Feeding Your Dog or Cat Well
Choose a complete, life-stage-appropriate diet, measure portions to body condition, and adjust with your vet rather than by the bag alone.

Good feeding is less about a single perfect food and more about a complete, appropriate diet fed in the right amount. Matching food to life stage, measuring portions, watching body condition, and consulting your vet keep a pet at a healthy weight.
What it is
Feeding well is one of the biggest levers owners have over a pet's long-term health, and it is more about consistency and portion than about chasing a perfect product.
Choose a complete, appropriate diet. Look for food labelled as complete and balanced for your pet's life stage (for example puppy/kitten, adult, or senior), meaning it provides the nutrients that species needs. A crucial species difference: cats are obligate carnivores with specific requirements (such as taurine) and must not be fed as if they were dogs or, especially, as vegetarians.
Feed the right amount. Feeding guidelines on packaging are starting points, not prescriptions — they are often generous. Measure meals rather than eyeballing them, and adjust based on your individual pet's body condition and activity, not the bag alone.
Use body condition, not just the scale. Learn to assess body-condition score: you should be able to feel the ribs easily, see a waist from above, and see a tummy tuck from the side. Overfeeding and excess treats are a leading cause of pet obesity, which harms long-term health.
Handle treats and changes sensibly. Keep treats to a small fraction of daily calories. When switching foods, transition gradually over several days to avoid stomach upset. Provide fresh water at all times.
Watch for special needs. Puppies and kittens, pregnant or nursing animals, seniors, and pets with medical conditions have different needs. Some foods and human items are toxic to pets, so check before sharing.
Because the right diet and amount depend on the individual animal's age, weight, health, and lifestyle, use this as general guidance and confirm a feeding plan with your veterinarian.
Worked example
An owner notices their dog is looking round. Instead of guessing, they weigh the food with a measuring cup, cut treats back to a small share of daily calories, learn to feel for the ribs and check for a waist, and ask the vet to confirm a target body condition and a portion to reach it gradually.
