Last week we asked for your take on the following statement:

“A puppy diet contains more energy and fat per 100 grams than the adult version within the same product range.”

📊 64% of respondents answered “True”.

And honestly, that doesn’t surprise us.

It sounds perfectly logical, after all. Puppies grow fast, so a puppy diet is probably higher in energy and fat too… right?

But the reality is more nuanced.

The name of a diet doesn’t tell you what’s in it

In practice, we regularly hear the advice to switch a puppy that is “growing too fast” onto the adult version within the same product range.

That advice sounds sensible, but without checking the composition it is essentially a guess.

Within a single product range, puppy and adult diets can differ considerably, but by no means always in the way you would expect. Sometimes the adult diet actually contains more energy, sometimes less. The levels of calcium, phosphorus, protein and the calcium-to-phosphorus ratio can vary substantially too.

In other words: the category ‘puppy’ or ‘adult’ says surprisingly little about the actual nutritional value.

So how should you approach it instead?

With a puppy growing faster than desired, it’s wise not to switch diets straight away, but first to answer a few questions:

✔️ Does the diet’s composition suit this particular puppy?
✔️ Is the puppy getting the right amount of food?
✔️ How much additional energy is coming from treats, training rewards and chews?

That last point is easily underestimated. The feeding guide on the packaging almost always assumes the diet is the only source of energy. Young puppies in particular tend to receive plenty of extra rewards during training and socialisation, so total energy intake can creep up considerably without anyone noticing.

Monitoring growth is at least as important

Growth monitoring is the way to prevent overly rapid growth and growth problems.

That’s why we recommend weighing puppies regularly:

• up to 6 months: every 2-3 weeks;
• from 6 months: roughly once a month.

Then adjust the feeding amount based on the new weight and the rate of growth, not on the packaging chart alone.

The key takeaway?

Don’t look at the name on the bag. Look at what’s inside the bag.

Good nutritional advice doesn’t start with the “puppy” or “adult” category, but with the nutrients, the individual puppy and their rate of growth.

That’s exactly why, at FeedWise, we always work from the composition of the diet combined with the characteristics of the animal. It lets you build nutritional choices on facts rather than assumptions.
