Understanding your dog's life stages helps you provide appropriate care, nutrition, and activities at each phase. From the rapid development of puppyhood to the special needs of senior dogs, each stage brings unique joys and challenges.
Puppyhood (0-12 months)
Key Characteristics:

Bringing Your New Dog Home - First 24 Hours
Whether you have a puppy or adult dog, the first day sets the tone for your relationship:
Before Arrival:
- Dog-proof your home (remove hazards, secure trash)

- Place bed near your bedroom for comfort
- Expect some whining or restlessness
- Take out for last toilet break before bed
- Be prepared for night-time toilet needs (especially puppies)
End-of-Life Planning
This difficult topic is an important part of responsible dog ownership:
Quality of Life Considerations:
- Can they eat, drink, and toilet normally?
- Are they mobile and comfortable?
- Do they show interest in family and activities?
- Are they experiencing more bad days than good?
- Can pain be managed effectively?
Making Difficult Decisions:
- Discuss quality of life honestly with your vet
- Consider your dog's personality and preferences
- Plan for peaceful passing at home or clinic
- Allow family members to say goodbye
- Decide on cremation or burial arrangements
Life Stage Tips
- Adapt your expectations to your dog's current life stage
- Regular vet check-ups become more important with age
- Take lots of photos and videos - time passes quickly
- Enjoy the unique characteristics of each stage
- Senior dogs can still learn and enjoy new experiences
- Every dog ages differently - follow their individual needs
Frequently Asked Questions
Most dogs should transition to adult food around 12 months of age. Large and giant breeds may need to stay on puppy food until 18-24 months as they continue growing. Transition gradually over 7-10 days by mixing increasing amounts of adult food with decreasing amounts of puppy food. Consult your vet for breed-specific timing.
Puppies need short, frequent play sessions (5 minutes per month of age, twice daily). Adolescents can handle 30-60 minutes daily. Adults typically need 1-2 hours depending on breed. Seniors benefit from shorter, gentler walks (20-30 minutes) with rest breaks. Always adjust based on your individual dog's fitness level and health status.
Signs include: slowing down on walks, sleeping more, grey hairs (especially around muzzle), stiffness when getting up, reduced interest in play, changes in appetite, confusion or disorientation, and difficulty with stairs or jumping. These changes typically begin around 7 years for most dogs, earlier for larger breeds.
Traditional advice was 6 months, but current research suggests waiting until after first heat for females (12-15 months) and 12-18 months for males, especially in large breeds. This allows for proper bone and joint development. Discuss the best timing with your vet based on your dog's breed, size, and individual circumstances.
Neutering your dog is also the responsible thing to do.
Stay consistent with training, increase mental stimulation and physical exercise, be patient with regression in behaviours, continue socialisation, provide appropriate outlets for energy (puzzle toys, training), and remember this phase is temporary. Avoid punishment-based training as adolescent dogs can become fearful or aggressive. Positive reinforcement works best.
Senior dogs benefit from: twice-yearly vet visits instead of annual, senior-specific food with joint support, gentler exercise routines, orthopedic bedding, consistent routines to reduce anxiety, more frequent potty breaks, and management of any chronic conditions. Watch for cognitive changes and adapt their environment for safety and comfort.
The critical socialisation period is from 3-14 weeks of age, when puppies are most receptive to new experiences. During this time, expose them to various people, animals, environments, sounds, and surfaces. After 14 weeks, socialisation becomes more difficult but should continue throughout life. Puppy classes are excellent for safe, controlled socialisation.
Signs of pain in senior dogs include: reluctance to move or exercise, difficulty getting up or lying down, changes in appetite, excessive panting, restlessness, whimpering, aggression when touched, changes in bathroom habits, and reduced interest in activities they once enjoyed. Dogs often hide pain, so subtle changes in behaviour are important to notice and discuss with your vet.
