Ideally, puppies should get their nutrition from their mother’s milk, but this is not always possible. You should always attempt to get the puppy to take their first drink from the mother’s teat.

This is because it contains many nutrients that are vital for their health and immune system development. This is known as colostrum and even if the mother only has a little, try to get your puppy to drink some.

Best Puppy Milk Replacer Buyer’s Guide

Easily digestible

Newborn puppies have very sensitive stomachs and their milk needs to be easy  to digest. They are also very likely to suffer from allergies, so the easier the milk is on their stomach, the better it is for them.

Goat’s milk is very easy for your puppy to digest. This is because it contains less lactose than cow’s milk and is closer to canine milk. 

Fortified with vitamins and minerals

There are many micronutrients that occur naturally within the mother dog’s milk. These are vital to your puppy’s health and development. If your puppy is not getting these naturally from their mother, you will need to supplement them in their milk replacement. 

Vitamin A helps with your puppy’s vision and eye health. It does not only help their ocular region but also serves to improve the condition of their skin and coat, making them appear healthy and shiny.

Vitamin B12 is vital to the function of your puppy’s nervous system. It also ensures that their immune system develops properly and becomes strong. This vitamin also helps with the efficient metabolism of carbohydrates and proteins. 

Vitamin E is used in the growth and development of muscles. It also serves as an antioxidant, working to protect your puppy’s immune system and protecting the cell membranes. 

Vitamin D3 also works to strengthen the immune system, at low levels. It also helps to strengthen the muscles of the heart, improving cardiovascular health. 

Calcium is vital for your puppy’s bone and teeth health. It also helps to ensure your dog’s blood clots correctly. It also assists with their muscle contraction and elongation.

Zinc is the second most commonly needed mineral in dog’s bodies. A deficiency can result in skin and digestion problems. It can also cause the immune system and thyroid to function incorrectly. 

Iron supports enzyme function in your dog’s body. It is also used to help hemoglobin in the red blood cells transport oxygen around the body to help create energy.

Phosphorus is important for the healthy function of the kidney. This allows their bodies to flush any toxins out via the urine. It is also used to help their muscles contract.

Iodine supports the metabolism in your dog and maintains a healthy level of thyroid hormones. These are used to maintain weight, energy, and emotional state.

Amino acids and fatty acids are essential to the development of nerves, muscles, and tissues within your puppy’s body.

Calorie dense

Your puppy is growing rapidly and needs a lot of calories to sustain themself. They have very small stomachs and cannot ingest large volumes at once. This means that anything they eat or drink needs to be calorie dense to make sure they are receiving adequate nutrition. 

It is vital that you feed your puppy with a calorie-dense milk to ensure they do not get hungry. This is particularly important in the first few weeks of their life, as this is when the growth is most fast paced.

The calorie density is labeled in calories per kilogram, and a good ballpark figure is around 1460 kcal/kg. 

Powder or liquid

Powder formulas are a dehydrated version of milk and only contain minimal amounts of moisture. This means that they will keep for much longer than their liquid counterparts.

This is because the lack of moisture slows the bacterial growth and so bulk purchasing is easier. They must be mixed with a liquid prior to serving, meaning that they are not quite as convenient. They are the most commonly found milk replacement.

Liquid milk replacements are pre-made to be ready to give to your pet. They go off much faster due to the high moisture content. This means that it cannot sit in the cupboard for a long time and must be used quickly to prevent upsetting your puppy’s stomach.

How old is your puppy?

Newborn puppies, between the ages of 0-8 weeks, need a very specific type of milk.

Puppy milk replacements should state the optimal age range it is designed for. Most can be used for the duration of the weaning period, but it is a good idea to check this.

Protein content

Your puppy needs a lot of protein to support their growth. Ideally, the puppy milk replacer that you feed them should have a protein content of around 30%. Anywhere between 25% and 35% protein content is a good range to stay within. 

This protein is used to help grow your puppy’s muscle tissue, including that of their internal organs. If your puppy is still having some of their mother’s milk and the replacement is being used as supplementation, the protein content can be towards the lower end of this range.

If this is their only nutrient source, you should look for a higher protein content. 

Fat content

Ideally, your puppy milk will contain anywhere between 25% and 40% fat. Different puppies will prefer different fat contents, so don’t be afraid to try a few and see what yours prefers. 

Fat is used as energy in your puppy’s body. Dog milk is naturally a fatty liquid, and so the milk replacement must have a high fat content too. Again, the importance of the fat content depends on whether they have maternal milk readily available. 

Good puppy milk replacements should have relatively equal quantities of fat and protein. 

Probiotic bacteria

The delicate stomach of your puppy needs careful care. They take some time to mature enough to allow them to break down the milk efficiently.

If you choose a milk replacement with added probiotic bacteria cultures they can break down the milk more easily. 

This is not essential but can help prevent your puppy from getting an upset stomach. 


Your milk replacement should be made from real ingredients. Good things to include are dried whole milk, skimmed milk, dried whey, protein isolates, animal or vegetable fats, and egg products. 

The milk should not contain too much sugar or salt, as this is not good for your puppy’s overall health. Try to ensure the milk has natural ingredients to prevent feeding low-grade milk to your puppy.

Shelf life and storage 

It is important to pay attention to the shelf life of your puppy milk replacement. This is to ensure that you do not incur unnecessary waste. Feeding your puppy milk replacements that have expired can lead to health issues and can upset your puppy’s stomach. 

Check to see whether your milk replacement needs to be stored in the refrigerator or an airtight storage container. Improper storage can lead to premature spoilage, wasted money, and wasted products. 


Weak and flimsy packaging is highly indicative of poor quality. Products packaged like this are very prone to spoilage and should be avoided.

Good packaging will be sturdy and resealable so that the puppy milk replacement will stay fresher for longer.

Artificial fillers

Artificial fillers are not good for your puppy, particularly if they are very young. Their bodies are not developed enough to process these unnatural ingredients. Their immune system is also still developing and this can cause them to become ill. 

Try to stick to puppy milk replacements that are made primarily from naturally occurring ingredients. 

Frequently Asked Questions

Why might you need to give a puppy a milk replacement?

If the puppy’s mother does not appear to have enough milk or the puppy does not have access to sufficient nutrition you should consider using a milk replacement to supplement their diet. This will ensure they get sufficient calories and nutrients to survive. 

If the mother is unwilling to allow the puppies to nurse, you should also consider a puppy milk replacement. Likewise, if you find an orphaned puppy it is vital that you get some nutrition into them as soon as possible. 

How do I give the puppies milk replacer?

You will need to get a feeding bottle ready that has been sterilized. Hold the sharp end of a small needle in the flame of a lighter to sterilize that too.

Make 2 small holes in the nipple of the bottle with the needle. Ensure these are not too big as this can cause your puppy to take in the milk too quickly and can lead to it aspirating the milk. 

If you are using milk replacement powder, you should make it up as per the instructions on the packaging. Ensure that there are no lumps of unmixed powder as this can block the holes in the nipple or cause your puppy to choke. 

If your puppy gets constipated, add more water to the formula. If they have diarrhea, add less. Add to the sterilized bottle.

Warm the milk formula by placing the bottle in a bowl of hot water. Particularly in newborn puppies, they struggle to regulate their body temperature, and feeding them cold milk can result in hypothermia.

You should try to make the milk the temperature of a warm bath – around 99 degrees Fahrenheit.

Gently allow your puppy to suck the milk out of the bottle. Try not to overfeed them, as this can lead to digestive issues. Try to feed them little and often, around every 2 to 3 hours.

What other dogs may benefit from a supplemental milk replacement?

If your dog is old or ill they are unlikely to be eating enough to get sufficient nutrition. This is a great occasion to use milk replacements to supplement their diet and prevent them from becoming ill or malnourished. 

Pregnancy also puts a lot of strain on your dog, and supplementing their diet with a milk replacement helps to ensure the health of the mother and pups.

Why should you not give puppies cow’s milk?

Particularly in the early stages of life, your puppy’s stomach is not very developed and they commonly suffer from allergies.

Many dogs are lactose intolerant and cannot handle large quantities of cow’s milk without having gastrointestinal discomfort. Excessive consumption could lead to vomiting and diarrhea. 

Cow’s milk is very high in fat and sugars, as it is designed to sustain the growth of a cow. This can cause your puppy to become overweight and could even lead to them developing pancreatitis if allowed it regularly.
