I Am Giving My Golden Retrievers K9 Fido Vite And

I am giving my golden retrievers K9 Fido vite and I would like to know if Nupro would be a better choice. My male is 12 years and my female is 8. Copper the male is on thyroid medication and quelling. Mya the female is on dasaduin. I feed them blue buffalo kibble and I make dog food from rice green beans carrots sweet potter and chicken. I want to be sure they are getting the nutrients they need, hence the supplement.
