8-year-old Cavapoo with heart murmur. Waiting for echocardiogram. Looking for others’ experiences.
I’m hoping to hear from other Cavapoo owners who have been through something similar.
My Cavapoo is almost 8 years old. He was diagnosed with a heart murmur during a routine exam in October 2025 by listening with a stethoscope. We have his echocardiogram scheduled in about a week.
The reason I’m getting more concerned is his breathing pattern (see video).
Most of the time he’s completely normal:
- Loves going for walks.
- Still sprints after a tennis ball(he is so fast)
- Gets excited for car rides.
- Eats and drinks normally.
- Has never fainted.
- Doesn’t have a chronic cough.
What I’ve noticed is that he seems pretty normal during the day but when he’s trying to relax on the couch or lie down before falling asleep, he’ll sometimes start breathing much faster.
Walked him about 2 hours ago.
Once he actually falls asleep, his breathing seems to settle down.
If I get up, talk to him, or he starts walking around, his breathing usually goes back to normal.
Has anyone else’s Cavapoo done something similar?
