Has your dog eaten vermiculite? Are you worried the vermiculite will make your dog sick? If so, then you’ve come to the right place. We understand it’s scary when your dog eats something he shouldn’t.
In this article, we’ll take a look at vermiculite and whether or not it can make your dog sick. Let’s get started!
What is Vermiculite?
Vermiculite is a natural mineral that can be used in insulation or even in the garden. It’s made of hydrated laminar magnesium-aluminum-iron silicate. It’s often used in gardening because it improves the soil. For instance, it’s a very lightweight material, doesn’t rot, it helps aerate the soil, and increases water and nutrient retention in the soil.
Vermiculite can also be used as insulation in the home. Some of the reasons this material is used for insulation is because it’s lightweight, noncombustible, provides good energy savings, is highly absorbent, pH neutral, inert, and non-reactive (except to the strongest acids).
While this material can be helpful and beneficial in the garden or in the home, what happens if a dog eats vermiculite?
Vermiculite & Dogs
Vermiculite is considered to be non-toxic and inert; however, it can irritate a dog’s stomach and digestive tract.
Another problem is if the dog has eaten a large amount of vermiculite, there’s the possibility the material could cause an intestinal blockage.
