Gypsum is a soft sulfate mineral that is commonly used in a variety of household products like drywall, plaster, and cement. It is also sometimes added to foods like tofu or soy milk as a calcium supplement. This has led some dog owners to wonder – is gypsum toxic to dogs?
The short answer is gypsum is generally not toxic to dogs when consumed in small amounts. In fact, it is considered non-toxic by the FDA. However, there are a few things owners should keep in mind regarding gypsum safety:
- In large quantities, gypsum can cause stomach upset or constipation. Pups that get into drywall or joint compound may experience vomiting, diarrhea or abdominal pain from eating too much gypsum. While small ingestions are not a concern, large amounts should be avoided.
- Gypsum dust can be an irritant. Breathing in gypsum dust from construction materials or other sources may cause coughing, sneezing or nose/eye irritation in dogs. It's best to keep pups away from areas where gypsum dust is in the air.
- Some gypsum products contain additives. While pure gypsum is non-toxic, some gypsum materials like drywall joint compound contain starch, glue or other additives. These extra ingredients may cause more stomach upset if dogs ingest them. Check product labels before use.
- Hydrated gypsum can burn. When mixed with water, gypsum forms calcium sulfate dihydrate which can reach high temperatures as it hardens. This means wet gypsum can potentially burn paws or skin, so keep dogs away during construction projects where gypsum is being mixed.
- Long-term impacts are unknown. While occasional small ingestions of gypsum are not a concern, some sources recommend limiting exposure over a lifetime due to unknown long-term effects. It's smart to keep gypsum-containing products out of a dog's reach whenever possible.
Overall, most veterinarians agree that occasional, incidental ingestion of gypsum does not warrant panic or an emergency trip to the vet. Pups that consume small amounts may experience no ill effects at all. But gypsum should not be fed purposely and large amounts can cause issues. Keep all construction supplies, joint compound, spackling, plaster, and foods containing gypsum supplements safely out of your dog's reach. Call your vet if you notice vomiting, diarrhea or other concerning symptoms after exposure to gypsum. With sensible precautions, gypsum does not pose a serious toxicity risk for most canine companions.
