Normally, a well fed and well cared dog, a dog that exercises enough, will happily live for many years. Nevertheless, recognizing the first symptoms of any health problem is part of the owner's responsibility. Fulfilling these responsibilities will turn to be a lot easier if the owner understands how the animal's body work.

THE SKELETON
The skeleton is the frame over which the dog's anatomy is structured. Along with a complex systems of muscles and tendons, it allows the dog to stand on its paws, sit, run, jump or walk. The muscles, firmly anchored on the bones, are the ones that put the dog's skeleton in motion.
The bones are hollow tubes with a hard and calcified weave filled with bony marrow. They are fed by blood vessels that lead to the inner part through very little holes. When a bone breaks, new cells are formed on its surface, they are designated to fill in the crack. During development, the long bones of the limbs grow by the edge in a process, controlled in a great deal by hormones, which stops when they reach maturity. Dog Training
Differently from humans, dogs grow from the collar bone, the front paws are attached only to the body through muscles, which provides the dog a great freedom of movements. big dog kennels
All the dogs have 30 real vertebras, that are added to the ones in the tale. The number of vertebras there varies from one breed to another. Of the real vertebras, 7 are cervical (neck frame), 13 are thoracic (back frame) and they are attached to the ribs. Other 7 vertebras are lumbar (kidney frame). The spinal cord is located in the channel formed by the vertebras of the spinal column, with the purpose of protecting such a vital organ.
CONFIGURATION OF THE JAW
The type of bite, or the way in which the upper teeth fit with the lower ones, is determined by the length of the lower jaw. There are four types of bite: the scissors bite (the upper teeth perfectly fit with the lower ones); the prognatic bite (the lower teeth are ahead compared to the upper ones because the jaw is bigger than the maxillary); the protrude bite (the lower teeth are behind the upper ones because the lower jaw is smaller than the maxillary) and the normal or standard bite (the upper and lower teeth are lined up to the same level). All these configurations of the jaw are correct as long as they fit with the morphology of each breed. For example, the prognatism would be an inadmissible defect on a Golden Retriever, while it is perfectly normal of a Bulldog. The type of bite can enormously vary among the breeds and it is clearly specified on their respective standards.
THE TEETH
Adult dogs have a total of 42 pieces. The incisive teeth are used to cut; the canines, to tear apart and the molars to break and chew. The dogs also have some special teeth, very strong, called carnivorous teeth, that let them chew even the hardest materials. heated dog houses
SKULL SHAPES: The skull shape in a dog varies from one breed to another, even when the bones that are part of it are the same in all the cases. There are three types of very different morphologies.
The breed with narrowed and elongated skulls, as the Afgans, are called Dolicocefalous, while the ones with flattened skulls, as the Bulldogs and the Boxers, are called Braquicefalous and the ones located among these extremes are known as Mesocefalous.
No matter what the shape it is, the skull always create a closed cavity, which upper part is named cranial cavity. The maxillar bone constitutes the upper jaw and the lower jaw is attached to the skull through an articulation.
The bony sheets that form the cranial cavity are welded in the center of the frontal zone after birth, as well as it occurs with human babies.
In some breeds in which the skull is too convex, as the Chihuahua this process doesn't occur in a complete way, what makes the dog specially vulnerable to brain damages. cat house heater & outdoor cat house |
