Looking to increase Glucosamine for a 5 yr. old French Brittany that was just x-rayed and found some hip issues. I have this dog eating PMI Exclusive lamb and rice. I thought that was a good food for him. I see now that there are far better diets for him. The dog is overweight now, but on a smaller portion now. Should I be trying to find a new food with better Gluc. and chondr. content, or should I not worry about that in the food and add a supliment? I like the idea of natural treats that have alot of gluc. in them. What would some of those be? Thanks, Court
