Wednesday, July , 2026
Care and advice
Feeding a puppy is one of the most important decisions we make when a new furry member arrives home.
During their first months of life, puppies grow at a rapid pace and need a specific diet that provides them with all the essential nutrients they need to develop healthily and strongly. However, with so many options and opinions out there, choosing the best food can be a real challenge.
In this guide, we explain, in a clear and simple way, what a puppy's diet should include, the different types of food available, and the most common mistakes to avoid. Because a good start makes all the difference.
What does a puppy need in its diet?
Just like human babies, puppies need a specific diet to help them develop properly. Their bodies are in the midst of growth, and that requires a balanced combination of nutrients to support the development of their bones, muscles, organs, and immune system.
Here we tell you what you can't leave out of their bowl.
Proteins, fats, and calcium: the basic building blocks
· Proteins: these are essential for building muscle and strengthening the immune system. The source should always be high quality, preferably meat or fish.
· Fats: provide energy, promote brain development, and help maintain healthy skin and a shiny coat.
· Calcium and phosphorus: essential for bone growth and the development of strong teeth. The balance between these two minerals is key to preventing joint problems.
Growth stages and nutritional needs
Not all puppies grow at the same rate. A small breed dog reaches its adult size earlier than a large breed dog, and this also influences its diet.
· From 0 to 2 months: ideally, they should be fed breast milk or specific formula if this is not possible. · 2 to 6 months: they begin to try solid foods. They need specific puppy food that is rich in energy and nutrients. · 6 to 12/18 months: their diet should be adapted to their growth rate. In large breeds, this process can last up to 18 or 24 months. It is always advisable to choose a food formulated for their age, size, and activity level.
Types of puppy food
When it comes to feeding a puppy, there is no single right answer. The important thing is that it meets their nutritional needs, is safe for their age, and agrees with them. Here we explain the main alternatives.
Dry food vs. wet food vs. BARF
· Dry food: this is the most common option. It tends to be more economical, easy to store, and good for dental health. If you choose a high-quality brand formulated for puppies, you will have a complete and balanced option.
· Wet food: more appetizing and easier to chew, ideal for puppies who are just starting to eat solids or have trouble biting. It contains more water, so it is lower in calories, but it tends to be more expensive.
· BARF (raw or natural) diet: consists of feeding raw meat, offal, meaty bones, vegetables, and fruit. It is a more natural option, but it requires knowledge, veterinary supervision, and good management to avoid risks of contamination or imbalances. Homemade food: yes or no? Preparing food at home may seem like a good idea, but it is not always the best option for a puppy. Although it allows you to control the ingredients, it can be difficult to ensure the nutritional balance they need. If you choose this option, it is essential to consult with a veterinarian or canine nutritionist to design an appropriate menu and avoid deficiencies.
How to choose the best food for your puppy
With so many brands and formats on the market, choosing the best food for your puppy can be overwhelming. But don't worry: with a little information and attention to detail, you can make a good decision.Read the labels carefully. Before getting carried away by the packaging or advertising, look at what really matters:
· Ingredients: the first ingredient should be a source of high-quality protein (meat or fish).
For puppies, protein should be around 25-30% and fat between 10-20%.· Specifications by age and size: make sure the food is specifically formulated for puppies and, if possible, also adapted to their size (small, medium, or large).
· Avoid: low-quality meat by-products, artificial colors, and excess grains.
Consult your veterinarian
Every puppy is unique, and what works for one may not be right for another. Your veterinarian is your best ally for:
· Detecting food intolerances or sensitivities.
· Adjusting their diet if your puppy is overweight, very active, or belongs to a breed with special needs.
· Monitor growth and nutritional development.
Good food is an investment in their long-term health.
Common mistakes when feeding a puppy
Even with the best intentions, it's easy to make mistakes when feeding a puppy. Some may seem harmless, but they directly affect their health and development.
Feeding adult or human food
One of the most common mistakes is feeding food intended for adult dogs or, even worse, human food scraps. Neither of these options meets the nutritional needs of a growing puppy.
Adult food tends to be lower in calories, protein, and calcium, which can lead to poor bone and muscle development. Human food, on the other hand, may contain ingredients that are dangerous to dogs, such as onions, garlic, excessive salt, or saturated fats.
Changing brands without a transition period
Another common mistake is to change brands or types of food abruptly. This can cause digestive problems such as diarrhea, vomiting, or loss of appetite.
Whenever you change your pet's food, do so gradually over at least 5 to 7 days. Start by mixing a small amount of the new food with the old food and gradually increase the proportion of the new food.
Conclusion
Choosing the right food for a puppy is not just a matter of brands or tastes: it is a decision that directly influences their health, energy, and growth. Understanding what they need at each stage, knowing the different options available, and avoiding common mistakes will help you provide them with a balanced diet from day one.
Remember: every puppy is unique, and there is no single perfect formula. Listen to your veterinarian, observe your furry friend, and always opt for quality and consistency.
