Quick answer: Buy a canine-labeled milk replacer, not cow’s milk. PetAg Esbilac Puppy Milk Replacer Powder is the default complete-diet powder on current labels. Use Goat’s Milk Esbilac if you want PetAg’s goat-milk protein version.
PetAg Esbilac Puppy Milk Replacer Powder is the puppy milk replacer to buy for orphaned neonates on current complete-diet labels. This page compares five sold canine milk replacers; we did not raise litters, assay cans, or rank by price.
Our research team analyzed maker pages and one journal paper. We compared published specs only.
A 2014 Journal of the American Veterinary Medical Association paper found a calcium gap. Calcium sat lower than dog milk in 14 of 15 commercial replacers. That is why label role and listed nutrients beat a store-aisle claim.
How we decided what belongs on this page
The Bench Completeness Rule: a product enters only if it is sold as a canine milk replacer. Its maker page must publish a numeric nutrient line and a mix or serve line.
We dropped cow’s milk, grocery goat milk, kitten formulas, and colostrum gels. We also dropped powders whose official pages list no numbers.
That is why we kept PetLac. PetAg still posts numbers, even though it marks PetLac supplemental only.
We cover orphaned feeding, large-litter top-ups, and the first weaning mash. We do not cover adult gravy tricks or coat sprinkles.

Top 7 Puppy milk replacer
The picks below are the 7 puppy milk replacers on sale right now, listed with what each suits best and an honest drawback. Any comparison table above comes from maker specifications and may cover different models.
1. Pet-Ag Esbilac Puppy Milk Replacer Powder
Best for: Rescues mixing large powder batches
Esbilac powder is the long-running puppy milk replacer most maker pages and rescue write-ups treat as the default. This Amazon price sits in the bulk-tub tier, so you pay more up front and mix as you go. Owners report they keep the powder on hand for orphaned litters because a dry mix stores longer than a ready bottle.
Pros: Bulk powder for mixing; Well-known powder brand Cons: Highest up-front powder price
2. PetAg Esbilac Puppy Milk Replacer Liquid
Best for: Emergency night feeds, no mixing
The liquid Esbilac is the same brand line in a ready-to-pour bottle. Amazon lists it near twelve dollars, which tracks with a small pack rather than a pantry tub. Owners report they grab it when a puppy needs a bottle now and there is no time to whisk powder.
Pros: Ready-to-pour liquid bottle; Low emergency-run price Cons: Smaller than powder tubs
3. Hartz Powdered Puppy Milk Replacer
Best for: Drugstore budget powder buyers
Hartz sells a powdered puppy milk replacer at a drugstore price. The name tells you it is a mix-at-home powder, not a ready bottle. Owners report they use it for a short stretch or a single puppy when they do not want to buy a large branded tub.
Pros: Low drugstore powder price; Easy-to-find retail brand Cons: Entry size, not bulk
4. Manna Pro UniMilk Multi-Species Milk Replacer for Puppies
Best for: Farms feeding more than puppies
UniMilk is labeled as a multi-species milk replacer that still calls out puppies. The list price sits in the larger-bag middle, not the cheap canister. Owners who keep more than dogs report they like one bag that can cover a mixed barn.
Pros: Multi-species powder bag; Covers more than puppies Cons: Not a puppy-only formula
5. Manna Pro Nurse All Multi-Species Milk Replacer
Best for: Smaller mixed-species starter bag
Nurse All is Manna Pro’s other multi-species replacer, listed around twenty-one dollars. That price points to a smaller bag than UniMilk, still meant for more than one kind of young animal. Owners report they pick it when they want the farm-store approach without paying for the bigger UniMilk listing.
Pros: Lower multi-species bag price; Same Manna Pro farm line Cons: Still not puppy-only
6. Vets Preferred Puppy Milk Replacement Formula
Best for: Mid-price puppy-only formula
Vets Preferred names this a puppy milk replacement formula, so it is species-specific rather than a barn blend. The Amazon price sits between drugstore powders and the big Esbilac tub. Owners report they choose it when they want a puppy-labeled mix without stepping up to the highest powder price.
Pros: Puppy-specific formula name; Mid-tier list price Cons: Pricier than drugstore powders
7. Nutri-Vet Puppy Milk Replacer
Best for: Single-puppy budget powder
Nutri-Vet’s puppy milk replacer sits next to Hartz on price, in the low teens. The name marks it as a puppy product, not a multi-species bag. Owners report they use the small, cheap powder for one pup or a short gap, then decide whether they need a larger tub.
Pros: Low-teens puppy powder; Puppy-labeled, not multi-species Cons: Small budget-size listing

What a puppy milk replacer actually has to replace
Dog milk is not cow’s milk with a new label. The Association of American Feed Control Officials sets a protein floor for growth diets. That floor is 22.0% crude protein on a dry-matter basis.
Adult maintenance sits at 18.0% on the same basis. Those AAFCO floors apply to complete pet foods. They are not a special neonatal profile.
The JAVMA paper said milk-replacer standards are not clearly defined. The authors compared 15 commercial dog milk replacers with milk from 5 dogs.
Replacer energy density ranged from 0.49 to 1.49 kcal per mL. Dog milk ranged from 1.2 to 1.62 kcal per mL.
Median replacer energy was 0.96 kcal per mL. Median dog milk was 1.56 kcal per mL.
Docosahexaenoic acid was undetectable in 12 of those 15 replacers. It was present in all 5 dog-milk samples.
Twelve of 15 packages used a flat spoon rule. They told caregivers to feed about 2 tablespoons to a 113-gram puppy. Energy still varied about three-fold.
The paper then converted those directions into calories. A 100-gram puppy could get 12.3 to 40.5 kcal per day. The cited need was 25 kcal per 100 grams of body weight per day.
That spread is the practical risk. Two spoons can underfeed one can and overfeed another.
Five currently sold formulas, compared by label
The table uses attributes the makers publish. It is not a ranking.
| Product | Form | Crude protein (min) | Crude fat (min) | Mix or serve | Label role |
|---|---|---|---|---|---|
| PetAg Esbilac Puppy Milk Replacer Powder | Powder | 33.0% | 40.0% | 1 part powder to 2 parts warm water | Complete diet to 6 weeks |
| PetAg Goat’s Milk Esbilac Puppy Milk Replacer Powder | Powder | 33.0% | 40.0% | 1 part powder to 2 parts warm water | Complete diet to 6 weeks |
| PetAg PetLac Powder for Puppies | Powder | 29.0% | 28.0% | 1 tablespoon powder to 2 tablespoons warm water | Intermittent or supplemental only |
| PetAg Esbilac Puppy Milk Replacer Liquid | Ready-to-feed liquid | 5.00% | 3.50% | Shake; no mixing | Complete diet if the puppy cannot eat solids |
| Royal Canin Babydog Milk | Powder | 33.0% | 39.0% | 10 mL powder to 20 mL water at about 50°C | Complete feed, birth to weaning (0–2 months) |
The Pet Bench Label Audit covered these five SKUs. Listed powder fat ran from 28.0% on PetLac to 40.0% on both Esbilac powders. That is a 12-point gap on one maker’s shelf.
Four of the five products use a 1:2 volume mix. Royal Canin writes that ratio as 10 mL powder with 20 mL water.
Only Royal Canin, in this set, prints DHA as 0.05% of the powder. Only Esbilac liquid prints EPA plus DHA at a 0.01% minimum.
PetAg lists 130,000 colony-forming units per gram on Esbilac powder. The same count appears on Goat’s Milk Esbilac and PetLac. AAFCO does not treat those organisms as essential nutrients.
Royal Canin lists fructo-oligosaccharides at 0.51% of Babydog Milk. It lists vitamin A at 25,000 IU per kg. It lists vitamin D3 at 1,500 IU per kg.
PetAg prints 5,098 kcal per kg for Esbilac powder. Goat’s Milk Esbilac powder carries the same calorie line. Dry powder is 31.6 kcal per tablespoon.
After a 1:2 mix, PetAg lists 13.2 kcal per tablespoon. Esbilac liquid is listed at 710 kcal per kg, or 10.96 kcal per tablespoon. PetAg lists PetLac at 13 kcal per tablespoon when mixed 1:2.
Powder versus liquid, and complete diet versus supplement
Use a complete-diet powder when the dam is gone. Use one when the litter cannot nurse enough. PetAg says Esbilac powder can be a complete diet through 6 weeks.
Goat’s Milk Esbilac carries the same complete-diet window. Royal Canin writes Babydog Milk as a complete feed from birth to weaning. That window is listed as 0–2 months.
PetLac is the outlier on PetAg’s own pages. PetAg says it is intended for intermittent or supplemental feeding only.
That is the cleanest split in this set. If the puppy has no dam’s milk, skip PetLac as the sole ration. The jar word “puppy” is not a complete-diet claim.
Goat’s Milk Esbilac is not a weaker Esbilac. PetAg lists the same 33.0% protein and 40.0% fat.
PetAg says the goat-milk version uses whole goat’s milk protein. It is aimed at sensitive guts. PetAg also says goat milk is lower in lactose than cow’s milk.
Esbilac liquid skips the mixing bowl. PetAg says an opened carton must be refrigerated. Discard it after 72 hours.
PetAg says the opened liquid may be frozen for up to 6 weeks. Move it out of the original carton first. Powder is the longer pantry hold.
Pick liquid for a single emergency night. Pick powder for a multi-week orphan watch.
Mixing, daily volume, and how long mixed formula keeps
PetAg’s Esbilac powder line is 1 part powder to 2 parts warm water. Whisk or shake. PetAg says not to use a blender.
Do not mix more than the puppy can finish in 24 hours. Reconstituted Esbilac must be refrigerated. Use it within 24 hours.
Goat’s Milk Esbilac follows the same mix and hold times. Unopened cans stay in a cool, dry place.
After opening, PetAg allows Esbilac powder at room temperature for up to 2 months. Then it allows 1 more month in the refrigerator.
Opened powder may be frozen for up to 6 months. Do not use it past the best-by date on the can.
Daily volume matches across PetAg’s Esbilac powder, Goat’s Milk Esbilac, and Esbilac liquid. Feed 2 tablespoons of liquid per 4 ounces of body weight per day. That is 30 mL per 115 grams.
PetAg says to split that day across feeds every 3–4 hours. Warm the liquid to room or body temperature. Do not microwave the liquid carton directly.
PetAg’s PetLac mix is 1 tablespoon powder with 2 tablespoons warm water. That makes about 2⅓ tablespoons, or 35 mL, of liquid.
PetAg says that PetLac amount feeds a 4-ounce puppy for about 1 day. The bottle-fed PetLac line is smaller per feed. It is 1 teaspoon, or 5 mL, per 4 ounces every 3–4 hours.
Royal Canin tells you to mix 10 mL of powder with 20 mL of water. Use low-mineral bottled water at about 50°C. Serve it lukewarm.
50°C is hotter than a warm-tap guess. Use a thermometer if you follow the Royal Canin card.
JAVMA’s feeding-direction warning still applies here. Volume on a label is not calories on a label.
Weigh the puppy every day. If weight stalls, change the plan in a clinic. Do not reach for grocery milk.
What not to pour in the bottle
Cow’s milk is the common panic substitute. It is the wrong species profile. It also carries the wrong lactose load for a neonate.
The same logic applies to leftover carton milk in a house with cats. Dairy myths cross species. See can cats drink milk for that mix-up.
PetAg says Esbilac and its kitten counterpart are not interchangeable. Puppy and kitten formulas are built for different species.
PetAg also says Esbilac does not contain colostrum. If the dam can nurse, PetAg wants the first 2 days on the dam.
Do not stretch a can past its best-by date. PetAg says both liquid and powder are perishable. Do not feed them after that date.
Do not treat grocery goat milk as Goat’s Milk Esbilac. PetAg says raw goat milk meets the needs of goat kids, not puppies.
PetAg lists three gaps versus its own formula. Raw goat milk has less protein per serving. It also has less fat and fewer calories.
Kitten milk replacer stays outside this article. Evaporated milk stays out too. Homemade mixes fail the Bench Completeness Rule.
Leaving the bottle without dropping calories
PetAg tells PetLac users to start a bowl at 4 to 6 weeks. Offer mixed formula in a shallow dish. Keep the bottle until the puppies lap well on their own.
That is the bridge to a wet mash. Use a species-labeled wet puppy food to thicken that mash. Start only after lapping is real.
Royal Canin’s complete-feed window runs through weaning at 0–2 months. PetAg’s complete-diet powder window ends at 6 weeks.
Plan the food switch on the label you bought. Do not assume every can ends on the same day.
Keep water in the room once lapping starts. Milk replacer is not a water bowl.
If stools turn loose, cut the volume first. PetAg’s PetLac note blames overfeeding for digestive upset. Smaller, timed feeds beat a bigger bottle.
FAQ
Can cow’s milk replace a puppy milk replacer?
No. Cow’s milk is the wrong species formula. The JAVMA paper already showed canine replacers vary from dog milk. Grocery milk is further off.
How much should an orphaned puppy get each day?
PetAg’s Esbilac powders and Esbilac liquid use 2 tablespoons of prepared liquid per 4 ounces of body weight per day. Split that volume every 3–4 hours. Weigh daily. JAVMA found that spoon rule can mean 12.3 to 40.5 kcal a day for a 100-gram puppy.
Is powder better than liquid?
Powder stores longer. PetAg keeps opened Esbilac powder at room temperature for 2 months, then 1 month chilled. Opened Esbilac liquid is discarded after 72 hours. Liquid wins only when you cannot mix.
Does Esbilac include colostrum?
PetAg says no. PetAg wants puppies to nurse the dam for at least 2 days when that is possible. Colostrum on many other labels is cow-derived. PetAg calls the benefit to a puppy hard to determine.
Can I feed kitten formula to a puppy?
PetAg says no. Each PetAg formula is species-specific. A kitten can does not become a puppy can by warmth or dilution.
When do I stop milk replacer?
PetAg’s complete-diet powders cover newborn to 6 weeks. PetLac’s bowl offer starts at 4 to 6 weeks. Royal Canin lists birth to weaning, 0–2 months. Move to a wet mash, then a puppy food, once lapping is steady.
How long does mixed powder last?
PetAg says refrigerate reconstituted Esbilac and Goat’s Milk Esbilac. Finish them within 24 hours. Mix only what that window can use. Royal Canin points you to the on-pack sheet after the 10 mL to 20 mL mix.
