If your dog or cat had its way, you’d share everything you ate with it at every meal. Those big eyes can be persuasive, but pets don’t actually know what’s good for them — and cats and dogs have very different nutritional needs than humans. While an occasional small treat won’t hurt, proper nutrition is what keeps your pet healthy and energetic long-term.

Pet Nutritional Requirements by Age

Just as you wouldn’t feed a steak dinner to a baby, you shouldn’t feed your kitten or puppy the same food you’d give a full-grown dog or cat. Nutritional needs shift as pets age, starting with their first meals after weaning. Most kitten and puppy formulas contain higher levels of fat, protein, and calcium to support rapid growth during the first six months of life. You can feed a life-stage-specific formula, or choose food labeled “complete and balanced for all life stages.” Our veterinarians can advise on how much to feed your new pet to support healthy growth without overfeeding, which can lead to stomach upset and, eventually, obesity.

Once your pet reaches one year of age, it’s time to transition to adult food. Read nutrition labels carefully to confirm the formula supports a complete diet. Cats need roughly twice the protein of dogs or humans, pound for pound, and it needs to come from fish or meat. Dogs, by contrast, thrive on a broader variety of nutrients, including those from vegetables and some grains.

Cats and dogs over ten years of age are generally considered seniors. Once your pet reaches this stage, talk with our veterinarians about adjusting their diet — see our senior pet care page for more. Senior pets naturally slow down and burn fewer calories, while some don’t absorb nutrients as efficiently, which can lead to unexpected weight loss.

If you’re weighing raw or grain-free diet trends for your pet, our raw and grain-free diets page covers what to know before making the switch. And if your pet is dealing with a skin issue that might be diet-related, our pet dermatology team can help pinpoint the cause.

Frequently Asked Questions About Pet Nutrition

When should I switch my puppy or kitten to adult food?

Most pets can transition to adult food around one year of age, though larger dog breeds may need puppy formula a bit longer.

How do I know if my pet’s food is nutritionally complete?

Look for a label stating the food is “complete and balanced” for your pet’s life stage, and ask your veterinarian if you have questions about a specific brand.

Do senior pets need a different diet?

Yes. Senior pets often need more digestible food and fewer calories, since metabolism slows with age.

Can diet changes help with my pet’s skin or coat issues?

Often, yes. Food sensitivities are a common cause of skin problems, and our dermatology team can help identify whether diet is a factor.

Is human food ever safe to share with my pet?

Small amounts of certain foods are generally fine, but many common human foods are unsafe for pets. Ask your veterinarian before sharing anything new.

How much should I feed my pet each day?

Feeding amounts depend on your pet’s age, weight, activity level, and food type. Your veterinarian can give you specific guidance at your next visit.

Should I be concerned about my pet gaining or losing weight?

Any noticeable weight change is worth discussing at your next wellness exam, since it can signal a dietary or health issue.
