Vomiting, Regurgitation & Expectoration in Cats and Dogs

When your dog or cat is unwell and expels food, bile, or other substances, owners often label this as vomiting. However, distinguishing between vomiting, regurgitation and expectoration is vital for accurate diagnosis and care.

Understanding these three different processes helps you provide your vet with precise information, facilitating prompt and effective treatment. Although the topic can be unpleasant to discuss, recognising the differences can greatly improve your pet's health outcomes.

1. Recognising Vomiting in Pets

Vomiting is an active process involving the whole body. Your pet usually adopts a hunched posture with head lowered and neck extended. It will often drool or salivate before forcefully contracting its abdominal muscles to expel stomach and intestinal contents.

This process may produce bile, giving the vomit a yellowish-green colour, or partially digested food that is less recognisable. The act usually involves retching and can be accompanied by distinctive heaving noises. Pets may move backwards as they vomit, leaving a trail behind.

Vomiting is often associated with nausea and discomfort, making it clear something is wrong in the digestive tract.

2. Understanding Regurgitation

Unlike vomiting, regurgitation is a passive event. There is no nausea, heaving, or abdominal muscle involvement. Your pet simply expels undigested food or liquid from the oesophagus back into the mouth.

Regurgitated material is usually fresh and easily identifiable, sometimes coated with mucous but never containing bile. Pets do not typically show signs of distress and may even eat their regurgitated food. It often occurs soon after eating or drinking.

Regurgitation is common in dogs and cats with conditions affecting the oesophagus, such as megaesophagus, and should prompt veterinary assessment.

3. Identifying Expectoration

Expectoration refers to coughing up material from the respiratory tract, including mucus, phlegm, or occasionally food or water that has accidentally entered the windpipe. It always begins with a cough and involves material originating from the lungs or airways, not the stomach or oesophagus.

This material looks different to vomit or regurgitated food and is often sticky or frothy. Persistent coughing fits leading to expectoration can occasionally cause vomiting due to stomach irritation, but this is uncommon.

How These Differences Help Your Vet

Your vet will rely heavily on your accurate description of your pet’s symptoms to identify whether the issue is gastric, oesophageal, or respiratory. Bringing a sample of the material your pet has expelled can help, but if you can describe the process correctly, this may not be necessary.

Knowing these distinctions contributes to responsible pet ownership by enabling timely professional intervention and reducing the risk of complications. If your pet displays any form of repeated vomiting, regurgitation or coughing with expectoration, seek veterinary advice promptly.

Frequently Asked Question: Why is it important to differentiate between vomiting and regurgitation in pets?

Quick Answer: Differentiating vomiting from regurgitation helps vets pinpoint the affected organ and underlying cause, enabling appropriate treatment.

Vomiting involves active stomach contractions and usually indicates a gastrointestinal problem, while regurgitation is passive, involving the oesophagus and often signifies oesophageal disorders. Misidentification can delay diagnosis and prolong your pet’s discomfort. Being observant and accurate benefits your pet’s health and recovery.

Conclusion

Vomiting, regurgitation and expectoration may seem similar but are distinct in cause and presentation. Recognising these differences empowers you as a pet owner to support your vet in diagnosis and care, ultimately improving your beloved cat or dog’s wellbeing.
