Purina Pro Plan Sensitive Skin &: Best Overall for Sensitive Dogs
#1
PurinaSalmon & Prebiotic Fiber
9.2OUT OF 10
Digestive Health9.5
Skin & Coat9.3
Ingredient Quality9.0
Owner Verdict9.0
This is the only food here that tackles both a sensitive stomach and a dry, itchy coat in one bag. The 30 lb size uses real salmon as the first ingredient paired with rice, making it highly digestible for dogs that struggle with loose stools. Prebiotic fiber supports the gut microbiome, while omega-6 fatty acids from the salmon help maintain a healthy skin barrier. Aggregate user reviews report a 4.6 out of 5 star rating, with many owners noting visible improvements in stool consistency within two weeks.
The formula is completely free of artificial colors, flavors, and preservatives. It is designed for adult dogs of all breeds, though the kibble size is moderate which suits medium to large breeds best. The 30 lb bag is a sweet spot for the cost per meal, falling into the mid-range tier for premium sensitive formulas.
Flaws but not dealbreakers. Some owners of very small breeds mention the kibble is a bit large for their teacup pups. You can soak it in warm water for a few minutes to soften it if needed. Also, the bag reseal is basic, so consider a storage container for freshness if you buy the 30 lb size.
If you only need a probiotic boost without changing the main food, the
Purina FortiFlora supplement further down gives you a concentrated powder you can sprinkle on any meal.
⚠Sizing: The 30 lb bag is heavy. Make sure you have a sealed bin for storage, especially in humid climates, to prevent the kibble from going stale.
Pros
- ✓Salmon is first ingredient, a novel protein for many dogs with allergies
- ✓Prebiotic fiber supports digestive health without added fillers
- ✓Omega-6 fatty acids improve coat condition in about 2 weeks
- ✓30 lb bag offers strong value per meal for a premium formula
Cons
- ✕Kibble size is too large for very small breeds like Yorkies
- ✕Bag does not have a strong resealable zipper
- ✕Contains rice, not suitable for dogs needing a grain-free diet
Probiotic Type
Prebiotic Fiber
Best for: Owners of adult dogs with both digestive issues and dry, itchy skin who want a single complete food that addresses both problems.
Purina Pro Plan Complete Essentials Chicken: Best Starter Size for Picky Dogs
#2
PurinaShredded Blend
8.8OUT OF 10
Digestive Health8.5
Skin & Coat8.0
Ingredient Quality9.0
Owner Verdict9.0
This is the best option for owners who want to try a probiotic food without committing to a huge bag. The 5 lb bag is perfect for picky eaters or for dogs that need a gradual transition. It features a Shredded Blend with crunchy kibble and tender pieces, which aggregate reviews show is highly appealing to dogs that turn their nose up at standard kibble. Real chicken is the first ingredient, and live probiotics are included for digestive health.
The 5 lb size is also ideal for travel or for small breed owners who want fresher food. The bag has a resealable zipper, which is a small but welcome detail. The formula is complete and balanced for adult dogs, and owner feedback consistently mentions improved stool quality after the first bag.
Flaws but not dealbreakers. Chicken is a common allergen for dogs, so this is not the best choice if you suspect your dog has a poultry sensitivity. The 5 lb bag is also not the most cost effective per pound if you have a large breed dog that eats a lot.
⚠Compatibility: If your dog has known chicken allergies, skip this one and go straight to the salmon or beef options in this lineup.
Pros
- ✓Shredded Blend texture appeals to picky eaters
- ✓5 lb bag is perfect for trial runs and small breed dogs
- ✓Real chicken is the first ingredient
- ✓Live probiotics support digestive health
Cons
- ✕Chicken is a common allergen, not suitable for all dogs
- ✕Small bag size means higher cost per pound
- ✕No specific skin and coat benefits beyond basic nutrition
Probiotic Type
Live Probiotics
Best for: Owners who want a low commitment trial size for picky adult dogs that enjoy shredded textures in their kibble.
Purina Pro Plan Complete Essentials Salmon: Best Novel Protein for Allergies

PurinaSalmon First
8.9OUT OF 10
Digestive Health9.0
Skin & Coat9.0
Ingredient Quality9.0
Owner Verdict8.5
This is the best choice for dogs that need a novel protein source to avoid common allergens like chicken or beef. Real salmon is the first ingredient, which is less likely to trigger food sensitivities in dogs that have developed reactions to poultry. The formula includes live probiotics for digestive health and the same Shredded Blend texture that picky eaters love. Aggregate owner reviews rate it 4.7 out of 5 stars, the highest in this lineup.
The 5 lb bag is ideal for testing if your dog tolerates salmon well. Many owners report that this food helps with both loose stools and itchy paws. The salmon also provides natural omega-3 fatty acids, which support skin health and a shiny coat without needing added supplements.
Flaws but not dealbreakers. At 5 lb, the cost per pound is higher than the larger bags. If your dog does well on salmon, you may want to switch to the 30 lb Sensitive Skin & Stomach formula for better value. The bag also lacks a strong reseal, so plan to transfer the kibble to an airtight container.
⚠Transition: When switching from chicken to salmon, mix the foods gradually over 7 days to avoid digestive upset from the protein change.
Pros
- ✓Salmon is a novel protein, great for dogs with chicken allergies
- ✓Highest owner rating at 4.7 out of 5 stars
- ✓Shredded Blend texture encourages picky eaters
- ✓Natural omega-3s from salmon support skin and coat
Cons
- ✕5 lb bag is not cost effective for large breed dogs
- ✕Bag reseal is weak, needs a storage container
- ✕Some dogs may not like the fishy smell of the kibble
Probiotic Type
Live Probiotics
Best for: Owners of adult dogs with suspected chicken or poultry allergies who want a novel protein trial in a small bag.

Purina ONE31.1 lb Value
8.7OUT OF 10
Digestive Health8.5
Skin & Coat8.0
Ingredient Quality9.0
Owner Verdict9.0
This is the best value option for owners on a budget who still want probiotic support in their dog’s food. The 31.1 lb bag is the largest in this lineup, and it is designed specifically for adult dogs with sensitive stomachs. It uses high protein chicken as the base and includes probiotics for digestive support. Aggregate owner reviews rate it 4.6 out of 5 stars, with many owners noting that it helped firm up loose stools without breaking the bank.
The formula is made with natural ingredients, and it includes omega-6 fatty acids for skin health. The kibble size is standard, which works well for most medium to large breeds. Owners of multiple dogs especially appreciate the large bag size, as it reduces the frequency of repurchasing.
Flaws but not dealbreakers. This is a chicken based formula, so it is not suitable for dogs with poultry allergies. The ingredients are good but not as premium as the Pro Plan line, meaning it has slightly more fillers. Also, the bag is heavy and can be awkward to pour from without making a mess.
⚠Storage: The 31.1 lb bag is large. You will need a sturdy container with a lid to keep the kibble fresh and prevent pests.
Pros
- ✓Largest bag size at 31.1 lb offers best value per pound
- ✓Probiotics specifically for digestive support
- ✓High protein chicken formula for active dogs
- ✓Natural ingredients with added vitamins and minerals
Cons
- ✕Chicken is a common allergen, not for sensitive dogs
- ✕More fillers than the Pro Plan line
- ✕Large bag is heavy and awkward to pour
Best for: Budget conscious owners of adult dogs with mild digestive issues who need the lowest cost per meal from a large bag.
Purina Pro Plan Veterinary Supplements FortiFlora: Best Probiotic Supplement
#5
PurinaPowdered Supplement
9.0OUT OF 10
Digestive Health9.5
Immune Support9.0
Ease of Use9.0
Owner Verdict8.5
This is the best choice for dogs that need a targeted probiotic boost without changing their current food. FortiFlora is a powdered probiotic supplement that you sprinkle over your dog’s existing kibble. It is formulated by Purina’s veterinary nutritionists and is designed to support digestive health and immune function. It is also effective for managing occasional diarrhea. Aggregate owner reviews give it a strong 4.7 out of 5 stars, with many owners reporting that it resolved loose stools within a few days.
The powder comes in individual foil packets, which keeps the probiotics fresh and makes it easy to take on trips. Each packet is a single dose, so there is no measuring or guessing. The supplement is palatable, and most dogs eat it without noticing it is mixed into their food.
Flaws but not dealbreakers. This is a supplement, not a complete food, so you have to buy regular food separately. The cost per dose is higher than simply buying a food with probiotics already in it. Some owners also report that the powder can clump if the food is moist, so it is best to mix it into dry kibble immediately before serving.
⚠Storage: Keep the foil packets in a cool, dry place. Heat and humidity can degrade the live probiotics before you use them.
Pros
- ✓Individual foil packets keep probiotics fresh and potent
- ✓Can be used with any food, no need to switch diets
- ✓Effective for occasional diarrhea, per owner reviews
- ✓Veterinary formulated for immune and digestive support
Cons
- ✕Higher cost per dose than food with built-in probiotics
- ✕Must be mixed in immediately before feeding
- ✕Not a complete food, requires separate purchase of food
Probiotic Type
Live Probiotics
Best for: Owners who want to add a concentrated probiotic to their dog’s existing diet without switching to a new food.
Purina Pro Plan Complete Essentials Beef: Best Beef Option for Protein Variety

PurinaBeef First
8.5OUT OF 10
Digestive Health8.0
Skin & Coat8.0
Ingredient Quality9.0
Owner Verdict8.5
This is the best option for dogs that need a red meat protein source instead of poultry or fish. Real beef is the first ingredient, and the formula includes live probiotics for digestive health. It also features the Shredded Blend with crunchy kibble and tender pieces that many dogs find irresistible. The 5 lb bag is a convenient trial size for owners who want to rotate proteins or test if their dog tolerates beef well.
Beef is a rich source of amino acids and B vitamins, which support muscle development and energy levels. This makes it a good choice for active or working breeds. The kibble size is standard, and the bag has a resealable zipper for freshness.
Flaws but not dealbreakers. Beef is a more common allergen than salmon, so it is not the best first choice for dogs with known food sensitivities. The 5 lb bag is also not the most cost effective for large breeds. Some owners report that the beef formula has a stronger smell than the chicken or salmon versions.
⚠Allergies: Beef is one of the most common food allergens in dogs. Watch for signs of itching or digestive upset after switching.
Pros
- ✓Real beef is the first ingredient, great for protein variety
- ✓Shredded Blend texture appeals to picky eaters
- ✓Live probiotics support digestive health
- ✓5 lb bag is a good trial size for new proteins
Cons
- ✕Beef is a common allergen for many dogs
- ✕Small bag size is not cost effective for large breeds
- ✕Stronger smell compared to chicken or salmon formulas
Probiotic Type
Live Probiotics
Best for: Owners who want to rotate protein sources and try a beef based food with probiotics in a small trial bag.

9.0OUT OF 10
Digestive Health9.5
Skin & Coat9.3
Ingredient Quality9.0
Owner Verdict8.5
This is the same great sensitive formula as our top pick, but in a smaller 16 lb bag. It is the perfect middle ground for owners who want the salmon and rice formula with prebiotic fiber but do not need the full 30 lb bag. This size is ideal for small breed owners, multi dog households that want variety, or for anyone who wants to try the formula before committing to the larger size.
The formula includes real salmon as the first ingredient, prebiotic fiber for digestive health, and omega-6 fatty acids for skin and coat. It is easily digestible and free from artificial colors and flavors. The 16 lb bag is also easier to handle and store than the 30 lb version.
Flaws but not dealbreakers. The cost per pound is higher than the 30 lb bag, so if you know your dog does well on this food, the larger bag is a better value. The bag reseal is also basic, so you will want a storage container.
⚠Sizing: The 16 lb bag is more manageable for storage but still needs a sealed container to stay fresh in humid climates.
Pros
- ✓Same proven sensitive formula as the top pick
- ✓16 lb bag is easier to handle and store than 30 lb
- ✓Salmon is first ingredient, novel protein for allergies
- ✓Prebiotic fiber and omega-6 for gut and coat health
Cons
- ✕Higher cost per pound than the 30 lb bag
- ✕Kibble size may be too large for very small breeds
- ✕Bag reseal is basic, needs a storage container
Probiotic Type
Prebiotic Fiber
Best for: Owners who want to try the sensitive salmon formula without committing to the large 30 lb bag.
Buying Guide: Probiotics, Protein Sources, and Bag Size
Picking the right probiotic dog food comes down to three main factors. Understanding each one will help you match the food to your dog's specific needs.
What kind of probiotic support is in the food?
Not all probiotic foods work the same way. Some use prebiotic fiber, which feeds the good bacteria already in your dog's gut. Others add live probiotic cultures directly into the kibble.
The Purina Pro Plan Sensitive Skin & Stomach uses prebiotic fiber, while the Complete Essentials line adds live probiotics. Both approaches are effective, but live probiotics are more targeted for immediate digestive support. The Association of American Feed Control Officials (AAFCO) sets the nutritional standards for these foods, ensuring they are complete and balanced for adult dogs.
Which protein source is best for your dog?
The protein source matters a lot for dogs with food sensitivities. Chicken is the most common protein in dog food, but it is also the most common allergen. Salmon is a novel protein that is less likely to trigger a reaction.
Beef is another option, but it is also a known allergen for some dogs. If your dog has itchy skin or chronic ear infections, a food with a single novel protein source like salmon is often the best starting point. The Purina Pro Plan Complete Essentials Salmon is a great option for this scenario.
What bag size makes sense for your household?
Bag size affects both cost per meal and convenience. The 5 lb bags are perfect for trial runs or for small breed dogs that eat less. The 16 lb bag is a good middle ground for medium dogs.
The 30 lb and 31.1 lb bags offer the best value per pound, but they require storage space and a sealed container. If you have a large breed dog that eats 4 cups a day, the Purina ONE Plus Digestive Health 31.1 lb gives you the most meals per bag. Just be sure to transfer the kibble to an airtight bin to keep it fresh.
Who Should NOT Buy Best Dog Food with Probiotics
Probiotic dog food is not the right solution for every dog. Here are three types of buyers who should look at a different category instead.
You Need a Grain-Free Diet
If your dog has a confirmed grain allergy or you prefer a grain free diet, none of these Purina formulas will work. They all contain rice or other grains. A grain free diet may be necessary for dogs with specific sensitivities, but it is not recommended for all dogs due to concerns about heart health.
If you need grain free, look for a food that uses peas, lentils, or potatoes as carbohydrate sources instead of grains. You can also check out our guide to the best grain free dog food for a list of options.
Your Dog Needs a Prescription Diet
These foods are over the counter products designed for general digestive health. If your dog has a chronic condition like pancreatitis, inflammatory bowel disease, or severe food allergies, a prescription diet from your veterinarian is likely a better choice. Prescription diets are formulated to manage specific medical conditions and are not available without a vet's approval.
Do not try to manage a serious condition with an over the counter probiotic food.
You Want a Probiotic Supplement, Not a New Food
If your dog is already eating a food that works well, but you just want to add a probiotic boost, do not switch to a new food. Instead, use a probiotic supplement like the Purina FortiFlora that you can sprinkle on top of the current food. This gives you the benefits of probiotics without the risk of digestive upset from a food change.
It is also a good option for picky dogs that refuse to eat a new kibble.
Final Verdict
The Purina Pro Plan Sensitive Skin & Stomach Salmon Formula in the 30 lb bag is the best dog food with probiotics for most dogs. It combines a novel salmon protein with prebiotic fiber and omega-6 fatty acids, addressing both digestive issues and skin problems in one complete meal. It is the most versatile option for dogs with moderate to severe sensitivities.
If you want a more budget friendly option, the Purina ONE Plus Digestive Health gives you a large 31.1 lb bag with probiotics for digestive support at a lower cost per meal. Just be aware that it uses chicken, which is a common allergen. For dogs with poultry allergies, the Purina Pro Plan Complete Essentials Salmon is a great trial size to see if a novel protein helps.
Need a probiotic supplement instead of a new food? The Purina FortiFlora is a highly rated powdered probiotic that you can add to any meal. And if you are still unsure whether this category is right for you, scroll back up to the Who Should NOT Buy section before you make a purchase.
FAQ
What's the best dog food with probiotics overall?
The Purina Pro Plan Sensitive Skin & Stomach Salmon Formula in the 30 lb bag is the best overall. It uses real salmon as the first ingredient, prebiotic fiber for digestive health, and omega-6 fatty acids for skin and coat support. It is ideal for dogs with both digestive issues and skin sensitivities.
Can I give my dog probiotics every day?
Yes, you can give probiotics daily. The foods in this guide are designed for everyday feeding. For supplement powders like FortiFlora, follow the dosage instructions on the packaging.
Most dogs tolerate daily probiotics well, but consult your vet if you notice any changes in your dog's stool or behavior.
How long does it take for probiotics to work in dogs?
Many owners report seeing improvements in stool consistency within 3 to 7 days. For skin and coat benefits, it may take 2 to 4 weeks to notice visible changes. Consistency is key, so stick with the food for at least a full month before deciding if it works.
Are these foods safe for puppies?
No, these foods are formulated for adult dogs. Puppies have different nutritional needs, including higher protein and calcium levels for growth. If you have a puppy, look for a food specifically labeled for puppies.
You can check out our guide to the best puppy food for recommendations.
What is the difference between prebiotics and probiotics?
Prebiotics are a type of fiber that feeds the good bacteria already living in your dog's gut. Probiotics are live beneficial bacteria that are added directly to the food. The Purina Pro Plan Sensitive Skin & Stomach uses prebiotic fiber, while the Complete Essentials line uses live probiotics.
Both support digestive health, but they work through different mechanisms.
