Blue Buffalo W+U (Weight Management + Urinary Care)

Blue Buffalo Natural Veterinary Diet Weight Management and Urinary Care

In this product, Blue Buffalo has created a recipe which promotes weight loss, curbs hunger and supports urinary health, when advised by veterinarians.

LifeSource bits, which are packed full for multivitamins, minerals and antioxidants, have been added to help improve the immune system and create a healthy oxidative balance. They are cold-formed in the manufacturing process to ensure no heat destroys the nutrients in them.

But that's all secondary to the main reason of this formula, weight loss and urinary health. By restricting the levels of fat and calories while increasing fiber, this recipe makes your dog feel fuller for a longer period of time and thus the otherwise extra calories and fat avoid being consumed.

On top of that, formulated into the product are controlled mineral levels of minerals like magnesium and sodium to support your dogs urinary health.

Blue Buffalo's Natural Veterinary Diet W+U is by all standards a quality dog food, earning 4.5 out of 5 paws on its nutritional analysis and ingredient list.

Controlled levels of fat and calories to aid weight loss.

High in fiber to keep dogs feeling fuller for longer.

Added LifeSource bits for a healthy immune system.

Controlled mineral levels to support urinary health.

Made without any grain, which some pet parents choose to avoid.

No artificial flavors, colors or preservatives.

Below we will look at some of the main ingredients which contribute to these properties.

Ingredient Analysis

Quick Peek of What's Inside

  • Quality

    Deboned Chicken, Chicken Meal, Flaxseed

  • Questionable

    Dried Tomato Pomace, Garlic, Alfalfa

  • Potential Allergens

    Deboned Chicken, Chicken Meal, Turkey Meal


In the United States, the guidelines for pet food ingredient labels are established by the Association of American Feed Control Officials (AAFCO) and individual state regulations.

The AAFCO requires that ingredients must be listed in descending order of weight (including water weight). This means that ingredients that appear at the top of the ingredient list — typically the main proteins, carbs, and fat sources — are present in higher amounts by weight in the food than items at the bottom.(2)

Although it is difficult to determine how much of an ingredient is actually in the food (due to high water content in meats and vegetables), you can assume that the first few ingredients are in the highest amounts. Therefore, the first few ingredients of a dog food can tell you a lot about the quality of the product.


Since ingredients on dog food labels must be listed in descending order by weight, analyzing the first five ingredients has become a popular way of sifting the good from the bad at a glance. The Blue Buffalo W+U (Weight Management + Urinary Care) includes the following ingredients. 

Deboned Chicken & Chicken Meal

Chicken, chicken meal and (also turkey meal) are all the meat-based protein ingredients in this diet. All three are very easy to digest and excellent for sensitive stomachs. It is worth considering that dehydrated, ground meat, in the form of meals, contain approximately 300% more protein per gram that their original fresh protein, and therefore the meals in this recipe probably will contribute the most protein to the recipe.

Pea Starch, Peas, & Pea Protein

Peas, pea starch, pea protein (and also pea fiber) have been added to provide minerals, vitamins and most importantly fiber. Fiber helps regulate the water content in the guts to keep the stools as regular as possible. They are also an excellent source of protein, with a content of about 25%, so when judging the protein content from the meat ingredients, this should be considered.

Other Ingredients

Flaxseed has a high concentration of omega-6 and omega-3 fatty acids. When they omegas are in a ratio of 3:1, they have potent anti-inflammatory effects, which is excellent for dogs with arthritic joints or itchy, allergic skin [3].

Cranberries and blueberries are sources of antioxidants, which help improve the immune system by fighting free radicals which might damage cells.

Cranberries also play a role in bladder health through acidifying the urine and stopping bacteria from being able to adhere to the bladder [4].

A natural prebiotic is chicory root. This means it enhances the effectiveness of the probiotics in the gut, which help fight off any bad bacteria which may enter.

Potatoes are a carbohydrate which are packed full of vitamins B and C to boost the immune system.

Carrots and sweet potato are both carbohydrates which are high in vitamin A; an excellent source for healthy skin, coat, eyes, nerve and muscle function.

A member of the Allium family, garlic, has been included in the recipe, as garlic is an effective anti-oxidant. It helps prevent cancer and improves the immune system, however in large doses it can be toxic and cause Heinz body anaemia and stomach sensitivities [5].

Also, to aid joints, turmeric reduces inflammation for dogs suffering from arthritis. It also increases lipase enzymes to aid in digestion of food [6].

To help keep the thyroid functioning well, kelp is an excellent source of iodine. It also contains plenty of minerals, vitamins and anti-oxidants, which improve the immune system.

Lactobacillus and enterococcus are probiotics, which are good bacteria which naturally occur in the guts and aid digestion. They also compete with, and fight off the bad bacteria which may enter with certain foods.

Yucca extract helps reduce wind build up and gassiness in the guts. This helps keep the dog comfortable, and the house smelling fresher!

Finally, the recipe has added vitamins and minerals to balance the meal and make it ideal for weight management and urinary health.

Nutrition Analysis

ⓘ All the product information on this page is based on data collected from the manufacturer's product website on April 2nd 2019. If something changed, please let us know.

Fatty Acids

0.5% (min) Omega-3 & 2.0% (min) Omega-6

Major sources of energy. The Dog Food Project’s Sabine Contreras states: “Independent researcher Dr. Doug Bibus (formerly University of Minnesota) completed a fatty acid study with dogs and recommends a ratio between 2:1 and 4:1. Personally, I believe that a quality food should contain a ratio of at least 7:1, the lower the better, especially if skin and/or coat problems are present. When my dog suffered from severe flea allergy dermatitis I switched to a food with a ratio of 2.5:1 and had great results within just a few weeks.”

Metabolizable Energy

3,074 (ME in Kcal/kg)

ME is defined as the amount of energy available from pet food once the energy from feces, urine, and combustible gases has been subtracted. Essentially, ME is the energy left for your pet's body to use once all digestion is complete.

Note: That some nutritional percentages reported are only estimated values, and are indicated as such as (est). Each dog food manufacturer is required by law to publish a Guaranteed Analysis, which defines each product’s maximum values of fiber, moisture and ash in addition to the minimum values of protein and fat contained within. Exact nutritional percentages are not available and hence all calculated values (including carbohydrate percentages and calorie amounts) are determined using these minimum and maximum published values and therefore may differ from actual values.

    How does this food compare to Hills Prescription Science CD Multicare formula which my vet told me to feed
    my dog that has reoccuring UTI’s. The protein level is higher than Hills as well which is 18% but I don’t like the
    corn meal ingredient. Debating whether to change to Buffalo or not.
