Your Puppy at 6 to 9 Months: A Practical Guide to Early Adolescence

By Dr Duncan Houston

Your puppy used to come when called. Now a blowing leaf seems more interesting than you, and the shoes are suddenly back on the menu. Between six and nine months, growing confidence and changing responses can make familiar routines feel less reliable. The helpful question is what your puppy needs to succeed today.

Quick Answer

At six to nine months, puppies still need growth-appropriate nutrition, supervised exercise, plenty of rest and reward-based practice. Return to easier training situations when skills slip, and manage access to hazards while those skills develop. Sudden fear, house-soiling, lameness or a marked change in appetite deserves a veterinary assessment rather than being dismissed as adolescence.

What development looks like now

Size and maturity do not move in lockstep. A small puppy may be approaching adult size while a large puppy has substantial growth ahead. Neither appearance nor a birthday confirms that growth plates have closed. Keep repetitive jumping, forced distance running and strenuous sport off the programme until your veterinarian has assessed readiness.

Adult teeth are usually emerging or established by this stage, but two teeth sharing one position, a painful mouth or difficulty eating should be checked. Chewing also serves exploration and relaxation; it does not disappear automatically when teething ends.

Sexual maturity can arrive before physical or emotional maturity. Prevent unplanned breeding with secure separation and supervision, and discuss reproductive care for your individual dog. Neutering is not a guaranteed treatment for barking, fear or every form of urine marking.

Reset three everyday skills

Recall

Use a secure fenced area or a long line attached to a well-fitting harness. Practise at a distance and distraction level where your puppy can respond. Say the cue once, reward generously when they reach you, then often release them to explore again. Calling repeatedly while the puppy runs away rehearses the wrong pattern. Never punish a return, however long it took.

Toilet training

Temporarily return to supervised access, frequent outdoor opportunities and rewards immediately after toileting in the right place. Note whether accidents follow excitement, longer gaps, drinking or being left alone. Straining, blood, excessive thirst, tiny frequent urinations or accidents during sleep need a medical conversation.

Chewing and taking objects

Put laundry, rubbish and unsafe objects behind closed doors. Offer appropriate chews with supervision and practise trading low-value objects for food. Chasing your puppy can turn retrieval into a game or encourage swallowing. Suspected swallowed batteries, medicines, string or other dangerous objects requires urgent veterinary advice.

Cornell's advice on adolescent puppy-proofing explains why management still matters after the tiny-puppy stage.

Make the day easier to predict

Build a sequence that fits your household: toilet break, meal, short activity, quiet rest, then another toilet opportunity. A sniffing walk and a brief food-search game may suit your puppy better than constant high-energy play. Practise settling on a mat while you read or prepare dinner, rewarding relaxed behaviour before demanding long periods of stillness.

Increase difficulty one step at a time. If your puppy can wait at an open bedroom door, the busy front doorway may still be too challenging. If they settle while you are beside them, practise a brief step away before expecting independent rest in another room.

Record one small success each day. A calmer recovery after seeing a dog, a voluntary check-in or a quiet minute during dinner gives you useful information about progress.

Keep social experiences comfortable

Your puppy does not need to greet everyone. Watch for loose movement and a willingness to approach, and allow distance when they freeze, turn away, tuck their tail or repeatedly try to leave. Choose quieter places and compatible dogs, and interrupt play for breaks.

New fear calls for easier experiences, not forced exposure. The AAHA behaviour guidelines recommend reviewing behaviour during development. Seek help early for persistent distress, guarding or escalating reactions; a medical examination and qualified reward-based behaviour support can work together.

Check food and preventive care

• Food: Continue a complete diet suitable for growth until the appropriate transition. Large-breed puppies need a formulation suitable for their expected adult size.
• Portions: Track actual weight and body condition. Include training rewards in the food budget instead of adding them on top of full meals.
• Vaccines: Check the recorded dates and planned follow-up. Age alone does not prove that a course is complete.
• Parasite prevention: Confirm that the product and weight band still fit your growing puppy.
• Handling: Practise brief, rewarded tooth brushing, paw handling and grooming without wrestling.

The AAHA canine life-stage checklist provides a useful structure for this review.

When a change needs care

Arrange a prompt examination for persistent limping, reduced appetite, repeated diarrhoea, new house-soiling or unusual sensitivity to touch. Collapse, difficulty breathing, seizures, repeated unproductive retching or suspected poisoning needs urgent in-person care. A puppy's age does not make these problems normal.

Frequently Asked Questions

Has my puppy forgotten their training?

Often the setting has become more difficult or exciting. Lower the distraction level, reward success and rebuild gradually. A sudden widespread change also warrants a health check.

Should I exercise them until they are exhausted?

No. Alternate suitable activity with rest and quiet enrichment. More stimulation can make an overtired puppy less able to settle.

Is six months the deadline for spaying or neutering?

No universal deadline suits every dog. Discuss sex, breed, health, household management and reproductive risk with your veterinarian.

Should every walk include a dog greeting?

No. Calmly passing at a comfortable distance is an equally useful social skill.
