Chalk is a mineral composed of calcium carbonate. It’s found in nature, but it’s also used in many commercial products, including water purification systems, paint and cement. Chalk can be harmful to dogs if they eat too much of it.

Chalk is non-toxic to humans, but dogs have different digestive systems than people, so they may be unable to digest the chalk as easily as we do. As a result, chalk can cause problems for them if they consume it in large quantities.

If your dog eats chalk, he may develop symptoms such as vomiting and diarrhea within 30 minutes to an hour after ingestion. These symptoms usually resolve on their own without treatment after about 24 hours. However, if your dog continues to vomit or has ongoing diarrhea after 24 hours or shows signs of dehydration (such as decreased urination or excessive panting), you should consult your veterinarian immediately.

If your pet has eaten large amounts of chalk at once or several times over a short period of time, it could lead to more serious complications like intestinal blockages or constipation (which can both require surgery).
