“Restoring” the microbiome. Do we actually know what we are doing?

A dog with persistent gut problems. A modified diet, a probiotic, a fibre mix, some herbs and yet another supplement to “cleanse” the gut.

All with the best of intentions. But what exactly are we treating?

The microbiome is attracting a lot of attention. Rightly so, because the micro-organisms in the gut play an important role in health. At the same time, the promises about “restoring”, “resetting” and “cleansing” sometimes seem to go further than our knowledge.

We know more and more. But it is by no means always clear which product, at which dose, actually benefits which patient. And a change in the composition of the microbiome does not automatically mean that the animal feels better.

Especially with a sensitive gut, I see that as a reason to be careful with everything we add.

A supplement often contains more than the ingredient on the front of the package. Flavourings, protein sources, carriers and added fibres are also part of what the animal takes in. They need not be a problem, but they do deserve attention, for example during an elimination diet.

And when we use several products at the same time, all these extra ingredients add up, and it becomes increasingly difficult to judge what helps, what does nothing and what may be causing problems.

With all those well-meant additions, are we sometimes causing more disruption than improvement?

Targeted support can make sense. For me, though, it comes with a clear question: why this product, for this animal, and how will we notice that it helps?

Sometimes good gut care starts with adding less or leaving things out, choosing an appropriate base diet and evaluating carefully.

Restraint is also a deliberate treatment choice.
