Finding the right food for a small dog can be surprisingly difficult.
Smaller dogs have smaller stomachs, different calorie needs, and—sometimes—very particular eating habits. If your dog also has a sensitive stomach or recurring skin issues, the number of choices can become overwhelming.
That's where Purina Pro Plan Sensitive Skin & Stomach Small Breed Salmon & Rice comes into the picture.
This formula is made specifically for adult small-breed dogs weighing up to 20 pounds. It uses salmon as the first ingredient, includes prebiotic fiber and guaranteed live probiotics, and is made without corn, wheat, soy, or poultry by-product meal.
But is it actually a good choice for a small dog?
I looked at the current ingredient list, guaranteed analysis, calorie content, feeding recommendations, and the features Purina highlights for this formula.
Quick answer: Purina Pro Plan Sensitive Skin & Stomach Small Breed Salmon & Rice is a strong option to consider if you have an adult dog under 20 pounds and want a salmon-based formula designed around digestive and skin-and-coat support. The recipe provides 28% minimum protein, 17% minimum fat, prebiotic fiber, live probiotics, and 465 kcal per cup. It is also formulated without corn, wheat, soy, and poultry by-product meal.

What Is Purina Pro Plan Sensitive Skin & Stomach Small Breed?
This is not simply the regular Pro Plan Sensitive Skin & Stomach recipe in a smaller bag.
It's specifically formulated for small adult dogs under 20 pounds.
Purina describes it as a highly digestible formula with salmon as the first ingredient, easily digestible oatmeal, natural prebiotic fiber, and guaranteed live probiotics.
The formula is also designed around the nutritional needs of active small dogs, which explains the relatively concentrated calorie content.
That's important because small dogs don't need the same amount of food as large dogs, and their meals need to provide enough nutrients and energy in a relatively small serving.
Purina Pro Plan Small Breed Sensitive Skin & Stomach Ingredients
The current ingredient list begins:
Salmon, rice, barley, canola meal, fish meal, dried yeast, beef fat preserved with mixed-tocopherols, oat meal, salmon meal, pea protein, natural flavor, sunflower oil, fish oil, dried chicory root...
There are several things worth noticing here.
Salmon Is the First Ingredient
This is probably the biggest selling point of the formula.
Salmon appears first on the ingredient list.
For owners specifically looking for a fish-based food, that's useful information.
The formula also contains fish meal and salmon meal later in the ingredient list, giving the recipe additional fish-derived ingredients.
But, as with any dog food, I wouldn't judge the entire recipe simply by looking at the first ingredient.
The complete nutritional profile matters much more than one ingredient in isolation.
Rice and Barley
Rice is the second ingredient, followed by barley.
These ingredients provide carbohydrate sources within the overall formula.
The recipe is therefore not grain-free.
That's worth making clear because some shoppers see "Sensitive Skin & Stomach" and assume that means a grain-free food.
It doesn't.
Instead, this particular recipe uses grains that Purina includes as part of the overall formulation.
Oatmeal for Digestive Support
Oatmeal is also included in the recipe.
Purina specifically describes the oat meal as easily digestible and gentle on the digestive system.
That's consistent with the overall purpose of the formula.
However, "gentle on the digestive system" shouldn't be interpreted as a guarantee that every dog with digestive problems will tolerate it.
Dogs can react differently to the same food.
No Corn, Wheat, or Soy
One of the clearest differences between this recipe and many conventional dog foods is what it doesn't contain.
Purina states that the formula is made without:
- Corn
- Wheat
- Soy
It also doesn't contain poultry by-product meal.
This can make the formula particularly attractive to owners who are intentionally looking for those characteristics.
That doesn't mean corn, wheat, or soy are automatically bad ingredients for every dog.
It simply means this particular recipe doesn't use them.
No Poultry By-Product Meal
The absence of poultry by-product meal is another feature Purina specifically highlights.
The recipe instead relies heavily on fish-derived ingredients, including salmon, fish meal, and salmon meal.
For owners wanting a salmon-focused formula, that's a meaningful distinction.
Guaranteed Analysis
The current guaranteed analysis is:
| Nutrient | Guaranteed Amount |
|---|---|
| Crude Protein | 28% minimum |
| Crude Fat | 17% minimum |
| Crude Fiber | 3% maximum |
| Moisture | 12% maximum |
| Linoleic Acid | 1.6% minimum |
| EPA | 0.1% minimum |
| DHA | 0.1% minimum |
| Calcium | 1.0% minimum |
| Phosphorus | 0.8% minimum |
| Selenium | 0.35 mg/kg minimum |
| Vitamin A | 15,000 IU/kg minimum |
| Vitamin E | 460 IU/kg minimum |
| Omega-3 Fatty Acids | 0.7% minimum |
| Omega-6 Fatty Acids | 1.7% minimum |
Purina's current product information also lists glucosamine and vitamin C among the additional nutritional components.
Is 28% Protein High?
For a dry adult dog food, 28% minimum crude protein is a substantial amount.
That's particularly relevant here because Purina positions the formula as high-protein nutrition for active small dogs.
But protein percentage shouldn't be the only reason to choose a dog food.
A dog's total nutritional requirements, calorie intake, body condition, activity level, and tolerance of the formula all matter.
Probiotics and Prebiotic Fiber
This is another area where the formula stands out.
Purina says the food contains guaranteed live probiotics and natural prebiotic fiber. The older official product label identifies Bacillus coagulans at a minimum of 600 million CFU per pound.
These two concepts are worth separating.
Probiotics
Probiotics are live microorganisms included in a food or supplement.
Prebiotics
Prebiotics are substances that can provide nourishment for certain microorganisms already present in the digestive tract.
This formula includes both.
That doesn't make it a treatment for gastrointestinal disease, but it is a reasonable nutritional feature for a food specifically marketed toward dogs with sensitive digestive systems.
Skin and Coat Support
The formula also contains omega fatty acids.
Purina highlights sunflower oil as a source of omega-6 fatty acids for healthy skin and coat, while fish oil contributes omega-3 fatty acids.
The guaranteed analysis lists:
- 0.7% minimum omega-3 fatty acids
- 1.7% minimum omega-6 fatty acids
Again, there's an important distinction here.
These nutrients can support normal nutrition for skin and coat.
That doesn't mean the food will cure allergies, dermatitis, infections, or unexplained itching.
If your dog has persistent skin problems, the underlying cause should be evaluated rather than assuming a food change will solve it.
Is This Formula Actually for Small Dogs?
Yes.
This is one of the most important things to understand about the product.
Purina's feeding information specifically covers dogs from 3 to 20 pounds, and the product description says it is formulated for small dogs under 20 pounds.
That means this isn't simply a general adult food that happens to come in a small bag.
It's specifically positioned as a small-breed adult formula.
How Many Calories Are in Purina Pro Plan Small Breed Sensitive Skin & Stomach?
The current Purina product information lists:
465 kcal per cup
with a standard 8-ounce measuring cup containing approximately 122 grams of food.
That's fairly concentrated nutrition.
For a small dog, calorie density matters because the amount of food consumed each day is relatively small.
It also means you shouldn't compare feeding amounts between this formula and another dog food without looking at calorie density.
How Much Should You Feed?
Purina provides the following starting guidelines for adult dogs:
| Dog Weight | Daily Amount |
|---|---|
| 3–12 lb | 1/3–1 cup |
| 13–20 lb | 1–1 1/4 cups |
The corresponding approximate amounts are 40–122 grams for dogs weighing 3–12 pounds and 122–153 grams for dogs weighing 13–20 pounds.
These are starting points rather than exact prescriptions.
Purina recommends adjusting the amount according to factors such as age, activity, environment, and body condition.
That's especially important with small dogs because even relatively small changes in daily food intake can have a noticeable effect on body weight.
How to Switch Your Dog to This Food
Don't rush a food transition just because your dog seems excited about the new bag.
Purina recommends transitioning over 7–10 days, gradually reducing the old food while increasing the new Pro Plan formula.
A gradual transition can help reduce the chance of dietary upset.
For a dog with a sensitive digestive system, taking the transition slowly makes even more sense.
If digestive problems appear or become severe, don't simply continue changing foods repeatedly. Talk to your veterinarian.
What I Like About This Formula
There are several things that stand out positively.
Salmon First
Salmon is the first ingredient, making the formula a logical choice for owners specifically looking for salmon-based nutrition.
Designed for Small Dogs
The formula is specifically intended for adult small dogs under 20 pounds rather than simply being a generic adult recipe.
No Corn, Wheat, or Soy
This is useful for owners who intentionally want a recipe without those ingredients.
No Poultry By-Product Meal
That's another distinguishing characteristic of this formula.
Probiotics and Prebiotic Fiber
The combination makes sense for a formula positioned around digestive support.
High Protein
The 28% minimum crude protein level gives the formula a relatively protein-rich nutritional profile.
Complete and Balanced
AAFCO feeding tests substantiate the formula as complete and balanced for maintenance of adult dogs.
Potential Drawbacks
No dog food is perfect for every dog.
Here are the things I'd consider before purchasing.
It's Relatively Calorie-Dense
At 465 kcal per cup, portion control matters.
A small dog doesn't need a huge amount of food to consume a significant number of calories.
It Isn't a Limited-Ingredient Diet
Although the formula avoids several common ingredients, it still contains a fairly long list of ingredients.
So "no corn, wheat, or soy" shouldn't be confused with "limited ingredient."
It Contains Multiple Fish Ingredients
Salmon, fish meal, and salmon meal are all part of the recipe.
That's a positive for someone wanting fish-based nutrition, but it obviously won't suit someone trying to avoid fish.
It Isn't a Prescription Diet
This is a regular Pro Plan specialized formula.
If your dog has a diagnosed gastrointestinal disorder, confirmed food allergy, or another condition requiring a therapeutic diet, your veterinarian may recommend a different approach.
Is It Good for Dogs With Sensitive Stomachs?
It can be a reasonable food to consider.
The formula combines several features that make sense for this purpose:
- Salmon as the first ingredient
- Oat meal
- Prebiotic fiber
- Live probiotics
- A specialized small-breed formulation
Purina specifically describes the recipe as highly digestible and designed to support digestive health.
But I wouldn't call it a guaranteed solution.
A sensitive stomach can mean many different things.
Occasional mild digestive upset is very different from chronic vomiting, persistent diarrhea, weight loss, or another ongoing medical problem.
In the latter situations, veterinary advice is much more important than simply trying another bag of food.
Is It Good for Dogs With Sensitive Skin?
The formula has several nutritional characteristics relevant to skin and coat health, particularly omega-3 and omega-6 fatty acids.
That makes the nutritional positioning reasonable.
But again, there's a difference between supporting healthy skin and treating a skin condition.
If your small dog is constantly scratching, developing recurrent ear problems, losing hair, or experiencing inflamed skin, don't assume that changing food is enough.

- Contains prebiotic fiber
- No corn
- No wheat

Who Should Consider This Food?
I'd put this formula on the shortlist if you have an adult dog under 20 pounds and you're looking for:
- Salmon-based nutrition
- A small-breed-specific formula
- A recipe without corn, wheat, or soy
- No poultry by-product meal
- Added probiotics
- Prebiotic fiber
- Omega fatty acids
- Higher protein content
- Complete and balanced adult nutrition
It makes particular sense when those characteristics are more important to you than having the shortest possible ingredient list.
Who Might Want Another Formula?
I'd look elsewhere if:
Your dog weighs more than 20 pounds.
You specifically need a fish-free diet.
Your veterinarian has prescribed a therapeutic food.
You want a limited-ingredient diet.
You are trying to avoid all animal proteins except one specific protein source.
Your dog's medical condition requires a diet formulated for a specific disease.
In those cases, the "best" food is likely to be determined by the dog's individual needs rather than the general features of this recipe.
Is Purina Pro Plan Sensitive Skin & Stomach Small Breed Worth It?
For the right dog, I think there's a reasonable case for it.
The formula is more specialized than a generic adult kibble.
It's made specifically for small dogs, starts with salmon, avoids corn, wheat, and soy, includes prebiotic fiber and live probiotics, and provides a relatively high protein level.
The 465 kcal-per-cup calorie density is also worth noting because small dogs don't need large portions.
So if your dog is under 20 pounds and you want this particular nutritional profile, the formula deserves consideration.
The important part is matching the food to the dog rather than choosing it simply because the word "Sensitive" appears on the bag.
Final Verdict
So, is Purina Pro Plan Sensitive Skin & Stomach Small Breed Salmon & Rice a good dog food?
For many adult small dogs, yes.
The formula has several convincing features:
Salmon is the first ingredient, it provides 28% minimum crude protein, it contains prebiotic fiber and live probiotics, and it avoids corn, wheat, soy, and poultry by-product meal. It's also formulated specifically for small dogs under 20 pounds and is complete and balanced for adult maintenance.
Those are meaningful advantages.
At the same time, I wouldn't describe it as a universal solution for dogs with sensitive stomachs or skin.
A dog can have digestive or skin problems for many reasons, and food isn't always the cause.
For a healthy adult small dog that needs or simply suits a salmon-based formula and tolerates the ingredients well, Purina Pro Plan Sensitive Skin & Stomach Small Breed Salmon & Rice is a sensible option to consider.
