Dry Food Formulas For Older And Smaller

[chuckie500]

They have run out of the fish formula Eaglepack I usually use so I bought a pack of the small breed formula (mine are 8.5kg and probably only just fit into the category). I was wondering if any one else has used this?

And also what's the difference in the proportions of things for small breeds' food and also the seniors' foods. I notice there is nothing for a small breed senior.

I use dry food for about 40% of their diet, but should i feed less fat as they get older or what?

Thanks.
