What Happens If a Dog Eats Vaseline?

Vaseline is non-toxic, and a dog can consume it safely in small quantities, usually resulting in diarrhea and vomiting. In large enough amounts, petroleum jelly functions as a laxative. The American Society for the Prevention of Cruelty to Animals claims that ingesting Vaseline is largely harmless, but inhaling it poses a slight risk for aspiration pneumonia. The ASPCA advises pet owners to keep jars of Vaseline away from their dogs.
