Dog Sense of Hearing
Ear Problem in Dog.
Healthy dogs have a good a sense of hearing, as any dog owner who have tried to open a can without making noise can confirm. Dog Sense of Hearing & Ear Problem in Dog can detect the noise in a six hundredth of a second and many of them, using the muscles located on the ear to canalize the sound, are capable to hear four times further away than us.
Even the shape of the ear varies from one breed to another, the ear anatomy and the inner and central ear functions are always the same. The outer ear is formed by cartilage, muscle and skin, and in the majority of dogs it possesses a great mobility. It is used to catch the sounds and canalize them throughout the auditive conduct up to the eardrum, a membrane that vibrates when it is reached by the sound waves. dog pulling harness
The middle ear is located on the other side of the eardrum. It is a chamber that lodges some little bones called the malleus, anvil and stirrup due to their shape and function. They are, in fact, the tinniest bones in the whole body and they are in charge of transmitting the eardrum vibrations to the inner ear, as well as amplifying them.
Once in the inner ear, an organ with a spiral shape, called cochlea is in charge of transforming these vibrations into signs that can be interpreted by the brain, where they are actually sent. We can also find, in the inner ear, the balance organs that, besides fulfilling that function, keep the dog permanently informed about the lining of its head having the floor as a guide. home remedy for dog ear mites
THE SHAPE OF THE EARS
The ear has been the most modified part of the body of the selective breeding. In its natural state, the dog's ears should be identical to the its direct ancestor, the wolf. The ears of a wolf, straight and extremely mobile, allowing them to hear any sound in the environment, having 17 muscles each and can move independently.
Currently, you can find as many ear shapes as breeds. Some dogs, as the German Shepherd, keep the little and erected ears of the wolf, which gives them a more alert and lively aspect. Other breeds, as the Bloodhound and the Cocker Spaniel (that probably lack of such fine hearing sense) possess big ears that heavily hang over the cheeks. There are also some breeds with big, erected ears, similar to the bat's ears such as the French Bulldog and the Boston Terrier, for example. dog tee shirt
The selective breeding, once again, has brought along health problems. Even though it is normal to have no hair on the extern auditive conduct, the genetic alterations caused on the skin of the ear, have caused that some breeds grow hair on the inner part of that conduct, making it necessary to wax the hair out.
A SIXTH SENSE?
Some owners assure that the dog possesses a sixth sense that allowed them to even guess their owner's thoughts. Though there are dogs that begin to show happiness before their masters prepare dinner for them or take them for a walk, we can not attribute this conduct to telepathy. We should understand that the dogs are capable to catch even the most imperceptible gestures of their masters and interpret them correctly and allowing them to notice it when the owner has taken the decision of standing up to go to the kitchen or outside the house and in the kennel.
It is known, in fact, that there are some dogs capable to detect even the dilatation of their master's pupils. However, there are other behaviors that are a lot more harder to explain such as when the dog foresees the return of its master from a trip or in those cases in which the dog howls at the same time its owner dies. In other cases, dogs travel several hundreds of kilometers just to meet their masters, going through, until that moment, a totally unknown way. Undoubtedly, there is a lot left to understand and explain when talking about dog's senses.
