orijen is a really good food.... eukanuba is one i would avoid. if you find orijen is too expensive, arden grange is just as good, but less expensive. burns is a good food for overweight dogs as it has a high rice content.
basically avoid foods full of additives or preservatives, generally foods heavily advertised on telly eg baker, pedigree, eukanuba
avoid cereals such as maize as these cause biscuits to swell unless soaked beforehand
your best bet i would think would be orijen and you can mix any of the pouches, they are all good to excellent in quality: IMO natures menu is best, JWB next then Nature diet.
but apart from eukanuba, i think youve chosen really good foods. when all said and done, whatever suits your dogs.
one of mine thrives on raw the other goes like skin and bone on raw, yet raw is the preferred choice for many, and its my preference because i know what they are getting, but just not possible with one of them
