The 8 Best Puppy Milk Replacers

1. PetAg Esbilac Liquid Milk Supplement – Best Overall

PetAg Esbilac Liquid Milk Supplement provides a complete and nutritionally-balanced food source for puppies that’s highly palatable and digestible. This formula can also be used as a supplement for pups that can still nurse, as well as stressed adult dogs that need an extra boost of nutrients. This formula provides the necessary vitamins, minerals, and amino acids needed to get puppies off to a healthy start.

Since this formula is in liquid form, there’s no need to mix. Simply open and follow the recommended serving sizes. One drawback is liquid formula doesn’t have a long shelf life after opening, but the good news is that this product comes in an 11-ounce can at a great price. Unopened cans can be stored in a cool, dry place for up to 6 weeks, and they should last up to 72 hours after opening.

Occasionally, cans may arrive dented, and if this happens, you can call the manufacturer. Nonetheless, PetAG is a trusted brand within the industry with over 70 years of expertise. With the reasonable price and the necessary vitamins, minerals, and amino acids, we feel this product is the overall best puppy milk replacer.

2. Hartz Powdered Milk Replacer Formula – Best Value

If you’re looking for a powdered formula, then Hartz Powdered Milk Replacer Formula may be a good option. This product comes in a 12-ounce jar formulated with real milk to perfectly match mother’s milk. You can rest assured the puppies will receive the necessary ingredients: protein for optimal growth, calcium for strong bones, magnesium for muscle and heart health, vitamin A for eye development, linoleic acid for healthy skin and coat, antioxidants, and omegas that cover all their health needs.

Not only is this formula designed to match the mother’s milk, but it is also suitable for pregnant or nursing moms and seniors who need a boost of nutrients. It’s easy to digest and mix, but be sure to mix at room temperature for the best results. With the nutritional benefits for newborn puppies, pregnant or nursing mothers, and seniors at an affordable price, we feel this product is the best puppy milk replacer for the money.

We need to point out that this product contains BHA and BHT, which are preservatives that slow down the oxidation process. These preservatives are a controversial ingredient.

3. 3. Zesty Paws Puppy Milk Replacer + Colostrum — Premium Choice

Zesty Paws Puppy Milk Replacer + Colostrum is a veterinarian-formulated powder designed to give newborn and young puppies a healthy start when a mother's milk is unavailable. What sets this formula apart from many competitors is the inclusion of bovine colostrum, which is the nutrient-rich first stage of breast milk production that helps provide temporary immune support. The formula also contains prebiotics and probiotics to promote healthy gut flora, along with omega-3 and omega-6 fatty acids (including DHA) to support cardiovascular health, skin, and coat development. It mixes easily by combining one part powder with two parts warm water, and the prepared liquid can be refrigerated for up to 24 hours.

This formula is suitable for puppies up to six weeks of age and can also be fed to pregnant or lactating mothers who need a nutritional boost, as well as senior dogs. Zesty Paws is one of the top-selling dog supplement brands on Amazon, and this product carries their standard of quality with ingredients sourced from the U.S. and around the globe. Some users have reported that the powder can be a bit lumpy when mixed and that the 12-ounce bag may feel pricey for the amount provided. That said, puppies and dogs tend to enjoy the taste, making feedings straightforward.

Once it’s opened, you can store it in the refrigerator for up to 14 days, and it comes in a 10.5-ounce container.

Sometimes the product may come half-full and is not returnable. The powder may clump when stirring, but shaking the can before mixing helps the powder dissolve.

6. 6. Royal Canin Babydog Puppy Milk

Buyer's Guide - Finding the Right Puppy Milk Replacer

Caring for newborn puppies where the mother has rejected them or died can be both rewarding and a little frightening. In these situations, you want to ensure the precious pups get off to the healthiest start possible, and selecting the best puppy milk replacers will do just that.

If you need guidance on finding the right puppy milk replacer, we suggest you speak to a vet.

Now that we’ve examined our top 8 picks for the best puppy milk replacer, let’s further examine what to look for in a product.

Preservatives

Newborn puppies are fragile, and they need the utmost nutrition right after birth. Since they are not getting their mother’s milk, it’s imperative to provide them with the most natural formula possible with no preservatives.

The mother’s natural milk certainly doesn’t have preservatives, so there’s no need to feed the little newborns preservatives of any kind. A couple of products mentioned above contain the chemical antioxidants BHA and BHT. The FDA has approved these preservatives for human consumption but many people are still cautious.

Colostrum

If the formula contains colostrum, a source of nutrients and immunoglobulin, then that’s terrific! Colostrum is naturally produced from the mother’s mammary glands during the first two days of birth. It is vital for puppies to get colostrum to ensure they survive the first couple of days of life.

Most of the puppy milk replacers we reviewed contain colostrum, and we highly recommend going with a product with this precious, life-saving nutrient.

Shelf Life

Powdered formula has a longer shelf life than its liquid counterpart, and most people find that going this route is more cost-effective. However, be sure to read the instructions before purchasing to ensure you don’t waste a lot of the product because some of them only last up to 24 hours in the refrigerator after opening.

Omega Fatty Acids

Omega 3 fatty acids, also known as DHA, are important for brain and eye development, so be sure to check the ingredients for this valuable component.

Mixing

Sometimes a product doesn’t mix well, which can be frustrating. Sometimes the powder will clump together and settle on the bottom before you have the chance to feed. In our reviews, we try to ensure you’re aware of this on certain products. Don’t give up, though, because sometimes it just takes patience.

Prebiotics and Probiotics

Prebiotics and probiotics aid in digestion for newborn pups. Prebiotics supply fiber to promote good bacteria already in the colon, and probiotics are healthy bacteria in the gut that helps prevent disease. It also promotes a strong immune system and helps fight harmful pathogens. We highly recommend purchasing a formula with these added.

Vitamins and Minerals

Newborn pups need a vast amount of calories and protein to get off to a healthy start. Be sure to look for vitamins and amino acids, too.
