Our Picks at a Glance


How To Choose The Best Dog Food For Yorkie Poo Puppy
Yorkie Poos are a cross between a Yorkshire Terrier and a Toy or Miniature Poodle, which means they generally stay under 15 pounds as adults. Their rapid growth phase (2–10 months) demands a puppy formula with controlled calcium for bone development and DHA for brain development. You also want a small kibble shape — a Yorkie Poo’s mouth is tiny, and oversized chunks get ignored or gulped down whole.
Kibble Size and Shape
Look for a bag labeled “small breed” or “extra small breed.” The kibble should be under about 10 millimeters in diameter — small enough for your puppy to pick up easily and chew without choking. Some brands make a porous, soft-textured bite that is easier on teething gums.
Guaranteed Analysis: Protein and Fat
Small breed puppies have a higher metabolic rate than large breeds. Look for a crude protein minimum around 28–32% and crude fat around 15–20% on a dry matter basis. Those levels support their energy needs without overloading their small digestive system.
Digestive Support
Yorkie Poos can have sensitive stomachs. Prebiotics (like chicory root) and probiotics (live active cultures) help maintain regular, firm stools. A single-ingredient novel protein like turkey or lamb can also reduce the chance of food sensitivities.

In‑Depth Reviews
1. Royal Canin Size Health Nutrition Small Puppy Dry Dog Food, 14 lb Bag
Our pick — over 4.5★ from 12,500+ verified ratings; the strongest balance of quality and price.
Crunchy kibble the size of a pea that Yorkie Poo mouths actually want to chew.
This formula is designed for puppies 2 to 10 months old with an expected adult weight of 9 to 22 lbs, which covers most Yorkie Poos (though the smaller ones may fit the X-Small version better). Buyers report the food smelled fresh when they opened the bag and their puppies digested it well, with one owner calling it “pretty worth it for the money.” The 14 lb bag gives you the longest run between refills of any option here, saving you trips to the store.
Antioxidants support the developing immune system, while prebiotics and protein promote healthy gut bacteria. The crunchy kibble also helps scrape away plaque as your puppy chews, which is a bonus for a breed prone to dental issues. Unlike the Bil-Jac below which has a softer texture, Royal Canin’s kibble holds its crunch even when left in the bowl for a few hours.
This is the food a breeder or vet is likely to recommend because it covers the basics — brain development, energy needs, digestive health — without any filler. The 14-pound bag turns the per-meal cost into a solid mid-range value even though the upfront price is higher than most.
Why It Works for Yorkie Poos
- Crunchy kibble scrubs teeth and satisfies natural chewing instinct
- 14 lb bag lasts a small puppy well over a month
- Prebiotics help keep stool firm and consistent
Watch For
- Kibble may be too large for a 4-week-old puppy just weaning
- Chicken base can trigger sensitivities in some toy breeds
Your pick if: You want a widely trusted, vet-recommended formula that balances growth support with digestive health in one big bag.
Reconsider if: Your Yorkie Poo is under 3 pounds at 8 weeks old — you may need the X-Small kibble below.
2. Royal Canin Size Health Nutrition X-Small Puppy Dry Dog Food, 3 lb Bag
The one that fits inside a teething Yorkie Poo’s mouth without any struggle.
This is the same trusted Royal Canin recipe but with a smaller kibble dimension specifically for puppies expected to weigh no more than 8 lbs as adults. A Yorkie Poo on the toy end of the spectrum (often under 6 lbs) will find these tiny pieces easier to pick up and chew. One reviewer with a Yorkie confirmed, “My Yorkie was eating this food when she was a baby,” and another noted the kibble softens quickly when soaked for sensitive teeth. The 3 lb bag is small, but the trade-off is you get the ultra-small pellet you cannot find in the standard Small Breed bag.
It shares the same prebiotic and antioxidant profile as its larger-bag sibling, so your puppy gets the same immune and digestive support. The crunchy texture still provides dental benefits, but the pieces are small enough that a 5-week-old puppy just coming off milk can handle them. Unlike the Merrick option that uses sweet potato as a binder, this formula relies on rice and brewers rice, giving it a simpler carbohydrate source that is easier on sensitive stomachs.
For owners of extra-small Yorkie Poos, this 3 lb bag is the top performer because the kibble size eliminates the “I cannot chew this” tantrum that many toy breed puppies throw with larger kibble. You pay a bit more per pound than the 14 lb bag, but you get the correct geometry for your puppy’s mouth.
Kibble Geometry Win: The tiny pellet is designed for mouths under 8 lbs adult weight, making it the most physically accessible option for toy Yorkie Poos.
Bag Size Reality: At 3 lb, you will reorder roughly twice as often as you would with the 14 lb Small Breed bag.
3. NutriSource Small & Medium Breed Puppy Dry Dog Food, 12 lb
A grain-inclusive powerhouse that sends digestion and coat quality in the right direction.
NutriSource brings probiotics and prebiotics alongside balanced Omega-3 and Omega-6 fatty acids with DHA — three things a Yorkie Poo puppy needs for brain development, a shiny coat, and regular stool. The formula is grain-inclusive (brown rice, oatmeal) rather than grain-free, which can actually be easier on a puppy’s digestive system because grains provide soluble fiber that firms up stool. Owners mention their puppies have “zero digestive issues” and “excellent digestion” on this food. The 12 lb bag is a smart mid-range purchase: you get the largest volume of a premium formula without paying the premium-per-pound of the smaller bags.
The kibble shape is round, about the size of a pencil eraser, which makes it easy for Yorkie Poos to pick up without gagging. L-Carnitine and taurine support heart health, which is important because small breeds can be prone to dental disease that affects the heart. Unlike the Wellness CORE that is grain-free and higher in protein (53% protein ingredients vs. NutriSource’s more moderate levels), this recipe is less likely to send a sensitive puppy’s stomach into overdrive.
If your breeder sent your puppy home on NutriSource, the 12 lb bag saves you from buying the smaller 4 lb bag repeatedly. Reviews note that the kibble is hard — a few buyers add water to soften it for teething puppies.
Stands Out For
- Probiotics + prebiotics shown to produce firm, odor-free stool
- Omega fatty acids promote a silky coat that vets notice
- 12 lb bag delivers strong value for a premium recipe
Consider This
- Round kibble is harder than Bil-Jac’s porous bites — may need soaking for teething puppies under 4 months
- Grain-inclusive recipe means higher carbohydrate content than grain-free alternatives
Solid pick for: Owners who want a proven, breeder-recommended formula with excellent digestive and coat results in a large bag.
Skip if: Your Yorkie Poo has a confirmed grain allergy — then go with the Wellness CORE or Merrick below.
4. Wellness CORE Small Breed Puppy Dry Dog Food, Grain Free, 4 lb
Turkey and salmon in every bite — a single-novel-protein dream for pups with chicken sensitivity.
This grain-free formula uses turkey and salmon as the primary protein sources instead of chicken, making it a strong pick if your Yorkie Poo has shown signs of chicken intolerance (scratching, loose stool, ear redness). The guaranteed analysis shows 53% of the ingredients come from high-quality protein, which supports lean muscle development without unnecessary fillers. DHA supports brain development, and calcium and phosphorus work together for healthy bone growth. The kibble size is small — appropriate for a toy breed — but it is a denser, crunchier piece than the Bil-Jac option.
Wellness CORE is made in the USA with no corn, wheat, soy, or artificial preservatives. The 4 lb bag is a practical starter size; if your puppy likes it, you can move up to a larger bag. The main trade-off is that a grain-free diet is higher in protein and fat, which can sometimes cause faster weight gain if you over-feed. Compared to the Merrick Lil’ Plates below, this formula is slightly higher in protein and lower in carbohydrates.
For a Yorkie Poo with a sensitive stomach that cannot handle chicken or grains, this turkey-and-salmon recipe is the cleanest slate to start with. The single-bag price is mid-range, but the grain-free premium means you pay a bit more per pound than the Bil-Jac or the NutriSource grain-inclusive options.
Protein Switch Benefit: Turkey and salmon offer a different amino acid profile than chicken, reducing the chance of a food allergy developing.
One Limitation: The 4 lb bag runs out fast; expect to reorder every 2–3 weeks for a single puppy.
5. Merrick Lil’ Plates Premium Grain Free Dry Puppy Food, 4 lb
Real deboned chicken plus sweet potato — a grain-free duo that tiny stomachs tolerate well.
Merrick’s Lil’ Plates line is formulated specifically for small breed puppies, with a smaller kibble dimension that Yorkie Poo mouths can handle. Deboned chicken is the first ingredient, providing high-quality protein for muscle development. What sets this apart from the other grain-free options is the addition of glucosamine and chondroitin — two compounds that support healthy hip and joint development, which is especially important for a fast-growing toy breed that will live 12–15 years. Customers note that two 4-month-old puppies love this food and have “better stool quality” compared to a previous premium brand. The kibble also helps clean teeth and freshen breath as the puppy chews.
Omega-6 and Omega-3 fatty acids nourish the skin and coat, which helps prevent the dry flaky skin that some Yorkie Poos develop. The 4 lb bag is priced in the same mid-range zone as the Wellness CORE, but Merrick includes joint supplements that the CORE formula does not. The one trade-off is that a few owners mention the price — around for a 4 lb bag — is higher than some grain-inclusive alternatives, but they acknowledge the ingredients justify it.
If you want a grain-free food that also protects your puppy’s developing joints and coat, Merrick Lil’ Plates delivers both with a single bag. It is a better value than buying separate joint supplements.
Built-in Extras
- Glucosamine and chondroitin for hip and joint support
- Probiotics aid digestion — reviewers point out less diarrhea after switching
- Small-sized kibble doubles as a dental scrub
Cost Factor
- At ~ per pound, it is one of the pricier options per feeding
- Some puppies find the chicken-sweet potato combo too rich; transition slowly
Choose this if: Joint health and coat condition are priorities — the glucosamine and omega fatty acids make it a two-in-one formula.
Look elsewhere if: You need a very high-protein, low-carb recipe — the sweet potato adds digestible carbs that reduce the protein percentage slightly.
6. Bil-Jac Small Breed Puppy Dry Dog Food, Chicken | Oatmeal & Yam Recipe, 6 lb
Porous, soft bites that turn into mush with a splash of warm water — perfect for weaning.
Bil-Jac’s proprietary shape is soft and porous, meaning your Yorkie Poo puppy can chew it without any pain, even while teething. The recipe uses oatmeal and yams — gentle fiber sources — to soothe sensitive stomachs and boost nutrient absorption. The 6 lb bag uses 5 lbs of fresh, real chicken to produce the kibble, giving it a high meat content. Shoppers say that dogs go “frantic” for it, though one owner warned that 2X the recommended daily amount caused constipation; following the feeding guide avoids that issue. The soft texture makes it ideal for the transition from weaning to solid food — unlike the crunchy Royal Canin kibble that stays hard, Bil-Jac’s bites soften quickly.
At 6 lb, this is one of the best budget-friendly options that still uses real chicken as the primary ingredient. It is fortified with Smart Defense Vitamin C and E to support the immune system during the first year. The one honest catch: the soft texture means the kibble does not provide dental scrubbing like a crunchy kibble would, so you may need to incorporate dental chews or brushing later.
For a 6-week-old Yorkie Poo just leaving its mother, Bil-Jac is the gentlest option to start with. The texture reduces the risk of choking or gum injury that can happen with harder kibble.
Texture Advantage: The soft, porous bites absorb water in under a minute, becoming a porridge-like consistency that tiny mouths manage easily.
Feeding Precision: Stick to the bag’s recommended amount — too much can lead to loose stool and undigested kibble.
7. NutriSource Puppy Food for Small and Medium Breeds, Chicken Meal and Rice, 4LB
The food many breeders send home with new pups — and for good reason.
This is the smaller 4 lb bag version of the NutriSource recipe, making it a perfect trial size before committing to the 12 lb bag. It is formulated for breeds that mature at less than 50 pounds, which covers all Yorkie Poos. The balanced Omega-3 and Omega-6 fatty acids with DHA support brain development, while the probiotics and prebiotics promote gut health. Buyers report their puppies have “excellent digestion, soft coat, healthy skin” and “firm and pretty much odor free” stools. One reviewer noted that a picky dog stopped liking it after a while, which can happen with any food — the majority of feedback is positive.
The kibble is small and easy to eat, though some teething puppies needed water added to soften it. The chicken meal and rice formula is grain-inclusive, which provides steady energy without the protein spike of a grain-free recipe. Compared to the Bil-Jac soft bites, this kibble is crunchier and provides more dental scraping action, but it is harder on a 3-month-old puppy’s teeth.
If your Yorkie Poo came home on NutriSource, stick with it — the 4 lb bag is the easiest way to continue without waste. It is a solid entry-level premium option that keeps your puppy’s digestion regular and coat shiny.
Breeder Trust
- Commonly recommended by breeders for consistent, predictable results
- Small kibble size fits Yorkie Poo mouths
- Probiotics lead to firm, low-odor stool — helpful for house training
Teething Note
- Harder kibble may need soaking for puppies under 4 months
- Chicken meal base is a single protein, but some dogs develop a preference issue over time
Start here if: Your breeder already uses NutriSource — consistency prevents digestive upset during the first week home.
Switch if: Your puppy shows signs of chicken sensitivity (itchy paws, ear infections) — then go with the turkey-based Wellness CORE.
Understanding the Specs
DHA — Brain and Eye Development
Docosahexaenoic acid (DHA) is an omega-3 fatty acid found naturally in fish oil and certain animal tissues. It supports the development of your Yorkie Poo’s brain, central nervous system, and retina. Look for DHA listed in the guaranteed analysis or in the ingredient list as fish oil or salmon oil. Puppies that get adequate DHA during the first 10 months tend to learn commands and house-training routines faster.
Probiotics and Prebiotics — Digestive Regularity
Probiotics are live beneficial bacteria that colonize the gut and help break down food. Prebiotics (like chicory root or inulin) are fibers that feed those bacteria. Together they create a stable gut environment, which reduces diarrhea, gas, and constipation. For a Yorkie Poo with a sensitive stomach, a food with both probiotics and prebiotics can mean the difference between a firm stool and a messy cleanup.
