πŸ“ Summary

A dog's nutritional needs shift from puppyhood to old age, and portion sizes vary by breed size and maturity timeline. Feed age-appropriate food, build steady habits, and switch to vet-prescribed diets for senior conditions like diabetes or joint disease.

1 Feeding Dogs Through Every Life Stage

1. Life Stages Differ by Breed Size

Small breeds under 10 kg

Chihuahuas, Schnauzers, Yorkies, and Miniature Poodles mature at 8–10 months and reach old age around 8 years. Small breeds live longest, averaging 15–19 years.

Medium breeds 10–25 kg

Cockers, Spaniels, and Border Collies mature at 12–15 months and enter old age near 8 years.

Large breeds 25–45 kg

German Shepherds, Goldens, and Labradors mature at 15–18 months and live 8–9 years.

Giant breeds over 45 kg

Saint Bernards, Tibetan Mastiffs, and Bernese Mountain Dogs mature at 18–24 months and average 8–9 years.

2. Nutritional Needs by Stage

Nursing to 3 months

From about 2 months, puppies can start kibble β€” soak puppy growth pΓ’tΓ© in warm water to meet this stage’s needs.

Puppy stage, 3–6 months

Rapid bone and body growth raises protein and calcium needs; set regular meal times, control portions, and avoid overfeeding.

Adolescence, before 1 year

Hormonal swings need rich, complete nutrition β€” protein, fat, carbs, calcium, iron, and vitamins all matter.

Adult, 1–7 years

Active adults eat more; adjust portions and frequency to condition, and keep people food out of the bowl for a healthy diet.

Senior, 7+ years

Aging brings declining function; for conditions like diabetes or joint disease, follow the vet’s prescription diet rather than random supplements, and schedule regular checkups.

A dog’s life is only a dozen-odd years, given wholly to its owner. It’s the first to greet you at the door β€” if you don’t care for it, who will?

Match the bowl to the dog’s age and size, and let your vet guide senior dietary changes.
