Hi zarah - couldn't agree more :)
I have been thinking further on this thread and the addition of maize to this diet in particular. I totally concur that it is strange to add an ingredient which is known by the veterinary profession to be high on the intolerance list

Perhaps there are too few reported cases of suspect allergens supplied
directly to pet food manufacturers ..... By virtue of the wealth of varied diets in both general sale and prescription only forms, clearly pet food manufacturers are aware of the increased diagnosis of intolerances/allergies in recent years but are they
completely au fait with exactly which ingredients are commonly found to be a problem? I think perhaps not.
Not so long ago chicken or beef were the common meat products to complete foods then "sensitive systems" were acknowledged and catered for by the introduction of lamb and turkey. With intolerances growing to embrace these newer additions, pet food companies duly responded and we now have options of white fish, salmon, duck, venison, pork and very possibly more besides - certainly that is the case in America.
Similarly rice, wheat and corn, the one time main bulking products, no longer have exclusive status as oats, potato and tapioca are finding their way more regularly into different ranges - again, an acknowledgement by the pet food manufacturers that there is a genuine
medical need to move away from providing a traditional grain mix as staple ingredient.
In an ideal world, when introducing a potentially novel protein source to their ranges, manufacturers would do so with an equally novel bulking property or at least providing a couple of different choices. But as with everything else of course they need to "test" their market.
Although I now feed a home prepared diet to my dogs, were I looking for an alternative complete this would not be for me because of the use of maize - however, as has been pointed out, even dogs (or people) suffering with intolerances to many grains / carbs etc., will not necessarily be intolerant to maize. Personally, IMO, by the addition of maize they have undoubtedly narrowed their market - but how will they get to know that? How many of us regularly correspond with manufacturers giving them feedback on their products? Do all of our vets treating dogs with intolerances ensure that they pass on a list of the proven and also highly suspect ingredients causing serious problems for their patients?
Unfortunately, as I see it, although the pet food market is trying to respond by providing more variation in their main ingredients, for some reason precious few complete foods have the absolute minimal ingredients - it is insufficient IMO to bring out a (hopefully) novel protein and lump it in with mainstream carbs, grains, etc. Owners with genuine medical causes for concern who are looking for novel diets are definitely not best served by a change in the protein source served up with "all the usual suspects" :(
Fair play to those companies which at least are trying. Perhaps things would progress better still if as individuals and through vets we actively ensured that manufacturers were up to speed with what the ever developing needs (and no-goes) for our pets are!
