How Much Does Breed Affect Dog Behaviour and Training?

By Dr Duncan Houston

A retriever who ignores tennis balls and a terrier who loves a quiet afternoon are not reading the breed manual incorrectly. Breed descriptions describe tendencies across groups, with plenty of variation between individual dogs.

The useful question is what your dog enjoys, what worries them and what helps them learn.

Quick Answer

Breed and ancestry can influence behaviours such as chasing, retrieving and herding, but they do not determine an individual dog’s temperament. Health, development, learning and surroundings also matter. Use reward-based training and judge safety from the dog’s behaviour and history, rather than their breed label.

What can breed tell you?

Selective breeding has encouraged particular working abilities and physical traits. A dog bred for tracking may find smells especially rewarding; one from herding lines may notice movement quickly. These are starting points for observation, not promises about every puppy.

A UMass Chan genetic study found that breed explained only a modest part of individual behavioural variation. This does not mean genetics are irrelevant. It means breed alone is a poor personality test.

Match the activity to the dog in front of you

• A dog who loves sniffing may enjoy finding scattered food or following a simple scent trail.
• A keen retriever may enjoy short, controlled retrieves, with breaks before they become exhausted.
• A dog who digs can have an appropriate digging area with supervision.
• A watchful dog may need distance from busy boundaries, predictable routines and rewarded calm responses.

Small dogs need enrichment too. Flat-faced dogs who tire or breathe noisily should not have those signs dismissed as laziness or a normal breed personality.

When does behaviour need more help?

What else could explain the problem?

Before blaming ancestry, consider pain, itch, poor sleep, fear, frustration, limited toilet access or an exercise routine that is too demanding. A previously relaxed dog who suddenly objects to touch needs a health assessment. Training cannot remove an untreated medical cause.

A practical training plan

1. Choose one observable goal, such as turning towards you when called indoors.
2. Identify a reward your dog actually wants: food, play or access to sniffing.
3. Practise in short sessions where distractions are manageable.
4. Increase difficulty gradually and reward successful responses promptly.
5. Record the setting and response. If the dog becomes tense or stops engaging, make the task easier.

Keep children and other animals safely separated when chasing, guarding or biting is possible. Do not stage a confrontation to test temperament.

Common mistakes

• Calling a dog stubborn when they are frightened, sore or confused.
• Assuming a familiar breed is automatically safe with children.
• Trying to exhaust a high-energy dog without teaching rest.
• Using punishment to suppress warnings such as growling.

Build habits that support behaviour

Combine comfortable exercise, sleep, sniffing, predictable meals and gentle exposure to new experiences at the dog’s pace. The RSPCA body-language guide helps identify when a dog needs more space.

Frequently Asked Questions

Can a DNA test tell me how to train my dog?

It can provide ancestry information, but observation and reward-based teaching are more useful for choosing daily training steps.

Are mixed-breed dogs unpredictable?

All dogs have individual variation. Known history and behaviour across ordinary situations are more informative than appearance alone.

Do working breeds need hours of running?

Needs vary with age, health and conditioning. Mental activity and learning to relax matter alongside exercise.

Let breed knowledge inform your questions, then let your dog’s actual responses guide the plan.
