Pet Nutrition Basics for Dogs & Cats

Good nutrition is the foundation of your pet's health — coat, energy, weight, and even behavior all trace back to the food bowl.

Choosing a Food

Look for a "complete and balanced" statement (e.g., AAFCO) appropriate to your pet's life stage: puppy/kitten, adult, or senior. Dogs are omnivores; cats are obligate carnivores and need meat-based diets with taurine.

Portion Control

Feeding guides on the bag are starting points, not rules. Adjust for your pet's body condition: you should feel ribs easily but not see them prominently. Measure meals with an actual measuring cup — "eyeballing" is the top cause of pet obesity.

Feeding Schedules

• Puppies: 3–4 meals daily, tapering to 2 by adulthood.
• Kittens: 3–4 small meals, or measured portions several times daily.
• Adult dogs and cats: 2 meals daily works well for most.

Foods to Never Feed

Chocolate, grapes and raisins, onions and garlic, xylitol (in sugar-free products), alcohol, cooked bones, and for cats, dog food as a staple. When in doubt, don't share.

Treats & Extras

Keep treats under 10% of daily calories. Use part of the daily kibble ration for training treats to avoid calorie creep.

Reading a Pet Food Label

Three things matter far more than marketing words like "premium" or "natural":

1. The nutritional adequacy statement — look for "complete and balanced for [life stage] based on AAFCO nutrient profiles (or feeding trials)."
2. Life stage match — growth (puppy/kitten), adult maintenance, or all-life-stages. Seniors often do well on adult formulas adjusted for calories.
3. Calories per cup/can — the number you actually need for portion math. Two foods can differ by 200 kcal per cup.

Ingredient lists are the least useful part of the label: ingredients are ranked by weight including water, so "fresh chicken first" is often a moisture artifact, not a quality signal.

Weight Management: The Body Condition Check

Weight is the single most controllable factor in your pet's lifespan — studies in dogs show lean-fed dogs living meaningfully longer. Monthly, do the three-point check:

• Ribs: easily felt with flat hands, not seen (except sighthounds).
• Waist: visible tuck behind the ribs from above.
• Belly: rises toward the hips from the side, no swinging pouch (cats: a small primordial pouch is normal).

Trending heavy? Cut portions by ~10%, weigh weekly, and convert one meal's worth of kibble into training treats instead of adding extras. See our senior care guide for age-related adjustments.

Common Nutrition Myths

• "Grain-free is healthier." Grains are well digested by most pets; grain-free became a fashion, and some grain-free diets were investigated in connection with heart disease in dogs. Choose evidence over trend.
• "By-products are bad." By-products include organ meats — often more nutritious than muscle meat. Vague labeling is a fair criticism; the category itself isn't.
• "Cats should drink milk." Most adult cats are lactose intolerant. Water only.
• "Table scraps are fine in small amounts." Some are (plain cooked chicken, green beans); many aren't (anything fatty, seasoned, or on the toxic list). Fatty scraps are a classic pancreatitis trigger in dogs.

Signs of a Diet Problem

Dull coat, chronic itching, loose stools, weight change, or low energy can be diet-related — but always rule out medical causes with your vet before switching foods repeatedly.
