Does a burnese mountain dog have extra toes?

No, Bernese Mountain Dogs do not typically have extra toes. Like most Dog Breeds, they generally have four toes on each foot, along with a dewclaw on the inner side of each front leg. Some breeds may have polydactylism, which is the condition of having extra toes, but this is not characteristic of Bernese Mountain Dogs. If a dog has extra toes, it may be a genetic anomaly rather than a breed standard.
