Ear infections can be no less troublesome in dogs than they can be in humans. Add to the problem an infestation of ear mites, and you're guaranteed to have a restless, unhappy pet, one that's constantly shaking its head and scratching at his ears.Ear mites are easily treated by cleaning the ears with a medicated ointment. However, you'll need to get a solution from your veterinarian, since most mites have become resistant to the chemicals (sevin, pyrethins and thiabendazole) used in over-the-counter preparations.

Hearing loss in dogs, as in humans, can be caused by a wide range of disease, trauma, and/or congenital problems. In congenital cases, the dog is born deaf. Hearing loss can come on suddenly or gradually due to injury, disease, ear infections, exposure to loud noises or explosions, or simply the wear and tear of old age.Hearing loss is categorized as unilateral (affecting one ear only) or bilateral (affecting both ears). Dogs with white or partially white coats are often subject to a congenital form of deafness connected with the special pigmentation in their skin. In these cases the dog may have unpigmented skin in the inner ear, which causes the nerve endings inside the ear to wither away and die when the affected puppy is only a few weeks old.

Healthy cats will have clean ears. The inside of the ear will be pink and odor free. They will not have scratches or hair loss around the ears nor will they have ear wax buildup inside of the ear.The first acute sense in a cat is the sense of sight, while the second is sound. Their sense of sound is magnified compared to humans. A feral cat must be able to hear vermin running across the field to alert it that it is time for dinner. The sense of sound develops about the second week of life so that a baby kitten can hear its mother purring.When the inside of the ear is unhealthy it could be caused by a fungal infection or ear mites. The signs include extremely red ears, dark discharge or ear wax buildup. [...]
