In veterinary practice, ear mite infections in dogs and cats may present as a disease that causes intense itching in one or both ears, which in turn triggers scratching at the affected ear. An unusually dark colored ear wax may also be produced. Cats, as well as dogs with erect ears that have control over ear direction, may be seen with one or ...
The ear canals also have numerous sebaceous glands. Together, these two sets of glands produce natural ear wax, or cerumen. Micro-organisms live naturally in this material and give the ears a characteristic slightly yeasty odor, even when healthy. When infected, the ears can give off a strong disagreeable smell.
Signs of ear infection include shaking of the head, and scratching at or under the ear. Some animals may also paw the ear or try to rub it on other objects to relieve pain and discomfort. Ear infections often result in a darker red ear, dirt in the ear, or a general inflamed appearance. Chronic allergic otitis externa in a dog with atopic ...
Earwax, also known by the medical term cerumen, is a waxy substance secreted in the ear canal of humans and other mammals. Earwax can be many colors, including brown, orange, red, yellowish, and gray.
The phenotypes expressed by the genotypes include cerumen type (wet or dry ear wax), osmidrosis (odor associated with sweat caused by excessive apocrine secretion), and possibly breast cancer risk, although there is ongoing debate on whether there is a real correlation of the wet ear wax phenotype to breast cancer susceptibility.
Ear infections are common in dogs, particularly breeds with hanging ears, such as Beagles, and dogs with narrow ear canals, such as Cocker Spaniels. Other predisposing factors include allergies, ear parasites, and hypothyroidism. [76] Deafness* in dogs can be either acquired or congenital.
Main symptoms of swimmer’s ear are a feeling of fullness in the ear, itchiness, redness, and swelling in or around the ear canal, muffled hearing, pain in the external ear and ear canal and especially a smelly discharge from the ear. [9] Constriction of the ear canal from bone growth (Surfer's ear) can trap debris leading to infection. [10]
Otomycosis does not usually cause as much canal skin edema as does acute bacterial external otitis.While a severe pressure type of pain is a prominent feature of advanced cases, the ear is usually much less tender, if at all, to traction or tragal pressure.
