how many bones do dogs have

Dogs typically have about 320 to 321 bones in their skeleton, with the exact count varying mainly due to the length of the tail and the presence or absence of extra digits (dewclaws) on the feet. A common, widely cited figure is approximately 319–321 bones for an adult dog, but longer-tailed breeds can have more vertebrae in the tail, which raises the total by a small amount. Short-tailed or docked-tailed dogs will have fewer vertebrae in that region, reducing the overall count accordingly.
