Excellent product
I have used this particular product for more than 4 years, although one of my dogs has been fed on Arden Grange for 7 years. The "Senior"has the same calories as the "light", but has those little extras older dogs need. In my last bag I noticed the size of the kibble had been reduced, which now makes it very easy for my new 14.5 year old foster dog to eat. Obviously palatable, no upset tummies, healthy happy dogs.
