How Long can a Newborn Puppy Survive Without Food?

As soon as a puppy is born, he is promptly given a bath before dinner. A newborn puppy is born blind and immobile, but this won’t deter him from finding a meal.

Eating is crucial for a newborn puppy as his body and organs are developing. Food provides energy to newborn puppies that keep them warm.

In some emergency cases, the puppy can go for several hours after birth without eating. They survive this scenario as they still retain nutrients from the placenta.

However, for a normal newborn pup, fasting for 2 hours between meals is quite common. The mother dog needs to take breaks from feeding, and the puppy needs time to digest and sleep, of course.

This type of feeding schedule is appropriate until 3 weeks of age.

The length of time between feedings strongly depends on the puppy’s age. A dog’s appetite increases as they age.

At three weeks, young puppies can sustain up to 3 hours between feeding on their mother’s milk. After 4 weeks, most puppies can sustain it up to 4-5 hours. However, this is not recommended as a new puppy is still in his critical developmental stages.

Withholding puppy food from your young pups may cause them to go ravenously hungry. Frequent bouts of hunger may cause organ failure among young pups and even on adult dogs.

At about this age, slowly introduce your puppy to puppy food. Start feeding him softened kibble. Consult with the local vet on what is best for your pup, depending on his size and breed. It is also about the same time your pup will seldom nurse on the mother dog as he self-weans.

Over time, transition your dog to solid food. By about 8 weeks, Mom will have had enough nursing. At this time, your puppy should almost be completely on a dry food or puppy kibble diet.

He should be on a consistent diet, eating 3 or 4 times per day. It is recommended to keep the diet at regular intervals to avoid any upset stomach and other digestive system problems. When this happens, immediately seek medical help or visit the vet. Missed meals will be until about 12 weeks of age, unless sleeping, which we will cover later.

Water is essential to life and growth for all living beings. Fortunately, puppies receive the majority of their water intake through milk or formula for the first 4 weeks.

Never let it get to that point by always providing your dog clean and fresh water.

After 12 hours, the body will enter dehydration, and this strain can cause immense stress on vital organs. After 24 hours, the dehydration will continue to damage the organs. Your dogs will lose the ability to cool themselves and regulate their temperatures.

If your puppy has not drunk any water in 24 hours, it is highly recommended to take them to a veterinarian as soon as possible.
