Bichon Frise Heart Conditions: A Screening Guide by Life Stage
Quick answer
What is the first sign of a heart condition in a Bichon Frise?
Usually nothing you can see. It is a murmur found by a vet at a routine visit, months or years before any change in behaviour.
A Bichon lives 14 to 15 years, which is long enough for a slow valve problem to become the thing that eventually limits them. Catching it early is mostly a matter of showing up for the stethoscope.
Owners who heard the word "murmur" at a routine visit and were sent home with no clear plan. Also owners of older Bichons who have started to notice a cough or a slower pace on walks and are not sure whether that is the heart or just fourteen years of living.

What this problem looks like
Cardiac findings in the Bichon Frise are usually discovered rather than reported — a vet hears something the owner never noticed. The realistic picture across the breed is a long healthy stretch, a possible murmur somewhere in the second half of life, and a smaller subset of dogs whose murmur eventually progresses to something that needs treatment. A minority of Bichons are diagnosed with a congenital defect as puppies.
Common triggers
- Routine auscultation at an annual or pre-anaesthetic examination
- A pre-surgical work-up before a dental procedure
- An owner noticing a soft night-time cough in an older dog
- Reduced stamina on the usual walk route
- A collapse or fainting episode, which is never routine
Most Bichons reach ten with no cardiac diagnosis at all. Degenerative valve change becomes measurably more common across small breeds after that point, and because this breed routinely lives to fourteen or fifteen, a fair number of Bichons live long enough to acquire a murmur. Having one is not the same as being ill from one — many carry a stable murmur for years without medication.
Why this happens
Breed factors
Size and longevity are the two relevant Bichon traits. At 12 to 18 pounds this is a small dog, and small breeds as a group are prone to degenerative change in the mitral valve rather than to the muscle disease that troubles large breeds. Longevity compounds it: a breed that commonly reaches 14 or 15 years simply has more time on the clock for slow structural change to accumulate.
Environment factors
Excess weight is the environmental factor with real leverage. A Bichon's exercise need is low and its appetite is not, so a couple of extra pounds on an 15-pound frame is proportionally large and adds work for the heart. Untreated dental disease is the second: chronic oral inflammation is unwelcome in any dog with a compromised valve, and dental disease is already on this breed's standard health list.
What you can do at home (once it is not an emergency)
When to talk to your vet
Same-day care for collapse, fainting, blue or grey gums, open-mouth breathing at rest, or a sleeping breath rate that has climbed past roughly 40 a minute — those point to fluid on the lungs and are an emergency, not a wait-and-see. Within a week for a new persistent cough, obvious loss of stamina, a swollen abdomen, or restlessness at night in a dog that used to sleep through. At the next routine visit for anything you have simply noticed and want documented.
At home, alongside your vet's plan
- Learn to count sleeping respiratory rate and log it weekly once anything cardiac has been mentioned.
- Keep body condition lean enough that you can feel ribs under the coat without pressing — the dense curly coat hides weight gain remarkably well.
- Switch a neck collar for a harness so lead pressure never lands on the trachea, which removes one common cause of coughing from the picture.
- Book the dental work your vet recommends rather than deferring it, and ask for a cardiac check as part of the pre-anaesthetic assessment.
- Keep a short written note of each visit's murmur grade so you and your vet are comparing like with like across years.

What to expect, and how you know it is working
Screening is a lifelong habit rather than a project with an end date. If a murmur is found, expect a re-check in six to twelve months to see whether it is stable. Dogs whose disease does progress typically do so over years, not weeks, and many Bichons diagnosed at nine are still comfortable at thirteen.
Success is a documented, tracked murmur that never turns into a crisis: a stable grade, a sleeping breath rate that stays in your dog's normal band, a lean body condition, and treatment that begins the moment imaging says it should rather than after an emergency admission.
What your vet listens for at each age
Cardiac screening in a small companion breed is not one test repeated forever. What matters shifts as the dog ages, and knowing the sequence helps you ask better questions at each visit.
- Puppy, 8 to 16 weeks: the question is whether a congenital defect exists. A loud murmur heard at the first vaccination visit is worth an echocardiogram before you commit to a neuter date, because anaesthesia planning changes.
- Young adult, 1 to 5 years: most Bichons in this window have a quiet chest. A murmur that appears here, with no history, deserves imaging rather than watchful waiting — it is out of pattern for the breed.
- Middle age, 6 to 9 years: this is when degenerative valve change starts showing up on auscultation in small breeds. An annual listen is genuinely the whole screening protocol at this stage.
- Senior, 10 years and up: the useful additions are a resting respiratory rate you count at home, a blood pressure check, and a chest radiograph if a murmur has been documented.
The one home measurement worth learning
If your Bichon has any documented heart finding, the single most useful thing you can do at home is count sleeping respiratory rate. Watch the chest while the dog is genuinely asleep, count each rise as one breath, and count for a full minute. Write the number down a few times a week.
Most healthy small dogs sit comfortably under 30 breaths a minute asleep. What you are building is a personal baseline, because the number that matters is not a textbook figure — it is the drift away from your own dog's normal. A Bichon that has slept at 20 for six months and is now sleeping at 34 has told you something before any cough appears.
What to do next about heart conditions in Bichons
If you think your Bichon has heart conditions, the plan is three steps: write down what you have seen and when it started, book a veterinary appointment rather than waiting for the next flare, and take video of the behaviour or symptom before you go — the thing you are worried about rarely happens in the consulting room. Screening in the parents covers skin allergies, patellar luxation, bladder stones.
What the vet visit should produce is a diagnosis and a written plan, not just reassurance: what is being ruled out, what the monitoring interval is, and which signs mean you come back sooner. Ask what the treatment costs across a year rather than per visit, because that is the number that decides whether you are managing this condition or reacting to it.
Between appointments, keep a short log — dates, what you saw, what changed. It is the single most useful thing an owner brings to a follow-up, and for heart conditions it is often what separates a clear pattern from a guess.
Coco's grade two, watched for four years
Coco was eight when a locum vet mentioned a grade two murmur almost in passing. Her owner, Priya, wrote the grade on the back of the vaccination card and asked for it to be re-checked each year. At nine and ten it was unchanged. At eleven the grade had moved up, so their vet took chest radiographs and started Priya counting sleeping breaths. The number sat around 22 and stayed there. At thirteen the rate crept into the low thirties over about three weeks. Priya rang before any coughing started, imaging showed early changes, and medication began that week rather than during a midnight emergency. Coco kept her short morning walks for another eighteen months.
Key takeaway: The value was not in the diagnosis but in the record. One number written down each year turned a vague finding into a trend, and the trend bought time to act calmly.
Frequently asked questions
Are Bichon Frises a high-risk breed for heart disease?
They are not among the breeds flagged for early or aggressive cardiac disease. The standard Bichon health list centres on skin allergies, patellar luxation, bladder stones, cataracts and dental disease. Cardiac findings do appear, but usually as the ordinary age-related valve change seen across small breeds rather than something breed-specific.
My vet heard a murmur but said not to worry. Should I push for more?
Ask two things: what grade it is, and whether the dog has any symptoms. A soft, low-grade murmur in a symptom-free middle-aged Bichon with a normal breathing rate is genuinely reasonable to monitor. Ask for it to be re-graded at every visit so a change gets noticed.
How often should an older Bichon's heart be checked?
Once a year through middle age, and every six months from about ten if anything has ever been documented. The examination itself is short. What makes it worthwhile is comparison across visits, which only works if the visits actually happen on schedule.
Does exercise damage a Bichon with a heart condition?
For most, no. A Bichon's exercise requirement is modest to begin with, and gentle daily walking supports muscle condition and weight. What you avoid is forcing a dog to keep going once it slows down or wants to stop. Let the dog set the pace and turn back early on warm days.
Is a cough always a heart problem in this breed?
No, and assuming so causes real delays. A small fluffy dog coughing could equally be tracheal irritation, kennel cough, collar pressure or dental-related. The heart-related cough tends to be soft, worse at night and lying down, and paired with a rising sleeping breath rate.
Do I need a cardiologist or is my regular vet enough?
General practice handles screening, monitoring and most routine cases well. A referral earns its cost when there is a loud murmur in a young dog, a fainting episode, an abnormal rhythm, or when treatment decisions depend on measuring chamber size accurately.

How much does a canine echocardiogram cost?
Expect a few hundred dollars in most regions, more at a specialty centre. It is a one-off diagnostic rather than a recurring expense.
Health
Should I change my Bichon's food for a heart condition?
Do not overhaul the diet on your own. Ask your vet before making changes, and mention it if you feed grain-free or boutique formulations.
Living
Can a Bichon with a heart murmur still climb stairs?
Almost always yes. Restricting a symptom-free dog is unnecessary and tends to cost muscle condition that the dog needs later.
Behavior
Does a heart condition change how my Bichon behaves?
Early on, no. Later you may see shorter interest in walks, restless positioning at night, or a reluctance to settle lying flat.
