People often get confused with regurgitation as vomiting in dogs. Vomiting is an involuntary act of forceful expulsion of food from small intestines or stomach through the mouth and sometimes the nose. Regurgitation is a passive act of expulsion of undigested food from mouth.

Difference between Vomiting & Regurgitating are:

  1. Vomit is an active act where dog is drooling, making retching sounds and having stomach contractions. On the other hand, regurgitating is a passive act and does not have any warning sign.
  2. When dog vomits, food is generally semi-digested, while in regurgitation, food is not digested.
  3. While vomit is in chunky, granular, or liquid format, regurgitating is always in the cylindrical shape of the esophagus.

Common Causes for Regurgitation:

  • Overeating of food
  • Eating food quickly
  • Anxiety or over-excitement after eating food
  • Dilated esophagus that does not effectively move food to the stomach.

The vomit might have coffee coloured granules which generally denotes blood in vomit. This type of vomit generally happens when the dog digests something which is not suitable for the dog to digest like chocolate, garbage etc.
