Nutrition for Puppies and Kittens

Feeding your puppy or kitten can feel overwhelming, especially with so many choices on the market. However, getting your pet’s nutrition right from the start is one of the best things you can do to support their long-term health, growth, and development. Puppies and kittens grow rapidly in their first year, and their dietary needs are very different from those of adult pets. At Forth Valley Vet Clinic, we’re here to help you choose a balanced, appropriate diet that suits your pet’s breed, size, life stage, and lifestyle. 

Nutrition Matters

WHY GOOD NUTRITION MATTERS

Nutrition affects every part of your pet’s body, from their bones, joints, and muscles to their skin, coat, teeth, and immune system. Feeding a high-quality, complete and balanced diet gives your pet the essential nutrients they need to grow strong and thrive.

Poor nutrition can lead to:

  • Weak bones and joints

  • Poor growth and development

  • Digestive issues

  • Dull coat and itchy skin

  • Obesity or underweight

  • Long-term health problems in adulthood

WHAT SHOULD I FEED MY PUPPY OR KITTEN?

We recommend feeding a premium veterinary diet specially formulated for puppies or kittens. Brands like Hill’s Science Diet, Royal Canin, and Eukanuba are scientifically backed, highly digestible, and nutritionally complete.

These diets:

  1. Contain high-quality proteins and balanced amino acids

  2. Are free from unnecessary fillers, artificial colours, soy

  3. Have the right calcium-phosphorus ratio for healthy bone growth

  4. Support skin, coat, gut health, and immune function

  5. Are available in wet and dry formats to suit your pet's preferences and provide a recommendation for feeding amounts

What About Supermarket or Home-Cooked Foods?

Supermarket pet foods often meet basic nutrition standards but can contain cheaper ingredients (like offal, cereals, or soy) that reduce digestibility and lead to flatulence, odorous stools, or poor skin condition. Quality pet foods are predominantly sold in pet stores and vets rather than supermarkets. Quality food is more about the ingredients than the price tag so read the label carefully.

Raw or home-prepared diets can seem like a natural option, but they come with significant risks, especially for growing puppies. Home-cooked meals are rarely nutritionally complete unless designed by a veterinary nutritionist. Even small imbalances in calcium, phosphorus, or essential fatty acids can lead to developmental issues, bone deformities, or skin conditions in growing pups.

Raw meat diets may offer benefits like shinier coats or smaller stools, but they must be carefully balanced and handled hygienically. Risks include bacterial contamination (salmonella, E. coli), choking on bones, and long-term nutrient deficiencies.

If you’re considering a home-prepared or raw diet, speak with us first. We can help you decide if it’s suitable for your puppy and whether a veterinary-formulated raw or fresh food alternative might be safer.

PUPPY AND KITTEN FEEDING GUIDELINES


TRANSITIONING YOUR PUPPY TO A NEW FOOD

When you bring your puppy home from the breeder, it’s likely they’ve been eating a specific brand or type of food. While you might prefer to feed a different diet—such as a premium veterinary-recommended option—it’s important to transition gradually to avoid upsetting their sensitive digestive system.

Sudden changes in diet can lead to:

  • Soft stools or diarrhoea

  • Vomiting

  • Loss of appetite

  • Tummy discomfort

Start the transition once your puppy has settled in, usually after 3–5 days. A slow change over 7–10 days is ideal. During the transition always monitor your puppy’s stool consistency, energy levels, and appetite during this time. If you notice vomiting, persistent diarrhoea, or loss of appetite, pause the transition and give us a call.

Here’s a guide you can follow:

DANGEROUS FOODS FOR YOUR PET

HUMAN FOODS THAT ARE (generally) SAFE IN SMALL AMOUNTS

While your pet’s main diet should be complete and balanced, some human foods are safe as occasional treats:

  • Cooked chicken (no seasoning, bones or skin)

  • Cooked pumpkin or sweet potato

  • Plain rice or pasta

  • Apple slices (no seeds)

  • Blueberries

  • Green beans

  • Carrot sticks

  • Banana

  • Broccoli

Always introduce new foods slowly and in small amounts.

If your pet has any vomiting, diarrhoea, or signs of allergy, discontinue and contact us.

 
 

Weight Management for Puppies and Kittens

Maintaining a healthy weight during growth is just as important as choosing the right food. Puppies and kittens grow rapidly in their first 12 months, and their energy needs change quickly, especially during teething, and growth spurts. Proper weight management in this early phase helps lay the foundation for a healthy adult life.

WHY HEALTH WEIGHT MATTERS DURING GROWTH

  • Overweight puppies and kittens are more likely to develop joint problems, grow too fast for their bones, and have a higher risk of obesity as adults.

  • Underweight or undernourished pets may experience stunted growth, poor immune development, and delayed milestones (like teething or coat changes).

  • Rapid, unbalanced growth, especially in large-breed puppies, can increase the risk of orthopaedic issues like hip and elbow dysplasia.

Getting weight management right during this stage supports:

  • Healthy bone and muscle development

  • Balanced energy levels

  • Strong immunity

  • Lifelong joint and metabolic health

HOW TO MONITOR YOUR PUPPY OR KITTEN’S WEIGHT

  • Puppies and kittens can gain weight quickly, so weekly weigh-ins are helpful, especially during their first 4–6 months.

  • Weight alone isn’t the full picture. We use Body Condition Scoring (BCS) to assess whether your pet is underweight, ideal, or overweight.

  • Feeding guides on food packaging are a good starting point but every pet is different. Monitor their appetite, weight, and condition regularly, and adjust portions accordingly.

  • Small and toy breeds may reach adult weight by 6–8 months, while large and giant breeds may continue growing up to 18–24 months. Growth that’s too rapid or too slow can signal a nutrition or health concern.

  • It’s easy to love your new pet with food but treats add up quickly.

If your pet is gaining weight too quickly, we can help you adjust portion sizes, switch to a growth-appropriate food, or recommend a feeding schedule that suits your lifestyle.
