not sure why you should need breed specific dog food, sounds rather a money spinner to me. Eukanuba was one of the original 'specialist' foods that could only be sourced through your vet. It was incredibly expensive compared with any other but you didnt have to feed a lot and the difference in the poos were considerable, small, non smelly and a good consitency (yuck!). I have no idea what it is like now as I have never used it on my dogs and only have experience of it with dogs that came into my boarding kennels.
