Overview
Blue Buffalo's Natural Veterinary Diet W+U dry dog food targets weight management and urinary care together, in a 22 lb bag of chicken flavor kibble for adult, large-breed dogs. It requires a veterinarian prescription to purchase.
This is a therapeutic formula, not an everyday kibble, built around a specific pairing of goals: helping an overweight dog trim down while also supporting urinary health. It is corn, wheat and soy free, and uses pea protein, flaxseed and dried chicory root among its ingredients, with taurine and added amino acids.
- 22 lb bag, chicken flavor
- Formulated for adult, large-breed dogs
- Corn-free, wheat-free, soy-free, preservative-free
- Contains taurine, DL-methionine and L-threonine
Who it's for
Suits large-breed adult dogs under veterinary supervision for weight and urinary issues at the same time. Not appropriate to buy without a prescription, and not a general-purpose food for a healthy dog.
Strengths and trade-offs

Performance notes
The formula leans on pea-based proteins and fiber along with flaxseed and dried chicory root, with taurine, DL-methionine and L-threonine included to support the urinary care side of the diet. Blue Buffalo markets it strictly as a veterinary diet, sold in a single 22 lb bag with no over-the-counter substitute in this listing.
