Overview
["This 22 lb bag of chicken flavored kibble is built around peas, pea protein, pea fiber, and flaxseed, with taurine, DL-methionine, L-threonine, and dried kelp rounding out the ingredient list. It's labeled corn free, preservative free, soy free, and wheat free, and the title notes that a veterinarian prescription is required.", "Blue Buffalo positions this as a dual purpose formula, built for weight management while also supporting urinary health, which is a useful combination for dogs juggling both concerns rather than needing two separate diets. It's sized for all breed sizes rather than one specific weight class.", "At $99.98 for a 22 lb bag, it's priced in line with other prescription weight and urinary formulas. With 179 reviews averaging 4.6 stars and roughly 50 bought in the past month, it has a smaller but positive track record among owners managing these combined concerns."]

Performance notes
The pea and flaxseed based recipe leans on plant proteins and fiber rather than a single animal protein source, which Blue Buffalo pairs with taurine and amino acids like DL-methionine and L-threonine, ingredients often included in formulas targeting heart and urinary tract support.
