which complete dry would you say was the better of the two or is there another better still??

Arden Grange the dearer version not the classic, though classic is also good, but having looked at proportions of meat and ingredients I would say the Arden grange range has the best proportion of anuimal protein and is better value ofr money on the breeders scheme.

I think the Prestige is wonderful for Mums and Pups.
