Heart disease in dogs
A murmur is a sound, not a sentence. How to count your dog’s sleeping breathing rate, the number cardiologists use.
Bloodwork cannot show a murmur, valve shape, chamber size, or heart rhythm. A normal blood panel can exist beside meaningful heart disease because listening, imaging, and electrical recordings answer different questions.
BarkLens keeps the imaging history, medication list, laboratory results, and owner observations in one record.
BarkLens doesn’t diagnose. Your vet does.
What blood tests can show
NT-proBNP is released when heart muscle is stretched. Cardiac troponin I can rise with heart muscle injury. Kidney values and electrolytes also matter because heart medications can affect them.
Why heart disease is described in stages
ACVIM guidance separates dogs at risk from dogs with structural disease and from dogs with signs of heart failure. The date a murmur was first heard and what the most recent imaging showed help preserve that history.
A recommendation to watch and repeat testing can be a plan rather than inaction. Keep the stage, imaging date, and next scheduled check together.

A veterinarian may ask for sleeping respiratory rate, exercise tolerance, coughing, or details around a fainting episode. The owner records the observation; BarkLens keeps it beside the chart.
If you believe your dog is having a breathing or other medical emergency, contact a veterinarian or emergency clinic now.
A practical plan
Create a heart-history log
Use the number or instructions your veterinarian gives you, not a number invented by the app.
- Sleeping-breath counts with date and time
- Coughing, exercise, or fainting observations
- Medication starts, stops, and label instructions
- Imaging reports, kidney values, electrolytes, and blood pressure
Questions worth asking
Bring the next question, not just the latest number.
- What stage is recorded for my dog?
- What should I count or write down at home?
- Which medication changes require laboratory follow-up?
- What would make you want to see my dog sooner?
