Companion Animal Nutrition and Welfare

Nutrition is foundational to companion animal welfare — both undernutrition and overnutrition cause disease, and the pet food market's complexity makes informed feeding decisions challenging for most owners.

Key Facts

Obesity affects 50-60% of dogs and cats in developed countries and is the most common nutrition-related welfare problem
Nutritional deficiencies from unbalanced homemade diets or inappropriate commercial foods cause preventable health problems
Cats are obligate carnivores requiring taurine, arachidonic acid, and preformed vitamin A from animal sources
Raw food diets carry bacterial contamination risks (Salmonella, E. coli) for both pets and human household members
AAFCO (US) and FEDIAF (EU) standards define nutritional adequacy for pet food — look for these certifications
Grain-free diets have been associated with dilated cardiomyopathy in dogs in an ongoing FDA investigation
Senior animals have different nutritional requirements that many standard formulations do not address adequately
Food puzzles and slow feeders address both obesity prevention and behavioural enrichment simultaneously

Welfare Considerations

Companion animal nutrition welfare sits at the intersection of owner knowledge, industry marketing, and veterinary guidance that is not always aligned. The pet food market is vast and not always regulated at standards that ensure optimal animal welfare outcomes. The obesity epidemic in companion animals reflects both dietary overabundance and insufficient exercise — a welfare problem almost entirely within owner control. Nutritional deficiencies from poorly formulated diets can cause severe disease that unfolds over months before clinical signs appear. Veterinary nutritional guidance is the most reliable resource, but is underutilised partly because owners feel confident in making food choices independently and are targeted by marketing claims that may not reflect nutritional science.

What You Can Do

Feed measured portions using a scale and consult your vet about appropriate caloric intake for your animal's age, weight, and activity level
Choose foods meeting AAFCO or FEDIAF complete and balanced standards rather than relying on marketing claims
Discuss any homemade or raw food diet with a veterinary nutritionist before implementing to ensure nutritional adequacy
Use food puzzles and interactive feeders to slow eating and provide mental enrichment alongside nutritional support
