When I compare dog food, I look at more than the name on the bag. I want to know what is in the food, how easy it is for dogs to eat, and what type of dog may fit the recipe best. For this Natural Balance vs Purina Pro Plan review, I compared two lamb and rice dry foods. The Natural Balance recipe uses lamb as its first meat source and keeps the recipe fairly simple. The Purina Pro Plan Sport 27/17 Small Bites recipe is made for active dogs and has a higher protein and fat level. I like both foods, but they serve very different needs. If you want a simple answer, Natural Balance is my pick for dogs that need a simpler recipe, while Purina Pro Plan is my pick for active dogs that need more fuel.
Natural Balance Limited Ingredient Lamb & Brown Rice Review
I found Natural Balance to be a good choice when I wanted a dog food with a simple recipe. The lamb and brown rice recipe uses lamb as the first ingredient and has one main animal protein source. I liked this setup because it made the food easier for me to understand when I was checking the label. The brown rice also adds fiber, which can be useful for normal digestion. I think this food makes the most sense for adult dogs whose owners want a simple daily meal without a very high protein target. For a dog with food needs that call for a limited recipe, I would put this one high on my list to check with a vet.
Pros
- Simple recipe: I liked that the food has a clear main protein source instead of several meat types.
- Lamb first: Seeing lamb first on the ingredient list gave me a clear idea of the main meat used.
- Brown rice: I liked having a grain source that can add fiber to the meal.
- No corn, wheat, or soy: This made the recipe more appealing to me when looking for a food with fewer common grain and soy sources.
- Adult dog focus: I found the recipe easy to consider for normal adult feeding needs.
Cons
- Not for every dog: I would not pick it just because the ingredient list looks simple. Each dog has different food needs.
- Not a high-fuel sport food: I would look elsewhere for a very active dog that needs a high calorie and high protein meal.
- Lamb may not suit every dog: A dog can still react badly to any food protein, so I would watch for changes after a food switch.

Is the Natural Balance Lamb & Brown Rice Good?
Yes, I think it is a good option for the right adult dog. I like it most when the goal is a simple food plan rather than a high-fuel diet. The lamb gives the recipe a clear meat source, while brown rice gives the food a grain-based source of fiber. I would consider it for a dog that does better on a short ingredient list. I would not choose it only because it says “limited ingredient,” since the full food label still matters. For dogs with known food problems, I would ask a vet before making the switch.
My Recommendation
I recommend Natural Balance to owners who want a simple adult dog food with lamb and brown rice. I think it is a better match for a normal adult dog than for a very active working or sport dog. I would also consider it when I want to avoid corn, wheat, and soy in the recipe. If my dog needed a higher protein and higher fat food for hard daily activity, I would look at Purina Pro Plan instead. I would always change dog food slowly and check with my vet when a dog has a health or food issue.
Purina Pro Plan SPORT 27/17 Lamb & Rice Review
Purina Pro Plan Sport 27/17 feels much more focused on active dogs. The recipe has real lamb as the first ingredient and provides 27% protein and 17% fat. I noticed the difference right away when I compared the nutrition goals with a normal adult food. The kibble is also made in small bites, which can be useful for dogs that prefer smaller pieces. The recipe includes live probiotics, glucosamine, EPA, and other nutrients aimed at active dogs. I see this as the stronger choice when the main goal is energy, muscle support, and daily activity rather than a simple ingredient list.
Pros
- High protein: I like the 27% protein level for active dogs that need more fuel.
- Higher fat: The 17% fat level gives this food a clear focus on active daily needs.
- Small bites: I found the smaller kibble size useful for dogs that do better with little pieces.
- Joint support: The recipe includes glucosamine and EPA, which are useful features to see in an active-dog food.
- Live probiotics: I like that the recipe includes live probiotics for digestive and immune support.
Cons
- More complex recipe: The ingredient list is much longer than Natural Balance, so it may not suit owners seeking a simple recipe.
- Higher calorie load: I would watch portions closely for dogs that are not very active.
- Not ideal for every dog: A high-energy recipe is not automatically better for a dog with low daily activity.
Purina Pro Plan SPORT 27/17 Overview
| Feature | Details |
|---|---|
| Brand | Purina Pro Plan |
| Recipe | SPORT 27/17 Small Bites Lamb & Rice |
| Main Protein | Lamb |
| Protein | 27% |
| Fat | 17% |
| Kibble | Small bites |
| Bag Size | 37.5 lb |
| Best For | Active dogs and working dogs |
| Main Focus | Energy, muscle, and active daily needs |
Is the Purina Pro Plan SPORT 27/17 Good?
Yes, I think it is a strong choice for an active dog. The 27% protein and 17% fat numbers make its goal very clear. I like that it also adds live probiotics and nutrients such as glucosamine and EPA. The small kibble can make meals easier for dogs that like little bites. I would be more careful with portions for a dog that spends most of the day resting. For an active adult dog, though, this recipe makes much more sense than a basic low-energy food.
My Recommendation
I recommend Purina Pro Plan SPORT 27/17 for owners with active dogs that need more energy in their daily food. I would consider it for dogs that run, train, work, or stay active for long periods. I would not choose it just for a low-activity house dog without first checking the feeding amount and calorie needs. The food is more focused on performance than simple ingredients. If my main goal were a shorter ingredient list, I would choose Natural Balance instead.
Natural Balance vs Purina Pro Plan: Quick Comparison
Before comparing every detail, I see a clear split between these two foods. Natural Balance puts more focus on a simple recipe and a limited ingredient approach. Purina Pro Plan Sport puts more focus on protein, fat, and fuel for active dogs. That means there is no single winner for every dog. The better food depends on what your dog does each day and what your vet says your dog needs.
Ingredient Simplicity: Natural Balance vs Purina Pro Plan
Winner: Natural Balance — 9.6/10
Natural Balance wins this part for me because its lamb and brown rice recipe has a much simpler goal. I found it easier to read the label and understand the main food sources. This makes it more appealing when I want a basic recipe.
Purina Pro Plan uses a longer list because it adds more nutrients for an active diet. That can be useful, but it makes the food less simple.
Protein and Energy: Natural Balance vs Purina Pro Plan
Winner: Purina Pro Plan — 9.8/10
Purina Pro Plan clearly wins here. Its Sport 27/17 recipe provides 27% protein and 17% fat. That gives it a much stronger focus on active dogs.
Natural Balance is better suited to normal adult feeding. I would not expect it to give the same level of fuel as the Sport formula.
Digestive Focus: Natural Balance vs Purina Pro Plan
Winner: Natural Balance — 9.4/10
I prefer Natural Balance when the main goal is keeping the recipe simple. Brown rice gives the food a useful grain source, and the limited ingredient design may appeal to owners who want fewer main food sources.
Purina Pro Plan also has a digestive angle because it includes live probiotics. I just see its main purpose as active nutrition rather than a simple diet.
Active Dog Support: Natural Balance vs Purina Pro Plan
Winner: Purina Pro Plan — 9.9/10
Purina Pro Plan is the clear winner for active dogs. Its protein and fat levels are made to support a high-energy lifestyle. It also includes glucosamine and EPA.
Natural Balance can still feed an active dog, but I would look at the dog’s total needs before using it as a sport-focused food.
Everyday Value: Natural Balance vs Purina Pro Plan
Winner: Natural Balance — 9.5/10
For a normal adult dog, I like the simple purpose of Natural Balance. I do not need to pay for a sport-focused recipe if my dog spends most of the day at home.
Purina Pro Plan makes more sense when the extra nutrition is useful. For an active dog, the higher cost may be easier to justify.
