Getting the diet right for a Maltese puppy is less about generic “puppy food” and more about matching their tiny mouths, fragile blood sugar levels, and notoriously sensitive digestion to a formula that won’t cause loose stools or picky refusals. The wrong kibble size alone can lead to gagging or skipped meals.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve spent countless hours cross-referencing ingredient panels, kibble dimensions, and feeding trial data so you don’t have to sift through hundreds of conflicting labels.
After analyzing the nutritional profiles of dozens of brands, this guide narrows the field to the five formulas that best meet the unique needs of a growing toy breed. This is your complete, no-fluff manual to finding the best dog food for maltese puppies.
How To Choose The Best Dog Food For Maltese Puppies
A Maltese puppy’s digestive tract is shorter and more sensitive than a large breed’s, and their energy requirements per pound of body weight are higher. The wrong formula can lead to hypoglycemia, loose stools, or refusal to eat. Here’s what to prioritize.
Kibble Size and Shape
A Maltese puppy has a tiny jaw and baby teeth that fall out between 4 and 6 months. Dry kibble must be small enough to pick up easily and porous enough to soften quickly. Look for kibble diameters under 10 millimeters — bags labeled “Small Breed” or “Toy Breed” are usually safe, but double-check the actual dimensions.
Protein and Fat Content
Maltese puppies need a minimum of 28% protein and 15-18% fat to sustain their fast metabolism without spiking insulin levels. High-quality animal protein should be the first ingredient, not a meat meal blend. Avoid formulas that rely on corn, wheat, or soy as protein fillers — these are harder for toy breeds to digest.
DHA and Calcium Balance
Docosahexaenoic acid (DHA) supports brain and eye development during the critical first year. Calcium and phosphorus must be precisely balanced — too much calcium can cause abnormal bone growth in a tiny breed. The ideal ratio is around 1.2:1 calcium to phosphorus. Any puppy food that lists calcium above 1.8% on a dry matter basis is too high for a Maltese.
Grain vs. Grain-Free
There is no blanket rule. Some Maltese puppies thrive on grain-inclusive formulas (brown rice, oatmeal) because the fiber stabilizes digestion. Others show signs of grain sensitivity — chronic ear infections, itchy skin. If you choose grain-free, ensure the formula uses lentils, peas, or sweet potatoes as carbohydrate sources rather than potato starch, which is nutritionally empty.

In‑Depth Reviews
1. Royal Canin Size Health Nutrition Small Puppy Dry Dog Food
Royal Canin designed this formula specifically for puppies 2 to 10 months with an expected adult weight between 9 and 22 pounds — which perfectly covers the Maltese growth curve. The crunchy kibble measures under 10 millimeters, making it easy for tiny mouths to pick up without gagging. Multiple reviewers with toy breeds like Chihuahuas and Bichons report zero diarrhea after switching, which is the strongest endorsement for a sensitive breed like the Maltese.
The recipe includes prebiotics and highly digestible proteins to support gut health, plus a specific antioxidant blend (vitamin E, vitamin C, taurine) targeted at immune development during vaccination schedules. The calcium and phosphorus levels are kept within the safe range for small breeds — approximately 1.0% calcium and 0.8% phosphorus, which avoids the skeletal over-acceleration that can cause leg deformities in toy puppies.
Several breeders specifically recommend this product to new owners, and the kibble pairs well with the brand’s canned thin slices in gravy for mixed feeding. Owners who switched from cheaper grain-inclusive brands noted firmer stools within 48 hours. The only minor complaint is that the bag does not have a resealable zipper, so you will want a storage container.
Why it’s great
- Kibble size is ideal for tiny puppy teeth
- Vet-recommended for digestive health
- Precise nutrient ratios for small breed growth
Good to know
- Contains chicken, so not suitable for chicken-allergic pups
- Bag lacks a resealable closure
2. Wellness CORE Small Breed Puppy Dry Dog Food, Turkey and Salmon Recipe
Wellness CORE Small Breed Puppy delivers a protein-dense profile with turkey and salmon as the main protein sources, hitting about 53% protein ingredients by weight. This high-protein approach supports lean muscle mass in a breed that tends to carry a fine bone structure. The kibble is small and rounds, which helps Maltese puppies who are still losing baby teeth to chew without discomfort.
The formula includes guaranteed levels of DHA sourced from salmon oil, which is critical for cognitive development in the first year. Calcium runs at roughly 1.2%, and phosphorus at 1.0%, staying safely below the upper limit for toy breeds. Several reviewers with sensitive-stomach pups noted that this food stopped constant hunger and produced well-formed stools, which is a common pain point for Maltese owners.
Customers reported healthy coat shine and fresh breath after a few weeks. One reviewer flagged that the bag lists turkey but contains chicken meal as well — check the ingredient list if your puppy has a confirmed chicken allergy. The 4-pound bag is a good starter size to test tolerance before committing to a larger bulk purchase.
Why it’s great
- High protein supports lean muscle in a toy breed
- Probiotics and antioxidants for immunity
- Small round kibble easy for tiny mouths
Good to know
- Contains chicken meal despite “Turkey” labeling
- Grain-free may not suit all puppies
3. Merrick Lil’ Plates Premium Grain Free Puppy Food For Small Dogs
Merrick Lil’ Plates uses real deboned chicken as the first ingredient, followed by sweet potatoes and peas for carbohydrate energy. The kibble is slightly larger than the Royal Canin option but still falls within the acceptable range for small breeds. The formula adds glucosamine and chondroitin — a proactive move for a breed prone to patellar luxation later in life.
The recipe includes omega-6 and omega-3 fatty acids to support the white coat and moist nose that a Maltese needs, plus probiotics to help regulate stool consistency. A few Shih Tzu and picky-eater owners reported that their puppies scarf this down eagerly after refusing other grain-free brands. One reviewer noted a strong, pleasant smell compared to other “premium” foods, which is a minor but real factor when your puppy’s meal is waiting in the bowl.
On the downside, the 4-pound bag price sits at the upper end of the mid-range tier, and some owners found that their puppies began to refuse it after finishing the first bag — suggesting the taste may not hold long-term appeal for every Maltese. The grain-free formula works well if your puppy shows grain sensitivity, but it is not the cheapest option to maintain if you have a heavy eater.
Why it’s great
- Real deboned chicken first ingredient
- Joint support from glucosamine and chondroitin
- Omega fatty acids for white coat shine
Good to know
- Some picky eaters lose interest after one bag
- Higher per-pound cost than mid-range options
4. Hill’s Science Diet Puppy Dry Dog Food, Lamb Meal & Brown Rice
Hill’s Science Diet Puppy in Lamb Meal and Brown Rice is formulated with balanced minerals for bone growth and DHA from fish oil for brain and eye development. The lamb-based protein makes this an excellent choice for Maltese puppies who show sensitivity to chicken or turkey. The kibble size is moderate — not the smallest on this list, but Maltipoo owners report their dogs manage it without issues.
This formula uses brown rice as a whole-grain carbohydrate source, which provides steady energy release and gentle fiber that many toy breed owners find helps stabilize blood sugar during the high-energy puppy months. The veterinarian-recommended reputation carries weight here: if your vet is involved in your puppy’s early health plan, they are likely to approve this specific line.
Several customers mention that their picky puppies accepted this food without a transition period, which is rare for a lamb-based formula — many lamb recipes have a stronger smell that can deter young dogs. Stool quality was noted as consistently firm. The bag is standard size with no zipper, so plan to transfer to an airtight container for freshness.
Why it’s great
- Lamb protein avoids common chicken allergens
- Brown rice provides gentle, steady energy
- Vet-recommended and trusted for sensitive systems
Good to know
- Kibble slightly larger than specialty small-breed options
- Not grain-free if that is your preference
5. Bil-Jac Small Breed Puppy Dry Dog Food, Chicken Oatmeal & Yam Recipe
Bil-Jac Small Breed Puppy stands out for its proprietary soft, porous kibble shape that is noticeably easier for teething puppies to pick up and chew than standard crunchy pellets. The formula uses oatmeal and yams as gentle fiber sources, which helps soothe the sensitive stomachs that Maltese puppies are known for during the weaning-to-solid transition.
This recipe uses 5 pounds of fresh chicken per 6-pound bag, providing a high-quality animal protein base. The protein and fat levels are optimized for the rapid development and high energy needs of small breeds without causing digestive stress. Vitamin C and E are added specifically to bolster the developing immune system during the vulnerable first year, when Maltese puppies often have their first rounds of vaccinations and parasite prevention.
Some owners of picky eaters report that their dogs devour this food immediately. However, one detailed review noted that their dog needed nearly twice the recommended daily amount to feel full, and the resulting stool was foul-smelling with undigested kibble visible — suggesting the formula may not be fully digestible for all individuals. Start with a small bag and monitor your puppy’s stool consistency closely.
Why it’s great
- Soft porous shape ideal for teething mouths
- Gentle oatmeal and yam fiber for sensitive stomachs
- Picky eaters tend to love the taste
Good to know
- Some pups need more food to feel satisfied
- Can produce foul-smelling stools in sensitive dogs
