Overview

Purina Pro Plan's SPORT 27/17 Lamb & Rice formula in the Small Bites format offers a specialized nutritional solution for owners of active, smaller dogs who need performance-grade fuel. This 37.5 lb. bag marries the demands of a high-energy lifestyle with the physical needs of dogs who prefer or require a smaller kibble size. The recipe is built around a 27% protein and 17% fat ratio, a composition fine-tuned to help optimize oxygen metabolism for increased endurance. By choosing lamb as the primary protein source, this food provides a robust alternative to more common chicken or beef recipes, which can be beneficial for dogs with certain dietary sensitivities. The inclusion of rice provides digestible carbohydrates to help fuel strenuous activity. This formulation doesn't just power your dog through a weekend hike or a competitive event; it supports muscle maintenance and overall health in a package designed for easy consumption by a wide range of breeds.

Key features

  • High-performance 27/17 protein-to-fat ratio to fuel metabolic needs and maintain lean muscle.
  • Crafted with real lamb as a high-quality protein source.
  • Small-bite kibble is easy to chew, perfect for smaller breeds or dogs with a preference.
  • Specifically formulated to support the nutritional needs of active and sporting dogs.
  • Economical 37.5 lb. bag provides excellent value for bulk buyers.
  • Features rice as a digestible carbohydrate for sustained energy.

Pros

  • Offers outstanding value, with a price-per-pound that sits comfortably below the median and average for premium large-bag dog foods.
  • The 27/17 protein and fat content is scientifically formulated for canine athletes and highly active dogs, supporting endurance and muscle recovery.
  • Smaller kibble size makes this performance food accessible to active small breeds like terriers, spaniels, and beagles that might struggle with larger pieces.
  • Lamb-based recipe provides a welcome alternative for dogs with sensitivities or allergies to chicken and beef proteins.

Cons

  • The high-calorie, high-fat nature of this food may lead to unwanted weight gain in sedentary, less active, or older dogs.
  • The 37.5 lb. bag is very large and heavy, which can be difficult to store and handle for individuals with limited space or physical limitations.
  • This is a specialized diet for "sporting" dogs; a typical family pet with moderate daily activity may be better served by a less intense, all-purpose formula.

Best for

This Purina Pro Plan SPORT formula is an ideal match for active adult dogs that require a calorie-dense, high-protein diet to support their energetic lifestyles. It is particularly well-suited for small- to medium-sized breeds engaged in activities like agility, flyball, frequent hiking, or herding. The use of lamb and rice makes it a strong candidate for dogs with sensitive stomachs or ingredient intolerances to other proteins. Its specific "small bites" format also makes it a great choice for any active dog that simply prefers a smaller, easier-to-chew kibble.

Feeding guide

The right amount of food depends on your dog's age, breed, weight, and especially their activity level. As a general guideline, active adult dogs typically require about 1/2 to 1 and 1/4 cups of food per 20 pounds of body weight per day. This total amount should be divided into two separate meals. Because this is a nutrient-dense performance formula, it's critical to consult the official feeding chart on the product packaging for the most accurate serving sizes. Always monitor your dog's body condition, adjusting portions as needed to maintain a healthy weight, and ensure fresh, clean water is always available.

Ingredients & nutrition note

The product is identified as a "Lamb and Rice Formula." Performance-focused dry foods like this Pro Plan SPORT recipe are typically built around a high-quality animal protein, like lamb, to support lean muscle mass. The inclusion of a digestible carbohydrate source such as rice is common in these diets to provide the necessary energy for athletic activity. Complete and balanced dry foods also contain a precise blend of essential vitamins and minerals, as well as fats and oils which contribute to a healthy coat and provide energy. It is also common for foods in this category to include nutrients that support joint health.

Price comparison

With a price of $2.00 per pound, this 37.5 lb. bag of Purina Pro Plan SPORT 27/17 is positioned as a strong value in the premium dog food market. A review of over 140 similar large-bag dry dog foods shows a median price of $2.43/lb and an average price of $2.85/lb. This formula sits well below both of those marks, offering the benefits of a specialized, high-protein recipe from a globally recognized brand at a cost that is more affordable than the majority of its competitors. While it is not a budget food, it represents a cost-effective choice for owners who need performance nutrition and prefer to buy in bulk.

Frequently asked questions

What does the '27/17' on the bag mean?

The '27/17' refers to the minimum guaranteed percentages of protein and fat in the food—specifically, 27% protein and 17% fat. This ratio is higher than typical maintenance diets and is engineered to support lean muscle and provide the sustained energy required by active, sporting, and working dogs.

Is this small bites formula suitable for my large breed dog?

Yes, absolutely. While the 'Small Bites' name highlights its suitability for smaller dogs, many large and giant breed dogs also enjoy or even prefer smaller kibble. It can encourage slower eating and be easier to chew. The nutrition inside the kibble is formulated for active dogs of any size.

My dog is not very active. Can I still feed him this food?

It is generally not recommended. This is a high-calorie, nutrient-dense food designed for dogs with high energy expenditure. Feeding this formula to a sedentary or low-activity dog could easily lead to excessive weight gain and related health issues. A diet with a lower calorie and fat content, such as a recipe from the Purina Pro Plan ESSENTIALS or SAVOR lines, would likely be a more appropriate choice for a less active pet.

Is this a grain-free formula?

No, the product title explicitly lists 'Lamb and Rice Formula'. Rice is a grain that serves as a highly digestible source of carbohydrates for energy. If you are seeking a grain-free option, Purina Pro Plan offers other recipes in their SPORT and other lines that do not contain grains.

My dog has a sensitive stomach. Is the Lamb and Rice formula a good choice?

For many dogs, a lamb and rice formula can be an excellent choice for digestive sensitivity. Lamb is a less common protein than chicken or beef, making it a good option if your dog has an intolerance to those ingredients. Rice is also known for being gentle on the digestive system. However, every dog is an individual, so it's always best to transition to any new food slowly and monitor their response.

How is this different from other Purina Pro Plan formulas?

This SPORT 27/17 formula is specifically part of Purina's performance lineup, targeting the needs of canine athletes with a high protein and fat ratio for endurance and muscle support. Other lines, like SAVOR (for taste and texture) or BRIGHT MIND (for senior cognitive health), are tailored to different priorities. This 'Small Bites' version further refines the SPORT line for dogs who prefer a smaller kibble size.
