Is Profuse Vomiting an Emergency?
Profuse vomiting is most definitely an emergency, particularly when associated with the inability to keep down water, blood in the vomit, depression or pain
This is very dangerous for any dog but especially when it comes to puppies or small dogs.

What makes it an emergency
With profuse vomiting, both the underlying cause and the vomiting itself can be a real danger.
Prolonged profuse vomiting can lead to dehydration and electrolyte abnormalities, both of which can lead to further complications.
Effects of severe dehydration include:
- Abnormal mental activity leading to confusion, depression, etc.
- Inability to form tears, which can cause corneal damage
- Low blood pressure can result in organ damage and failure (especially the kidneys)
- Gastrointestinal bleeding
- Seizures
- Permanent brain damage
It can eventually lead to shock and death.
As well as with profuse vomiting you’re looking at the potential of aspiration pneumonia and damage to the esophagus. With severe vomiting, it in itself needs to be addressed. Severe vomiting with or without blood in it is an emergency.

You also need to call your vet right away if:
- your dog is on medication that can have vomiting as a side effect
- you suspect your dog ingested a foreign body
- you suspect poisoning
Other signs indicating emergency include:
- severe lethargy
- unresponsiveness
- bloated abdomen
- abdominal pain
- pale, white, blue or gray gums
- difficulty breathing

Underlying cause
As for the underlying cause, the rule of thumb is that the more violent the vomiting, the more serious the problem causing it. You can be looking at anything starting with
- poisoning
- foreign body obstruction
- pancreatitis
- a severe infection or inflammation
- liver
- or kidney failure
Neither of the above are things I’d want to take my chances with.
