From Puppy to Senior: How Your Dog’s Nutritional Needs Change Over Time

From Puppy to Senior: How Your Dog’s Nutritional Needs Change Over Time

Just like humans, dogs have evolving nutritional needs as they age. A growing puppy, a playful adult, and a wise senior all require different types and levels of support to stay healthy and happy. At Petrition, we believe in proactive, holistic care — and that starts with understanding what your dog’s body needs at every stage of life.

Puppy Stage (0–12 months): Growth & Development

Puppies grow rapidly and require a nutrient-rich diet to support the development of their bones, muscles, brain, and immune system. Key nutrients include:

  • High-quality protein for tissue development

  • Omega-3 fatty acids (like DHA) for brain and eye development

  • Calcium and phosphorus for healthy bone growth

  • Probiotics to help establish a strong digestive and immune foundation

💡 Petrition Tip: Start with a probiotic supplement early to support gut health — this helps reduce digestive upsets common during the weaning phase and supports immunity during vaccinations.


Adult Dogs (1–7 years): Maintenance & Performance

Once your dog reaches adulthood, the focus shifts to maintaining energy, supporting digestion, and preventing common health issues. Adult dogs need:

  • Balanced protein and fat levels for energy

  • Joint support nutrients (like glucosamine and MSM) for active dogs

  • Fibre and probiotics for regular digestion

  • Antioxidants to protect against cellular damage

💡 Petrition Tip: Adult dogs benefit from daily multivitamin chews to fill any nutritional gaps and support overall vitality.


Senior Dogs (7+ years): Support & Prevention

As dogs age, their metabolism slows and health issues may arise — such as arthritis, cognitive decline, and reduced immune function. Senior dogs need:

  • Lower calories, higher fibre to manage weight

  • Glucosamine, chondroitin, and MSM for joint mobility

  • Omega-3 fatty acids for inflammation and brain health

  • Probiotics and digestive enzymes to help absorb nutrients more efficiently

💡 Petrition Tip: Our Senior Support Chews are formulated to promote joint comfort, cognitive health, and digestive balance — everything your older dog needs in one daily treat.


Tailoring Supplements to Life Stages

At Petrition, we craft our supplements with life stage in mind. Whether it’s our Probiotics for puppies and adults, Hip & Joint Support for active or older dogs, or our Senior Chews for ageing pets — we’re here to help you support your dog through every chapter of life.

Because no matter their age, they deserve to feel their best — every single day.
