Ironwood Large Breed Review: 29% Protein Dry Dog Food for Large breed adult

Ironwood Large Breed is a large-breed formula with controlled calcium and a bigger kibble. On the numbers it delivers 29% crude protein and 15% fat at 388 kcal per cup, which puts it in the middle band of the dry-food market for large breed adult dogs.

Nutrition at a glance

Protein of 29% sits comfortably above the 22% minimum for adult maintenance and, for most house dogs, above the point where extra protein stops paying for itself. Fat at 15% is the variable that decides how much you feed: at 388 kcal per cup, a moderately active 25 kg dog needs roughly 3.35 cups a day, split across two meals.

Who it suits — and who should skip it

This formula is built for large breed adult dogs that tolerate chicken-based recipes. It is a sensible fit if your dog holds weight easily on moderate portions and has no history of food reactions.

• Good fit: healthy dogs with no diagnosed food allergy and a body condition score of 4–5/9.
• Think twice: dogs with a confirmed sensitivity to chicken meal — pick a novel protein instead.
• Skip: puppies under 12 months unless the AAFCO statement explicitly covers growth.

If your dog has had ear infections, paw licking or intermittent loose stools, resolve that first with a vet-guided elimination trial. Changing bags to treat a suspected allergy usually just moves the problem.

Feeding and transition notes

Start from the bag chart and adjust weekly. As a reference point, a 10 kg adult on this food needs about 1.68 cups a day, a 25 kg adult about 3.35 cups, and a 40 kg adult roughly 4.9 cups.

Transition over seven days in 25% steps. Store the bag sealed, use it within six weeks of opening, and never top up old kibble with new — that is how stale fat at the bottom of the bin keeps getting fed.

Judge Ironwood Large Breed by the numbers and your dog’s body condition, not by the front of the bag: 29% protein at $9.95/kg is mid-market, and the feeding math above tells you the real monthly cost.
