Petbrosia custom-designs petfood for the unique nutritional needs of each pet. Pet owners visit Petbrosia.com and create a profile for each of their pets by entering key information, such as their breed, age and weight. The company then uses a series of proprietary algorithms and a patent-pending process to create a custom blend that meets the specific nutritional needs of each pet. Petbrosia food contains real free-run, antibiotic and hormone-free chicken as the first ingredient, "super" fruits and vegetables, prebiotics and probiotics to support healthy digestion and strong defenses, and added glucosamine and chondroitin for healthy joints. Petbrosia is without corn, soy, wheat gluten or by-product meal.
