My dog is a senior with arthritis, and we are going to get him the Royal Canin Aging formula. I looked at all the indgredients and there are no by products and hardly any fillers (there is corn gluten) but it has glucosamine and I think it will be very good for my dog. I am feeding him Ol Roy right now and it is a disgusting. I took him to the vet today and they said he needs a new brand, and Royal Canin would be good. I also like Innova, but you can’t find that easy, and we don’t wanna drive a lot for a bag of dog food :/ . Also my cat eats Iams and that sucks too, so I want to switch her to Royal Canin. I know it isn’t the BEST brand, but is it better than Iams and Ol Roy?
here is the website for the royal canin aging formula for dogs.
