Puppy food is designed to meet all your puppies needs as they grow. Feeding them the right food will set them up for a healthier adulthood.

The growth phase of your puppy lasts from weaning until adulthood. This will vary from breed to breed. Your puppy’s growth is complex, and nutrition plays a significant role in ensuring your puppies wellbeing. Nutrition directly affects the immune system of your puppy as well as their body condition and the development of their joints, bones, and growth rates. 

Puppy food ensures your puppy has the perfect energy required for their needs. It has the correct vitamins and minerals required. In the first weeks after they are weaning, the growth rate of your puppy is rapid, and they use half their daily food intake for growth.

It’s useful to monitor weight and body condition. This will arm you with the best information to guide your puppy through those important months of their development.

Weight, energy and body condition

Your puppy’s food must contain –

• Protein
• Carbohydrates
• Fat
• Vitamins
• Minerals

If your puppy is fed a complete balanced food, they should not require any supplements.

Your puppy will require more nutrients and energy than an adult dog because they are growing. As they get older the growth rate will slow and more of their food intake will be used for their daily needs instead of growth. 

While in the growth phase, it’s important to monitor your puppies body condition every couple of weeks, as this will allow you to adjust their feeding amounts as needed. If they develop an over ideal body condition it can lead to the development of joint and bone problems contributing to health issues as adults.

Size

Puppies come in varied sizes, and these differences can be affected by different puppy nutritional needs. Large and giant breeds have different protein and nutrient requirements than small breeds. Too much protein or calcium can have negative effects for giant breed puppy’s joints and bone growth. Larger breed puppies also have a slower growth phase compared to small breed puppies.

Breed

It’s worth considering your puppy’s specific breed as these differences can have an impact on their nutritional needs.

Some breeds are known to suffer from certain health conditions that can be affected by their feeding. Some breeds are known to have hearty appetites and eat fast. Food manufacturers might help this with shaped and textured foods designed to slow eating and encourage chewing.

Giant breeds are known to be at risk of bone problems while growing if not fed correctly. Adjusting their food can limit these risks. Additionally changes to energy levels and digestibility in foods can affect growth and manufacturers will often supplement foods with essential fatty acids to support joint health.

It is important to understand how nutrition can impact your puppy’s growth and development and how you can directly influence this. There is a varying array of products, and a good understanding of your pets’ needs can help you to make informed choices in their diet.
