Hi, I have a 9 year old Golden Retriever and am trying to do some research into different brands of food that are brought out in ranges for Seniors. I am currently feeding her Supercoat Light and Mature and although she is going well on it, I am a little concerned by the low level of Protein (17%). I realise that the lower levels of protein and fat are as a result of the higher fibre for the 'light' part. I have seen that most other brands, ie Advance, Hills, Eukanuba etc have higher protein levels (about 26%). I have been thinking I might go with Advance Senior or Hills Science diet mature because I am somewhat limited by cost. I would really appreciate any advice anyone can give me becuase it all gets a little overwhelming the more research I do
