Feeding Your Pet at Every Life Stage

betrbowl · Pet Health Education

What your pet needs from their food changes as they age — sometimes in ways that aren't obvious. A puppy and a senior dog may look like the same species, but nutritionally they're in very different places. Here's a practical guide to what matters most at each stage of life.

Dogs

Puppies

Puppies are building everything at once — bones, muscles, organs, immune systems, brains. Their nutritional demands are higher than at any other life stage.

• Look for higher protein (28–32%) to support muscle and tissue development.
• DHA — an omega-3 fatty acid found in fish oil — supports healthy brain and eye development during the critical early months.
• Feed three meals a day until around six months, then transition to twice daily.
• Large and giant breed puppies need special attention: too much calcium and protein too fast causes bones and joints to grow too quickly, leading to structural problems. Look for formulas specifically designed for large breed puppies.

Adult Dogs

Adult dogs need maintenance nutrition — enough protein to sustain muscle mass, balanced fat for energy and coat health, and the right carbohydrate level for their activity level.

• Twice daily feeding works well for most adult dogs.
• Active dogs can handle moderate carbohydrate levels. Less active or overweight dogs do better with lower carb, higher protein formulas.
• This is the ideal stage to establish a rotation habit — varying proteins and formats builds a more resilient digestive system over time.

Senior Dogs

Senior dogs — generally 7 years and up for smaller breeds, 5 and up for large breeds — face slower metabolism, reduced digestive efficiency, and higher risk of joint and dental disease.

• Protein remains important — don't reduce it dramatically. Senior dogs need it to maintain muscle mass.
• Joint support becomes a priority: glucosamine, chondroitin, and omega-3 fatty acids help maintain mobility and reduce inflammation.
• Higher moisture diets support kidney function.
• Digestive enzymes and probiotics help compensate for reduced digestive efficiency.

Cats

Kittens

Kittens are obligate carnivores in rapid growth — they need dense, meat-based nutrition from the start.

• High-protein wet food or raw as a primary diet — kittens need moisture and animal protein in abundance.
• Taurine is non-negotiable at every life stage.
• Three to four small meals daily works better than two large ones.
• Introduce variety early. Cats who eat a variety of proteins and formats as kittens are much easier to feed as adults.

Adult Cats

Adult cats need low-carbohydrate, high-moisture, high-protein diets — and most don't get them. Over 50% of domestic cats are overweight, and diet is the primary reason.

• Wet food, raw, or freeze-dried as a primary diet. High moisture is the single most impactful factor for long-term kidney and urinary health.
• Dry food alone is not an ideal long-term diet for cats, no matter the quality. The moisture deficit adds up over years.
• If your cat only eats dry food, adding water or broth to the bowl and transitioning gradually toward wet food is worthwhile.

Senior Cats

Senior cats — generally 10 years and older — are at elevated risk for kidney disease, hyperthyroidism, and muscle loss.

• High moisture is more critical than ever. Wet food or raw should be the foundation.
• Lower phosphorus helps protect aging kidneys.
• Digestive enzymes and antioxidants support both absorption and cellular health.
• Some senior cats lose weight despite eating well — this is worth a vet check, as it often points to hyperthyroidism or early kidney disease.
