Australian Shepherd Throwing Up Mucus: Read Before You Panic

An Australian Shepherd throwing up mucus is unsettling. Vomiting itself is a sign that something else could be causing this reaction from your Australian Shepherd.

There are different reasons why an Australian Shepherd can throw up yellow form, white foam, bile, clear liquid, or throw up after having a meal.

The question is, why does an Australian Shepherd throw up mucus specifically? 

Let’s dive into the reasons why an Aussie throws up mucus, whether you should be worried and what you can do about it.

An Australian Shepherd throwing up mucus is due to several reasons which include ingestion of toxins, food intolerance, intestinal blockage, inflammatory bowel syndrome, and intestinal parasites. An Australian Shepherd may also throw up mucus from coughing or regurgitation of mucus due to a medical condition.

Throwing up mucus is not a major medical concern however when the frequency of the vomiting increases or the appearance of other symptoms, it calls for immediate medical attention.

Our guide on Australian Shepherd throwing up or vomiting further explains what causes vomiting and what you can do to help your Aussie.

Australian Shepherd Throwing Up Mucus

What To Do If Your Australian Shepherd is Throwing Up Mucus

When your Australian Shepherd is throwing up mucus take note of the surrounding circumstances whether they also have other symptoms and if they’re throwing up the mucus after coughing or regurgitation.

If an Australian Shepherd is hacking up the mucus this means they were coughing up mucus not vomiting. An Aussie’s cough can be due to a respiratory infection (bacterial, viral, or fungal infection) or a medical condition.

Coughing can also be due to trying to get rid of something in their throat such as dust or a foreign object lodged in their throat.

Regurgitation on the other hand is different from vomiting. Unlike vomiting, regurgitation occurs suddenly without warning and an Australian Shepherd throws up undigested contents in the same form they were swallowed whereas vomiting produces partly digested stomach contents.

Regurgitation results in the expulsion of undigested food, fluids, or mucus from the throat.

By knowing this, you can relay this information to the veterinarian which will help to determine the underlying cause of the vomiting.

When to seek immediate medical attention

Increased vomiting
