Taste Of The Wild (T. O. T. W.) is only one of the product brands manufactured by Diamond Pet Foods, although, in my judgement, it is by far their best product!

This food does have its' own dedicated website with a couple of helpful items, such as the A-Z explanation of the ingredients list (great for us "non food scientist" types!), plus a fairly comprehensive product benefits section.
A Grain Free recipe for all of the T.O.T.W. offerings, and a suitability for all life stages, is stated on the website. There is a feeding guide there also.
These are the main ingredients in a great menu offering;
