Dog sensor organs
Feels include visual, hearing, smell and taste organs. Some nervous system diseases, but the normal connection between the sensation of the organs and the central nervous system causes the corresponding sensory dysfunction.
1. Visual organs: Pay attention to whether the eyelids are swollen, corneal integrity, prominent eyeballs or depression during inspection.
1. Sbining: The eyeball position is not right, due to the paralysis of the eye muscles or the excessive tension of the eye muscles on one side.
2. Eye tremor: is a series of rhythmic fast round trips in the eyeball. Its movement form has a horizontal direction, vertical direction, and turning direction. It shows that the injury to the nerve nucleus dominating eye muscles is found in semi -regulatory and cerebellar diseases.
3. Puppets: Pay attention to the size, shape, symmetry on both sides, and the response of pupils to light. The pupil response to light is an effective test method to understand the functional activity. Use a flashlight to quickly illuminate the pupil from the side to observe the dog's reaction state. If you are healthy, your pupils will shrink quickly and will recover after removing radiation.
Pupil expansion: The results of painful diseases, high excitement, use of antibrok alkaline or encephalopathy with increased intracranial pressure to shrink the pupil radiation muscle.
Pupil narrowing: is the result of the dynamic eye nerve excitement or sympathetic nerve paralysis that causes the pupil sphincter to shrink. Seen in encephalitis, brainwater water and other diseases.
Pupitive size asymmetry: The pupils on both sides are different, the changes are uncertain, accompanied by slow or disappearing the light response, indicating that the brain stem is injured.
4. Visual: When the dog moves through the obstacle, it collides on the object, or does not show dodge when it shakes in front of the eyes, and does not have closed eyes.
2. Hearing organ
Active enhancement is the side of the sick dog that turns his ears to the source of the sound, or moves back and forth with both ears, and shows that frightening in brain and meninge disease. The weakening or disappearance of the hearing is related to the damage to the cerebral cortex.
Use dogs familiar with or aromatic materials to let the dogs smell, but prevent it from seeing and observing its reaction. Healthy dogs usually look for or increased chewing or saliva secretion.
