Feeding Your Dog or Cat Right, at Every Life Stage

Nutrition needs change more across a pet's life than most owners realize. Feeding an adult-formula diet to a growing puppy, or an energy-dense puppy diet to a sedentary senior, are two of the most common — and most avoidable — nutrition mistakes.

Puppies & Kittens (0–12 months)

Growth requires significantly more protein, calories, and calcium/phosphorus (in the right ratio) than adult maintenance. Large-breed puppies in particular need growth-controlled formulas — overfeeding calories and calcium during this stage is linked to joint problems later in life.

Adults (1–7 years, varies by breed size)

The priority shifts to maintaining a healthy weight rather than growth. Body condition — being able to feel (not see) the ribs, with a visible waist from above — is a better guide than following bag instructions exactly, since activity level varies enormously between pets.

Seniors

Metabolism typically slows, and joint, kidney, or dental issues become more common — softer food, adjusted calorie intake, and joint-support supplements are worth discussing with your vet. Senior pets also benefit from more frequent checkups to catch weight and organ-function changes early.

Signs Your Pet's Diet Isn't Working

• Noticeable weight gain or loss over a few weeks
• Dull coat, excessive shedding, or flaky skin
• Low energy that isn't explained by age alone
• Frequent digestive upset after meals

If you notice any of these, it's worth a checkup rather than switching foods repeatedly on your own — some of these signs overlap with medical conditions that diet alone won't fix.
