How many vertebrae are in a dog's sacrum? - in detail
The sacrum is an essential component of the spine, and its structure can vary among different species. In dogs, the sacrum typically consists of five fused vertebrae, although this number can occasionally be four or six in some breeds. These vertebrae are strategically located at the base of the spine, between the lumbar region and the tail, providing crucial support for the pelvis and hind limbs. The fusion of these vertebrae into a single bone enhances stability and strength, which is vital for the dog's mobility and overall skeletal integrity.
