A newborn puppy can go 2 hours without eating, while older dogs can go 5 hours comfortably before they feel like eating and drinking again. Going beyond this is not recommended. How long can a puppy go without eating? Newborn puppies can go two hours without eating until they are 3 weeks old after birth. Older puppies can go without food for up to 5 hours before having to eat and drink again.
Anything longer is not recommended. No puppy should go uneaten for more than a couple of hours beyond the required feeding periods. The only exception to this would be how long puppies can go without eating at night, since they will be asleep most of the time. Most puppies can last all night without having to eat.
Although there is always a bit of a litter, it's up to you to make sure they catch up with the rest of their siblings and that all puppies are at a happy and healthy weight. Sometimes your puppy doesn't feel like eating and that's OK as long as he only misses one or two meals (in a row); older puppies can go so long without eating and should be fine. That said, you'll need to increase the amount of puppy food you feed them each week, while they slowly stop using breast milk. At week eight, the puppy should be completely dependent on normal food, as the mother will begin to wean him from her milk.
Controlling their diet is very important in the first 8 weeks of life, and you should be alert if you notice that one of the puppies in your litter is significantly smaller than the rest. Having a new puppy is exciting, but when you bring your puppy home for the first time or when your dog has just had puppies, you need to be aware of their dietary requirements to make sure they are as happy and healthy as possible. At this age, their diet will consist mostly of puppy food mixed with water, but they will still need the nutrients in breast milk. While it may take a while for your new puppy to sleep through the night, there are a few ways you can help your puppy stay calm and relaxed during the night, allowing you to sleep longer.
Obviously, the whole guide here is age-related, as there is a big difference between how long a newborn puppy goes without eating before dying and leaving a 3-month-old puppy without eating for a few hours. Since it's not recommended that puppies take them away from their mothers before eight weeks of age, once your puppy reaches this age, it's usually time to go to a new home. If your puppy is between six and seven weeks old, it can go up to eight hours without eating; however, feeding at this stage is essential and feeding during this period of time is not recommended. The length of time a puppy can go without eating will depend on its age, as there is a big difference between the time a newborn puppy can go without eating before dying and leaving a 3-month-old puppy without eating for a few hours.
Not only do you want your puppy to be as healthy as possible, but you also want them to be as happy as possible, and lack of food will soon begin to affect their overall well-being and body. By the time your puppy reaches the four-week mark, he should be able to eat some puppy food and water, and some food still comes from the mother.
