What terrier breeds have black gums?

Certain terrier breeds, such as the Boston Terrier and the American Staffordshire Terrier, are known to sometimes have black gums. This trait can be a result of genetics and pigmentation, rather than a sign of health issues. It's important for dog owners to monitor their pets' overall oral health regardless of gum color. If there are any concerns about a dog's gums, a veterinarian should be consulted.
