Puppy Vomiting after Vaccination

Any time that you see your puppy vomiting, you should be somewhat alarmed. While vomiting is a relatively common occurrence in dogs throughout their lives, vomiting in puppies is a cause for concern. Due to their delicate bodies and developing systems, puppies are much more susceptible to different conditions than older dogs are, and it is often a much more serious problem if your puppy vomits. If he vomits immediately following a vaccination of some kind, that is cause for even more concern.

Causes of Puppy Vomiting after Vaccination

The most common cause of a puppy vomiting after a vaccination is an allergic reaction to the vaccination itself. This can be the first thing that you'll notice in a very severe reaction, which can even result in death. In other cases, your puppy may have been stressed or otherwise agitated during the time of the vaccination, and the vomiting can merely be a simple response to that impulse. The important thing to remember is that you can't tell exactly what the problem is with your puppy just by noticing that he's vomiting after a vaccination. Therefore, you should always have a vet monitor your puppy closely if you notice him vomiting shortly after he's been vaccinated.

Other potential causes of vomiting in puppies after vaccinations include:

  • Distemper
  • Intussusception
  • Standard virus or reaction to food that was eaten separately

Other Things to Notice

When you take your pet to the veterinarian's office after he has vomited following a vaccination, your vet will ask you several questions about your puppy's other behaviors. You'll need to be able to answer these questions if you want to provide him with the best possible chance of quickly diagnosing the problem with your dog. Therefore, you should note any of the following things that you see alongside or concurrently with the vomiting:

  • Presence of blood in the vomit
  • Diarrhea
  • Buildup of discharge around the nose
  • Loss of appetite
  • Facial swelling
  • Difficulty breathing

All of these are signs of severe issues that could also result in vomiting after a vaccination, so it's important that you be able to identify them properly. Note also how long exactly after the vaccination your puppy began vomiting, as this can indicate whether the vomiting was a result of the vaccination or whether it may have been something else entirely that caused it.

Treatment and Prevention

The treatment for your pet's vomiting will depend entirely upon the cause. With the help of your veterinarian, you'll determine what has caused your puppy to begin vomiting and then you can go from there when it comes to treating the issue.

If your puppy did experience an allergic reaction, you can often treat it with corticosteroids or antihistamines. You can also preemptively lower the chances of a reaction of this type for further vaccines by having your veterinarian administer Benadryl or another antihistamines to your puppy before giving him the vaccine.
