Desexing Boxers: Why We Recommend Waiting Until 18–24 Months
Unlike many breeders, we do not desex our puppies before they go home. This is a deliberate choice backed by science — here's why we strongly recommend waiting until your Boxer is 18–24 months old.
🔬 What the research says: A landmark study by UC Davis found that large-breed dogs desexed before one year face significantly higher risks of joint disorders including hip dysplasia, elbow dysplasia, and cranial cruciate ligament tears. For dogs exceeding 20kg as adults, the risk was several times higher than in intact dogs.
Why Boxers Specifically Need to Wait
Boxers are a large, athletic breed — they're built for agility, speed, and power. Their long-term mobility depends entirely on proper skeletal development in those crucial early years.
✓ Waiting Until 18–24 Months
- Joints and bones fully develop under natural hormone influence
- Growth plates close properly
- Muscle mass develops correctly
- Lower risk of orthopaedic issues later in life
- Better weight management long-term
✗ Early Desexing (Before 12 Months)
- Growth plates may close late or unevenly
- Increased risk of hip/elbow dysplasia
- Higher likelihood of CCL injuries
- Can affect bone density
- May contribute to weight gain issues
The Science Simplified
Sex hormones (oestrogen and testosterone) play a crucial role in skeletal development. They signal growth plates when to close — and when that signal is missing (because of early desexing), bones can continue growing abnormally. For a breed like the Boxer, whose athleticism depends on perfectly formed joints, this matters enormously.
Managing an Intact Dog
We understand that waiting means managing an intact dog, which requires some extra responsibility. Here's what to expect:
- Female seasons: Typically occur every 6–7 months. You'll need to manage carefully during her cycle (roughly 3 weeks).
- Male behaviour: May show interest in females in season. Standard leash manners and supervision apply.
- No roaming: Intact dogs can be more motivated to wander. Secure fencing and leash walks are essential.
- Socialisation continues normally: Being intact doesn't affect temperament, trainability, or ability to socialise safely.
Making the Decision
Ultimately, desexing timing is a conversation between you and your vet. Factors like your individual dog's development, your lifestyle, and local regulations all play a part. What we want is for you to make an informed decision — and now you have the information to do exactly that.
Our commitment: Whether you desex at 18 months, 24 months, or choose a different path altogether, we support your decision. We're here to discuss it, help you find a vet who understands large-breed needs, and provide guidance whenever you need it. Your Boxer's health is — and always will be — our priority.
