As with humans, puppies vomiting can either be nothing to worry about or a sign of an internal body process gone wrong. For young puppies, vomiting is even more dangerous, given that it easily leads to dehydration and death — especially when the cause is not identified and treated.
If your pup has been vomiting more frequently recently, you ought to be worried. There are tons of reasons why that could be happening, and you need to know them. Some of them are listed below.
But first, a primer on puppies vomiting. It occurs with the help of strong abdominal contractions that result in the expulsion of stomach contents. When vomiting is triggered by the pup’s brain, it starts to swallow just as fast as it salivates. Just as the stomach muscles contract — and you can see it happen — the pup’s throat expands and it opens its mouth to finish the expulsion.
Vomiting shouldn’t be confused with regurgitation, though. Both involve the release of the stomach’s contents, but regurgitation happens without contractions of any kind.
So why do pups vomit?
Eating too much, too fast
Does your pup swallow all its food in minutes like it is in a race? That’s why it could be vomiting frequently. Fast eating is a major trigger for vomiting, especially if the puppies are subjected to exercise right after.
Eating the wrong thing
While gastric irritation is more common in older dogs, it can also affect puppies when they eat anything other than their food. Grass and inedibles like plastic and spoiled food are some of the biggest triggers of gastric irritation-induced vomiting.
You might love taking them places, but pups also suffer from motion sickness during car rides and other motion-inducing situations. That easily triggers vomiting.
One of the major signs of the canine distemper virus (also known as the canine parvovirus) in puppies is frequent vomiting. Don’t worry, though. You can prevent this with proper vaccination. If the vomiting is accompanied by serious diarrhea or blood and the pup looks weak and unhappy for a long period of time afterward, that could be a sign of another stomach infection like roundworms. You must contact the vet immediately.
Even puppies suffer from bloating and it makes them very uncomfortable. In addition to restless, shallow breathing, whining and a rapid heartbeat, vomiting is another sign that your pup is struggling with bloat. This is more common in deep-chested breeds.
When is it serious?
Like with humans, vomiting can happen without cause for alarm. If your pup vomits once a day or twice a week and doesn’t appear unhappy afterward, there’s no need for alarm. But if your pup vomits more than two times a day or for more than two consecutive days in a week, call your vet immediately. That could be a sign of much deeper illness that can result in sudden death.
