I am currently feeding my 65lb 10yr old Amstaf Kirkland Senior dry dog food and have been supplementing with a liquid glucosemine formula for 3 weeks now. Her coat is rather dull and I would like to know what I can do to change that via her diet. If I could change foods to one that included the reccomended dose of glucosemine and something for her coat, I would... but I haven't found anything that would help. I am not interested in going raw.. but would consider raw supplements. Help?
