As a pet nutrition expert, I recommend a balanced diet tailored to your pet’s species, age, size, and health needs. For dogs and cats, choose high-quality commercial foods with named protein sources (e.g., chicken, beef) as the first ingredient. Ensure the diet meets AAFCO standards. Include fresh water daily, and avoid feeding human foods like chocolate, grapes, or onions, which are toxic. For specific conditions (e.g., obesity, allergies), consult a vet for specialized diets. Portion control is key—follow feeding guidelines and adjust based on activity level. Treats should be less than 10% of daily calories. For exotic pets, research species-specific needs. Always monitor weight and health.
