To continue with the skeletal structure of the dogs anatomy we take a look at the extremities. Dogs have seven cervical neck thirteen thoracic chest seven lumbar back three fused sacral tail bone and a variable number of tail vertebrae.
Each extra vertebra adds about 15 mm to the length of the carcasses at slaughter weight.
Vertebrae number dog. How many vertebrae do dogs have. The number of dog vertebrae may vary in the different breeds. But usually you will get seven cervicals thirteen thoracics seven lumbar three sacral vertebrae and fifteen to nineteen caudal vertebrae in the dog skeleton.
Similarly it is asked do all dogs have the same number of vertebrae. If you look closely both the human and canine spines have 7 vertebrae in the neck cervical humans have 12 vs 13 in dogs vertebrae in the mid back thoracic spine and 5 vs 7 in the canine spine in the lower back lumbar spine.

One may also ask do dogs have a coccyx.
Vertebrae was determined by reviewing ventrodorsal radiographs of pelvis with an extended hip of 1878 dogs. Lumbosacral transitional vertebrae were detected in 188 dogs 10. German Shepherd Alaskan Malamute and Bohemian Shepherd were found to be.
They are found dorsal to the line of the transverse processes of the vertebrae and are arranged in three parallel columns. Lateral column Iliocostalis arises from the ilium and transverse processes of the lumbar vertebrae to insert on cranial lumbar vertebrae and ribs spanning about 4 vertebrae. Normal dog have usually 7 lumbar vertebrae and 3 sacral vertebrae.
Unfortunately the dog used for this anatomical module presented a vertebral transitional anomaly with only 6 free lumbar vertebrae. For educational purpose we decided to numerate lumbar vertebrae until 7 but if you have any question dont hesitate to contact us on Imaios Support. The vertebral column originally develops as a series of 33 vertebrae but this number is eventually reduced to 24 vertebrae plus the fused vertebrae comprising the sacrum and coccyx.

The number of thoracic vertebrae each bearing left and right ribs ranges from 13 to 17. There are seven cervical vertebrae twelve thoracic vertebrae and five lumbar vertebrae. The number of vertebrae in a region can vary but overall the number remains the same.
The number of those in the cervical region however is only rarely changed. Number of Vertebrae Cervical Length of Total Fused Vertebrae Thoracic Lumbar Caudal Antinclinal Vertebra Contra-antinclinal Vertebra Total Number. 7 3 12 andor 35 possibly 67 1214 23 1619 30 2427 44 7 L.
13 the others are variable 15. The thoracic spine has 12 vertebrae which are numbered from T1 through T12. It provides attachments for the rib cage and provides stability for the upper body.
Total number 33. A detailed account of the number of vertebrae in human beings as well as their names and characteristics have been provided below. 5 Vertebrae Ribs and Sacrum.
Count the number of thoracic intervertebral and lateral vertebral foramina in the bovine and equine skeletons. The total should be 13 for the ox and 18 for the horse. Modified from Guide to Dissection of the Dog 7th ed.
Caudal vertebrae are the bones that make up the tails of vertebrates. They range in number from a few to fifty depending on the length of the animals tail. In humans and other tailless primates they are called the coccygeal vertebrae number from three to five and are fused into the coccyx.
