Dog Nutrition: Feeding for Lifelong Welfare

Nutrition is foundational to dog health and welfare across all life stages. Understanding key principles helps owners make welfare-positive feeding decisions.

Key Facts

Dogs are omnivores capable of thriving on a range of diets when nutritional requirements are met
Life stage-appropriate feeding (puppy, adult, senior) is important — nutritional requirements change significantly
Obesity is the most common nutritional welfare problem — affecting 40-50% of adult dogs
Grain-free diets have been associated with dilated cardiomyopathy in some breeds — veterinary guidance is important
Raw diets carry bacterial contamination risks to dogs and humans — food safety must be carefully managed
AAFCO or equivalent nutritional adequacy statements indicate diets have met minimum requirements
Water is the single most important dietary component — constant access is non-negotiable

Welfare Considerations

Dog nutrition underpins welfare across a dog's entire lifespan. Puppies fed inadequately during growth develop skeletal and immune problems; adult dogs fed too much become obese with the associated joint, cardiovascular, and metabolic welfare impacts; senior dogs have changing nutritional requirements that standard adult diets may not meet. The diversity of available diets — from dry kibble to raw to home-prepared — creates both choice and confusion. Veterinary nutritional guidance is underutilised for most dogs despite the fundamental importance of nutrition to health. The most important welfare-protective feeding principles are simple: maintain healthy body weight throughout life, feed life-stage appropriate food that meets AAFCO standards, and ensure constant water access.

What You Can Do

Maintain a healthy body weight throughout your dog's life — obesity is the most common preventable welfare problem
Feed life-stage appropriate food that meets minimum nutritional standards
Consult your vet about nutrition, particularly for dogs with health conditions, growth stages, or unusual diet choices
Provide constant access to fresh water — hydration is the single most important dietary element
Be cautious of diet trends; base feeding decisions on veterinary evidence rather than marketing
