Auscultation

Auscultation is the medical listening to body sounds with a stethoscope, one of the first examinations your vet performs at every visit.

When the vet places the stethoscope on your dog’s chest and abdomen, they listen for heart rhythm, breathing sounds and intestinal movements. These sounds reveal whether the heart, lungs and digestion are working normally.

What does the vet hear when listening?

The normal dog heart makes a rhythmic “lub-dub”, like an even beat. Breathing sounds calm and even, the gut makes subtle gurgling noises.

It becomes problematic with heart murmurs between normal beats, crackling in the lungs or complete silence in the abdomen. A heart murmur occurs when blood flows turbulently through defective heart valves. Crackling sounds indicate fluid in the lungs, for example in pneumonia.

Whistling breathing sounds indicate narrowed airways, as they occur with allergic reactions. Too loud gut noises speak of digestive stress, complete silence for a possible bowel obstruction.

When should you ask questions as an owner?

If the vet listens longer than usual at one spot or repositions the stethoscope multiple times, they have heard something. Do not hesitate to ask: “Is there anything unusual?”

Especially in older dogs, slight heart murmurs are common, but not all require treatment. An experienced vet can assess for you whether a finding needs monitoring or immediate treatment.

After anaesthesia or with respiratory problems, the vet listens particularly thoroughly. Here it is about detecting complications early.

What auscultation cannot do

Listening gives only a first impression. A normal auscultation finding does not rule out heart problems, some diseases are silent. Conversely, harmless heart murmurs in puppies can be completely normal.

If findings are unusual, further examinations usually follow: X-rays for lung problems, echocardiogram for heart murmurs, blood test for digestive disorders. Auscultation is the first step, not the final diagnosis.
