Adult Heart Health Screening for Mixed Breed Dogs

Clinical context

Why this stage is different for Mixed Breed Dogs

Adult Mixed Breed Dogs should have heart auscultation at every physical. Some lines in this breed need earlier echocardiography, Holter monitoring, or blood pressure checks. Do not wait for collapse. Store every murmur grade, echo PDF, and medication start date in chronological order - that is the difference between a useful cardiology referral and a shoebox of paper. Pair cardiac notes with weight: extra pounds are afterload the heart did not ask for.

Dated protocol

Adult Mixed Breed Dog screening timeline

1. Annual

   Auscultation + history

   Resting respiratory rate at home (count while asleep) is free surveillance.

2. If murmur

   Echo decision

   Grade, timing, and breed risk decide urgency - not “we’ll watch it.”

3. Diagnosed

   Staging

   Archive ACVIM stage, radiographs, blood pressure, and kidney values before meds start.

4. q 3-12 mo

   Recheck

   Cardiology cadence depends on disease. Put the next echo in the same reminder system as vaccines.

Cardiac vault protocol

1. Resting respiratory rate log (goal typically <30/min asleep unless your cardiologist sets another number).
2. Every ECG, Holter, and echo as PDF - not a portal screenshot that expires.
3. Medication list with mg and time, including missed doses.
4. Cross-link individual risk based on size and lifestyle so orthopedic limping is not misread as “just getting old.”
5. Anesthesia history - last echo date must travel with the dog to dental procedures.
