I would start a glucosamine/chondroitin supplement if he's not on one and cut back on the amount of food so that he loses weight. Excess weight is very hard on joints. We have had multiple dogs over the years with joint problems--mostly we just keep their weight at light normal, make sure they get moderate, low-impact exercise (swimming is great for joint problems if your dog likes water), supplement with glucosamine/chondroitin, and treat with anti-inflammatories as needed. Often, joint problems can be managed well enough to minimize the need for pain meds.
