Boxer health overview

The big picture

Lifespan and outlook

10–12years

Boxers typically live 10–12 years.

Most Boxers whose hearts and elbows are checked get normal results. Like every breed, they have a few health problems that run in the family, and most are easier to manage when caught early.

Everyday habits

A few everyday habits do a lot of the work.

  • Keep your Boxer lean, and keep it cool in hot weather.
  • Check the skin for new lumps every month, brush the teeth often, and book a checkup every year that covers the heart, eyes, thyroid and skin.

Common Boxer health conditions

Worth knowing

Each entry starts with a condition the breed is known to be prone to, then what you might notice and what helps.

This list is not exhaustive or official. Keep asking your veterinarian as your puppy grows.

01

Heart rhythm (ARVC)

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heart-muscle disease of adult Boxers that upsets the heartbeat.

What you might notice

Fainting, weakness or tiring quickly are signs to take to your vet.

What you can do

A yearly heart-rhythm recording, called a Holter, picks up irregular beats early, starting in young adulthood. Many dogs do well on medicine for years.

02

Heart murmur from birth

Subaortic stenosis is a narrowing just below a heart valve that a puppy is born with.

What you might notice

A vet hears it as a murmur, sometimes only as the puppy grows.

What you can do

A heart scan (echocardiogram) checks any murmur, and mild forms allow a normal life. Soft, harmless murmurs are also common in puppies and usually fade.

03

Lumps and cancer

Cancer is the leading known cause of death in Boxers, and skin tumors called mast cell tumors are common.

What you might notice

Look for any new lump on or under the skin.

What you can do

Check the skin every month, and have your vet sample any new lump. Boxers often get the lower-grade form of mast cell tumor, so finding one early helps.

04

The Boxer ulcer

The Boxer ulcer is a sore on the clear front of the eye that does not heal normally, which vets call SCCED (spontaneous chronic corneal epithelial defect).

What you might notice

Watch for squinting or tearing, often in middle age.

What you can do

See your vet promptly, because a minor procedure usually treats it. A yearly eye exam by a veterinary eye specialist tracks other eye changes too.

05

Thyroid

An underactive thyroid (hypothyroidism) is often caused by the body's own immune system.

What you might notice

Signs include a thinning coat, weight gain and tiredness.

What you can do

A daily hormone tablet manages it, and a blood test keeps track of it.

06

Hips

Hip dysplasia is a hip joint that forms loosely or poorly as a puppy grows.

What you might notice

Watch for limping, which usually shows between 4 months and a year.

What you can do

Keep your puppy lean, and skip forced exercise while its bones are growing. Hip X-rays can check the joints once your Boxer is grown.

Less common conditions in the Boxer

Less common

Degenerative myelopathy slowly weakens the hind legs late in life, without pain, and a DNA test shows a puppy's risk.

Granulomatous colitis is a gut problem of young Boxers that causes bloody diarrhea with mucus, and the right antibiotics usually clear it.

Lymphoma, a cancer of white blood cells, also runs in the breed.

Brain tumors mostly affect older Boxers, and a first seizure in a grown dog always needs a vet.

Eyes

Eyelids that droop (ectropion) or roll in (entropion) turn up in some Boxers, and a yearly eye exam finds them.

The American Boxer Club says Boxers seem prone to long-term kidney disease, and it pays for research on it.

Studies disagree on whether Boxers are prone to bone cancer (osteosarcoma).

Breathing

The short muzzle gives Boxers a mild risk of a blocked airway (BOAS), so skip hard exercise when it is hot.

Skin

White Boxers are more likely to be deaf in one or both ears, and their pale skin burns easily in strong sun.

The Boxer form of hemophilia A, an inherited bleeding problem, mostly affects males, and a DNA test can find it.

Boxer DNA tests

DNA tests

How it works

A cheek-swab DNA test works at any age and checks for a few inherited conditions in Boxers.

Possible results

Each result is clear (no copies of the gene change), carrier (one copy) or at risk (two copies).

Carrier result

A carrier is healthy.

At-risk result

An at-risk result means a higher chance, not a diagnosis. Among Boxers with degenerative myelopathy results sent to OFA, about 1 in 2 were at risk. This disease starts late, and many at-risk dogs never show signs. For your dog, an at-risk result is a reason to watch the hind legs in the senior years. Tests are also available for an ARVC marker, the Boxer form of hemophilia A and congenital macrothrombocytopenia. A positive ARVC marker shows a higher risk only, so the yearly Holter stays the main heart check.

Boxer vet checkups

Checkups your dog will get

Puppy visits
  • Your vet listens to the heart at the puppy visits, and any murmur is followed up with a heart scan.
  • For a white or mostly white puppy, ask about a hearing check.
  • Your own vet completes the puppy vaccine series.
Young adult
  • From 12 months, a yearly Holter checks the heart rhythm.
  • From 2 years, a thyroid blood test and hip and elbow X-rays show how the thyroid and joints are doing.
  • If a murmur was heard earlier, a heart scan around then is a good idea too.
Adult
  • Book a yearly exam that covers the heart, eyes, thyroid and skin.
  • A yearly eye check watches for corneal ulcers.
Senior
  • Older Boxers do best with an exam twice a year, with heart and lump checks and dental care.

Boxer Veterinary Health Report

What the Veterinary Health Report checks

What the exam covers →

The breeder's licensed vet checks your puppy before it goes home. The vet follows PetPay's exam standards, and the results go in your puppy's Veterinary Health Report.

  1. 1Puppies must be at least 8 weeks old and weigh at least 2 lb before they travel.
  2. 2If the vet finds something that could put your puppy at risk during travel, your puppy stays with the breeder until it's resolved.
  3. 3Problems that can be treated before travel are treated by the breeder's licensed vet first.
  4. 4Anything else the vet notes is shared with you.

Heart

What the vet checks

The vet listens to the heart for a murmur and notes its grade.

Boxer note

Soft, harmless murmurs are common in puppies and usually fade, while a narrowing present from birth (subaortic stenosis) may only be heard as the puppy grows. That is why your own vet keeps listening at the first visits.

Focus

Hearing (white puppies)

What the vet checks

For a white or mostly white puppy, the vet checks how it responds to sound.

Boxer note

White Boxers are more likely to be deaf in one or both ears.

Focus

Bite and teeth

What the vet checks

The vet checks the mouth, including that the lower canine teeth do not strike the roof of the mouth and that no baby teeth are retained.

Boxer note

An undershot bite is normal for the breed.

Honest limits

Puppies grow and change quickly, and their immune systems are still developing, so no exam can find everything. The Veterinary Health Report is a strong early look at your puppy and a written starting point that your own vet builds on.

Once your puppy is home
  • At the first visits with your own vet, have the heart listened to again, and follow up any murmur with a heart scan (echocardiogram).
  • Your puppy's vaccination and deworming records are separate documents that travel with your puppy.
  • Bring them, with the Veterinary Health Report, to your first visit so your vet starts from the same record.
  • Before travel, every puppy follows PetPay's vaccination and deworming schedule as far as its age allows.
  • Bordetella and corona are given at the vet's discretion, and no vaccine is given within 3 days of travel.
  • Rabies is given by a licensed vet on the schedule your state requires.
  • Your own vet completes the series.
  • Once your Boxer is grown, a yearly Holter, hip and elbow X-rays and a thyroid blood test show how the heart, joints and thyroid are doing.

Frequently asked questions about Boxer health

Frequently asked questions

The conditions that run in the breed include two heart problems (ARVC and subaortic stenosis), hip dysplasia, an underactive thyroid, the Boxer ulcer of the eye and degenerative myelopathy. Granulomatous colitis and several cancers, including mast cell tumors, lymphoma and brain tumors, are on the list too. A lean weight, a monthly skin check and a yearly exam that covers the heart help you stay ahead of them.

Some do, because Boxers are known to be prone to ARVC, a heart-rhythm disease of adults, and to subaortic stenosis, a narrowing present from birth. A yearly heart-rhythm recording (Holter) from about 12 months and a heart scan for any murmur help catch them early.

A murmur is not always a problem, because soft, harmless murmurs are common in puppies and usually fade. Because subaortic stenosis may only become audible as a puppy grows, a murmur is followed up with an echocardiogram, especially before surgery.

Cancer runs in the breed, including skin tumors called mast cell tumors, lymphoma and brain tumors. Boxers often get the lower-grade form of mast cell tumor, so a monthly skin check and sampling any new lump pay off.

It is a sore on the clear front of the eye that does not heal normally, and it usually appears in middle age. Vets call it SCCED (spontaneous chronic corneal epithelial defect). Squinting and tearing are the signs, and a vet usually treats it with a minor procedure.

Cheek-swab tests cover degenerative myelopathy, the Boxer form of the bleeding disorder hemophilia A, an ARVC risk marker and congenital macrothrombocytopenia. A carrier is healthy, and an at-risk result means a higher chance, not a diagnosis.

Degenerative myelopathy slowly weakens the hind legs, without pain, starting in middle or old age. A cheek-swab DNA test shows a puppy's risk, but an at-risk result is not a diagnosis, and many at-risk dogs never develop the disease.

Boxers typically live 10–12 years.

Book exams twice a year, with heart and lump checks and dental care. Watch the hind legs for dragging feet or wobbling, and treat a seizure or collapse as urgent.

Keep your Boxer lean, check the skin for lumps every month and book a yearly exam that covers the heart, eyes, thyroid and skin. Brush the teeth often, and keep your Boxer cool in hot weather.

White or mostly white Boxers burn easily, so keep them out of strong sun. They are also more likely to be deaf, so ask your vet about a hearing check.
