This makes it a valuable source of these vital components to the dog’s diet.

Some of these trace elements can be hard to obtain without the use of supplements otherwise.

Thus montmorillonite clay can play a crucial role in ensuring a healthy nutrition for your four-legged companion.

Is Montmorillonite Clay Bad for Dogs?

No matter how healthy a substance is, anything in excess can be bad and unhealthy for an organism. The same applies to montmorillonite clay.

That said, it is unlikely that this clay will harm your dog. This is due to the limited quantities used within dog food.

Too much clay would make the formula unpalatable anyway.

As a result, it is very difficult to feed your animal unhealthy quantities of montmorillonite clay.

Sources of Montmorillonite Clay in Dog Food

Montmorillonite Clay is abundant naturally. So it is sourced from nature.

Therefore, there is little need for manufacturers to create it artificially. Although, it can be done.

Thanks to this, you can be sure that the Montmorillonite Clay in your animal’s food was found naturally. Sources include:

  • Soils
  • Volcanic ash

In areas with active volcanoes, the material is available in large quantities.

How Much Montmorillonite Clay Do Dogs Need?

Montmorillonite Clay is an inorganic substance. As a result, you can treat it as a dietary supplement rather than an actual part of the animal’s nutrition.

Hence, your pet only needs trace quantities within their diet.

Add to this its role as a clumping agent, and you can count on manufacturers to include only the required minute amounts.
