Those reddish-brown streaks under a Maltese’s eyes aren’t just a cosmetic issue—they’re often a direct signal that your dog’s food is triggering a reaction. Tear staining in this breed is notoriously linked to diet, specifically to ingredients that cause mineral imbalances, allergies, or poor digestion. Choosing the right food is the single most effective intervention you can make, and it starts with understanding which proteins, grains, and additives are driving the problem.
I’m Mo Mahin — the founder and writer behind Furric. Over the past decade, I’ve analyzed thousands of pet food formulations, cross-referencing ingredient profiles with owner-reported outcomes, to understand precisely how nutritional biochemistry affects breed-specific issues like tear staining in white-coated dogs.
After evaluating dozens of options, I’ve narrowed the field down to the top contenders that target the root causes. This guide breaks down the best dog food to prevent tear staining in maltese, focusing on clean proteins, limited ingredients, and skin-and-coat-supporting fatty acids.
How To Choose The Best Dog Food To Prevent Tear Staining In Maltese
Not all dog foods affect tear staining equally. Maltese have a unique combination of a white coat, a brachycephalic facial structure, and a predisposition to food sensitivities. The right formula must address all three—otherwise, you’re just managing symptoms instead of solving the root issue.
Protein Source and Allergen Profile
The most common dietary trigger for tear stains is a protein allergy, often to chicken or beef, which causes inflammation and excessive tear production. A novel protein like salmon, whitefish, or turkey often eliminates this trigger. Formulas labeled “Limited Ingredient” or featuring a single protein source are your safest bet for isolating and removing the irritant.
Kibble Size and Jaw Mechanics
Maltese have small mouths and delicate jaws. A kibble that is too large forces them to chew awkwardly, which can disrupt normal swallowing and increase tear production from physical strain. Look for kibble specifically cut for toy or small breeds—typically 7 to 10 mm in diameter—to ensure easy eating and reduced facial pressure.
Omega-3 and Omega-6 Fatty Acid Balance
Fatty acids are the cornerstone of skin and tear-duct health. Omega-3s (EPA/DHA) reduce systemic inflammation, which calms tear-duct irritation and limits the iron-rich porphyrin that stains white fur. Salmon oil, herring oil, and green-lipped mussel are premium sources. Aim for a food that lists a named fish oil or seed oil high on the ingredient panel.
Probiotics and Digestive Support
A healthy gut microbiome is directly linked to reduced ocular discharge. Probiotics, prebiotics (like chicory root or dried fermentation products), and easily digestible fibers help your Maltese absorb nutrients more efficiently and excrete fewer inflammatory metabolites. Foods that include species-specific probiotics offer an edge for stain-prone individuals.

In‑Depth Reviews
1. Blue Buffalo True Solutions Skin & Coat Care Wet Dog Food
This is a true category leader for tear staining because it directly attacks two root causes: food sensitivities and poor skin health. The #1 ingredient is real whitefish—a novel, easily digestible protein that rarely triggers the allergic porphyrin cascade in Maltese. The formula explicitly excludes dairy and eggs, two of the most common hidden allergens that produce those reddish-brown streaks under the eyes.
The Omega 3 and 6 fatty acid profile in this wet food is substantial enough to make a visible difference in fur brightness and tear-duct inflammation relief within a few weeks. Many owners report a complete cessation of scratching and eye discharge after switching exclusively to this recipe. The canned format also provides added hydration, which dilutes tear pigment concentration in the fur.
It’s a wet-food-only approach, so if your Maltese prefers dry kibble, you can mix this in as a topper. The 12-count case at 12.5 ounces per can is substantial. Just note that this is formulated for all breed sizes, so portion control is essential for a 5- to 10-pound Maltese. Owners consistently report that even finicky dogs devour this whitefish recipe eagerly.
Why we love it
- Novel whitefish protein minimizes allergic tear triggers
- Explicitly free of dairy, eggs, corn, wheat, and soy
- High Omega-3 content visibly reduces fur staining
Good to know
- Wet food only—requires refrigeration after opening
- Moderate price per case compared to dry alternatives
2. ORIJEN Amazing Grains High Protein Small Breed Recipe
ORIJEN’s Small Breed recipe uses a WholePrey ratio—meaning meat, organs, and cartilage—to deliver a nutrient profile that mimics what a small dog would eat in the wild. This biological appropriateness reduces the inflammatory load that often manifests as ocular staining. The inclusion of poultry and fish with both Omega-3 and Omega-6 fatty acids supports tear-duct lining health directly.
At 9 mm x 5 mm, the kibble shape is ideal for Maltese jaws, reducing chewing strain that can trigger excess tearing. The formula is corn-free, wheat-free, soy-free, and potato-free, which eliminates many common starch-based triggers. Owner reviews specifically note that this food “doesn’t cause eye gunk”—a direct signal that porphyrin production is under control. The prebiotic and probiotic blend further aids digestive efficiency.
It is a premium-priced kibble, but one bag lasts roughly six weeks for a small Maltese, especially if supplemented with cooked food. A small subset of sensitive dogs may still react to the poultry content, so monitor closely during the first week of transition. For owners who want a biologically appropriate, high-protein kibble, this is the gold standard for tear-stain prevention.
Why we love it
- WholePrey ratio reduces systemic inflammation
- Small kibble shape designed for toy breeds
- Clean ingredients with proven stain-free results
Good to know
- Contains poultry protein (potential allergen for some)
- Higher cost per pound than mid-range options
3. Open Farm Grain-Free Dry Dog Food for Small Breeds
Open Farm combines a dual poultry protein source (chicken and turkey) with green-lipped mussel—a potent source of Omega-3 fatty acids and chondroitin that directly reduces inflammation. For tear staining, the inclusion of green-lipped mussel is a standout feature because it provides a concentrated anti-inflammatory effect that calms the tear ducts without needing artificial additives.
This kibble is grain-free and packed with non-GMO superfoods like sweet potato and pumpkin, which provide gentle fiber that supports consistent digestion. A healthy gut means fewer endotoxins that can trigger eye discharge. The kibble is explicitly cut smaller for small breeds, helping Maltese chew without excessive facial pressure. Traceable ingredients allow you to verify every component if your dog is extremely sensitive.
The four-pound bag is ideal for testing the formula before committing to a larger size. Some owners report that the poultry blend still triggers mild staining if their Maltese has a specific chicken sensitivity—if that’s the case, consider a single-novel-protein formula instead. For most Maltese, the high protein and functional ingredients make this a solid mid-range pick with excellent stain-control potential.
Why we love it
- Green-lipped mussel provides natural anti-inflammatory support
- 100% traceable, ethically sourced ingredients
- Small kibble cut for easy chewing
Good to know
- Contains poultry (chicken and turkey) as main proteins
- Grain-free may not suit all digestive systems
4. Health Extension Little Bites Dry Dog Food for Toy and Small Breeds
Health Extension packs over 30 superfoods into this single formula, including turmeric, apple cider vinegar, coconut oil, blueberries, and cranberries. Turmeric is particularly relevant for tear stains because of its systemic anti-inflammatory properties—it reduces the oxidative stress that turns tear porphyrin dark. The added probiotics and prebiotics fortify the gut microbiome, which is a foundational factor in preventing ocular discharge.
This formula uses real deboned chicken as the first ingredient, providing high-quality lean protein for small breeds. The kibble is designed for teacup and toy breeds, so the size and shape require minimal chewing effort for a Maltese. It is also free of corn, wheat, soy, artificial flavors, colors, and preservatives—eliminating many common dietary irritants. The all-life-stages formulation means it works for puppies through seniors.
The primary consideration is that chicken is the main protein, and chicken is one of the most common allergens in white-coated breeds. If your Maltese has a known chicken sensitivity, this formula may not resolve staining fully. For owners whose dogs tolerate chicken well, the superfood support makes this a strong stain-preventive choice at a reasonable per-pound cost.
Why we love it
- Turmeric and superfoods target inflammation directly
- Probiotics and prebiotics support gut health
- Specifically designed for toy and teacup breed jaws
Good to know
- Chicken-based protein (potential allergen trigger)
- All-life-stage formula may need portion adjustment for adults
5. Royal Canin Size Health Nutrition Small Adult Dry Dog Food
Royal Canin Small Adult is engineered specifically for dogs weighing 9 to 22 pounds. Its precise calcium and phosphorus ratio supports strong jaw and bone structure—crucial for a breed whose small facial bones can contribute to tear-duct misalignment. While this formula doesn’t market itself as a stain-fighter, the highly digestible proteins and precise fiber blend reduce overall digestive inflammation that often manifests as eye discharge.
The kibble texture is designed to be crunchy but easy to break, encouraging chewing mechanics that naturally express tear ducts without clogging. The formula includes prebiotics and a tailored microbiome support system. For Maltese owners who prefer a veterinarian-backed brand with decades of research, this offers a safe, predictable baseline that often reduces staining through improved overall metabolic efficiency.
The clear limitation is its chicken-based protein—chicken is a common stain trigger. If your Maltese has reacted to chicken before, this is not the right choice. Additionally, the four-pound bag is smaller than some competitors, so long-term use may require frequent repurchasing. For owners without chicken sensitivities, this is a reliable, science-backed option that supports physical structure and digestive harmony.
Why we love it
- Precise calcium/phosphorus ratio supports jaw health
- Highly digestible proteins reduce metabolic inflammation
- Veterinary-backed formulation with predictable results
Good to know
- Chicken-based protein may trigger tear stains in sensitive dogs
- Small bag size for the price point
6. Stella & Chewy’s Lil Bites Savory Stews Beef & Chicken Dinner
Stella & Chewy’s Lil’ Bites Stews bring a limited-ingredient wet option with turmeric specifically added for anti-inflammatory support. The turmeric content is a smart inclusion for tear staining because it directly reduces the oxidation pathway that makes porphyrin stains darken on white fur. The stew format provides high moisture content, which dilutes tear pigment concentration and flushes the system naturally.
This formula is free of grains, legumes, potatoes, carrageenan, and artificial additives—a short ingredient list that reduces the chance of hidden triggers. It includes salmon oil and sunflower oil for Omega fatty acids, supporting skin and coat health which indirectly reduces eye irritation. The 2.7-ounce recyclable cups are pantry-friendly and require no refrigeration until opened, making portion control for a Maltese straightforward.
The beef and chicken combination means two potential allergens in one product. For Maltese with known red meat or poultry sensitivities, this dual-protein approach may still cause issues. The total package price for 12 cups is entry-level, but the per-serving cost is higher than dry kibble. This works best as a rotational or topper option for stain-prone dogs.
Why we love it
- Added turmeric actively reduces stain oxidation
- High moisture content dilutes porphyrin concentration
- Limited ingredient list with no grains or carrageenan
Good to know
- Contains both beef and chicken (multiple allergens)
- Higher cost per serving than dry kibble
7. Diamond Naturals Skin & Coat Real Salmon and Potato Recipe
Diamond Naturals Skin & Coat delivers a salmon-based, potato-anchored formula that is one of the most budget-conscious ways to address tear staining through diet. Salmon is a novel protein for most Maltese, and the inclusion of K9 Strain proprietary probiotics supports digestive health—which directly reduces the systemic inflammation that drives tear production. Owners with allergy-prone dogs frequently report that this food clears up skin issues and itching within weeks.
This recipe is fortified with Omega fatty acids from salmon oil, providing the skin-and-coat benefits that help maintain a clear, white facial coat. The 30-pound bag size is a major value advantage compared to smaller specialty bags, making it feasible for multi-dog households or long-term feeding. It is made in the USA and is free of artificial colors and corn (though it does contain grains).
The most important caveat for a Maltese owner is the kibble size: this is a medium-breed kibble, not a small-breed formula. The larger pieces may require extra chewing effort that can physically stress the tear ducts. For a toy Maltese under 7 pounds, you may need to moisten the kibble or crush it slightly. Also, the potato content is moderate—some sensitive dogs may not tolerate nightshade-based carbohydrates well. For the price, the stain-control potential is excellent.
Why we love it
- Novel salmon protein avoids common poultry triggers
- K9 Strain probiotics support gut health
- Exceptional per-pound value in a 30lb bag
Good to know
- Medium-breed kibble size may be too large for Maltese
- Contains grains and potato (potential minimal irritants)
