What it sounds like is this pet food company has caught on to what has been successful in North America, find a niche or stage or whatever, create a label stating what it is supposed to the ultimate for, seal up a bag of kibble and market, promote and publicise. What is this latest? a weaning formula?
Royal Canin - dang, they have so many types of food, 15 SKU's is not surprising. They are one of the first to make breed specific foods - so how cool is it to go in and buy a food for one's Yorkshire Terrier that is labeled for Yorkshire Terriers?

Guess I have to buy a bag of Maltese food for my Maltese too, they certainly couldn't eat the same food now could they? Nutro a few years back had special formulas for each of the AKC recognized groups - Sporting, Hounds, Working, Terriers, Toys, Non-Sporting and Herding. Now in the Non-Sporting group there is an eclectic collection of breeds to say the least. How a Dalmatian and a Lhasa Apso are going to benefit from the same bag of food "specialised" for this group - I don't figure. There are dental foods, weight management foods (one company has Weight Management I and Weight Management II), senior Foods, puppy foods - generic puppy food, small breed puppy food, medium breed puppy food, large breed puppy food. Maintenance, performance, joint care, skin and coat, lamb, chicken, beef, fish - white fish, salmon, turducken, grammy's pot pie, cowboy stew, small bites, regular bites, large bites, vegetarian, bison, venison, rabbit ... just another day on the dog food aisle at even some grocery stores in the US and most certainly at any pet supply store. So while in the US at least we don't have a "junior" labeled food, we've got everything else and then some, you'll have to forgive us Yanks for being rather blase' over this latest marketing gimmick of Nutrience pet food.
You know I just have to wonder what Michael would do if he'd walk into some of the large pet supply chains and see the selection we have in North America. I'm not sure if he'd have a coronary or reach Nirvana?
