At around 12 weeks, many puppies move into their new home. During the first few days, the rule is: stick to the familiar food, as the puppy already has enough new things to process. Ask the breeder or animal shelter which food the puppy has been eating so far. If you want to change the food, it is best to do so gradually over a period of around 10 days: During this time, continue feeding the familiar food while gradually increasing the proportion of the new food each day.
Food specifically formulated for puppies and young dogs is referred to by manufacturers as puppy food, Puppy food or junior food.
The key factor is whether the product is a complete food or a complementary food. Only a product declared as a complete food provides everything a puppy needs for healthy development.
Good growth food is characterized above all by a high energy content and high-quality, easily digestible proteins.
How much food a puppy needs varies from one individual to another. The current body weight, expected adult size, activity level and energy content of the food are all important factors.
Important to know: The more energy and nutrients a puppy receives, the faster it grows. It doesn't necessarily become overweight, but grows faster – often faster than is healthy for it.
The best way to determine the right amount of food is an individual growth curve, which your veterinarian can create based on the breed and the weight of the parents. Weigh your puppy weekly during the first year of life and compare its weight with the curve.
- With large breeds, it's particularly important to make sure they don't grow too quickly. The rule is: It's better to be slightly too thin than to grow too quickly.
- Small breeds have a higher metabolism and usually complete their growth much sooner than large breeds. Growth rate is taken into account through the amount of food provided.
The right time to switch your dog’s food is when their weight remains stable for several weeks and they are barely gaining any more height.
This indicates that the increased nutritional requirements are no longer necessary. In large dog breeds, bone growth is usually complete by around 14 to 16 months of age.
Here is a rough guide for switching to adult dog food:
- Small (e.g. Havanese, Dachshund) / Up to 10 kg: after around 10 to 12 months
- Medium (e.g. Beagle, Cocker Spaniel) / 10 to 25 kg: after around 12 to 15 months
- Large (e.g. Labrador, Golden Retriever) / 25 to 40 kg: after around 12 to 18 months
- Giant (e.g. Great Dane, Saint Bernard) / Over 40 kg: after around 18 to 24 months
