A step-by-step guide to preparing puppy milk at the right temperature, with safe storage tips for breeders.
When hand-rearing puppies, preparing milk correctly is essential for their growth, digestion, and overall health. Using the right water temperature, clean utensils, and accurate measurements ensures every feed is safe and nutritious.
Start with Pre-Boiled Water
Always use pre-boiled water. Boiling the water first kills bacteria and ensures it’s safe for young puppies, whose immune systems are still developing.
Store cooled, pre-boiled water in clean, lidded bottles or containers for future use.
The Ideal Mixing Temperature
To make mixing easier, keep both hot and cold pre-boiled water on hand. You can then combine them to achieve the perfect temperature for each batch.
The optimal water temperature for preparing puppy milk is around 40 °C. At this temperature, the milk powder dissolves easily, and the finished milk will be close to the ideal feeding temperature of 35–37 °C — similar to a mother’s milk.
If the water is too hot, it can cause nutrient loss or curdling. If it’s too cold, the powder won’t dissolve properly, resulting in uneven consistency.
Use a Thermometer for Accuracy
A clean, fast-read waterproof thermometer is invaluable for checking the water temperature before adding the powder. This ensures the formula isn’t too hot (which could destroy nutrients) or too cold (which may cause clumping and feeding reluctance).

Measure Precisely
Accuracy is key. The most reliable way to measure ingredients is with digital scales, which are far more precise than measuring cups or spoons.
You can also use manufacturer-supplied scoops, but this may limit batch size flexibility. Remember, 1 mL of water equals 1 g, so you can weigh liquids and powders easily on the same scale.
Simple calculations will help you determine how many grams of milk powder you need per mL of water.
Always follow the manufacturer’s directions for the correct ratio of powder to water — unless otherwise instructed by your veterinarian. In some cases, a vet may advise a diluted formula for conditions such as dehydration or diarrhoea.

Mixing
There are several effective ways to mix milk powder and water — the goal is simply a smooth, lump-free consistency.
If using Method 2, the milk may initially be frothy; let it settle for a few minutes before measuring or feeding.
Method 1: Paste (best for small quantities)
Measure the required amount of milk powder and pre-boiled water. Add a small portion of water to the powder to form a smooth paste, then gradually mix in the rest until fully combined.
Utensils: container, spoon, small spatula or whisk.
Method 2: Direct (requires shaking or agitation)
Measure the required milk powder and pre-boiled water. Add the powder to the warm water, let it dissolve briefly, then shake or mix thoroughly.
Utensils: protein shaker bottle, blender, stand mixer, or stick blender.
Batch Preparation and Storage
Preparing larger batches can save valuable time during busy feeding periods. Once prepared, store puppy milk in the refrigerator for up to 24 hours. This allows you to make it once daily and warm each feed as needed.
Any leftover milk can be offered to the mother dog so nothing goes to waste.
For longer storage, freeze puppy milk for up to two weeks. This is particularly useful for breeders with multiple litters or overnight feeding schedules.
Smart Storage Tips
-
Divide milk into individual feed quantities before refrigerating or freezing — this avoids reheating or thawing excess milk.
-
Capped bottles or syringes (such as Miracle O-Ring or ENFit) are convenient for both storage and feeding.
-
Ice cube trays with lids work well for freezing small, pre-measured portions.
-
Always label containers with the date and amount for easy tracking.
Once thawed and warmed, discard any unused milk and wash all feeding utensils thoroughly.
Milk should not be reheated more than once after it’s made, as repeated heating encourages bacterial growth and nutrient loss.

Final Tip
Cleanliness, accuracy, and correct temperature make all the difference in successful hand-rearing. With a good thermometer, digital scales, and smart preparation habits, you’ll ensure that every puppy gets the nutrition and care it deserves.
