Ear mites spread rapidly, and can be transmitted from even brief physical contact with other animals. In pets, ear mites most commonly affect cats, ferrets, and to a lesser extent dogs. In rare cases, they may also infect humans. [1] [2] Infected animals have a large amount of crumbly dark brown material in their ears. On close inspection, tiny ...
Canine histiocytoma cytology. A histiocytoma originates from epidermal Langerhans cells of antigen-presenting cell lineage. [4] Spontaneous regression is common in these tumors, and it is mediated by infiltration of CD8-expressing T cells followed by expression of Type 1 T helper cell cytokines (such as Interferon-gamma) and recruitment of antitumour effector cells.
Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]

The Terminologia Histologica (TH) is the controlled vocabulary for use in cytology and histology. [1] [2] In April 2011, Terminologia Histologica was published online [3] by the Federative International Programme on Anatomical Terminologies (FIPAT), the successor of FCAT.
Canine distemper virus (CDV) (sometimes termed "footpad disease") is a viral disease that affects a wide variety of mammal families, [2] including domestic and wild species of dogs, coyotes, foxes, pandas, wolves, ferrets, skunks, raccoons, and felines, as well as pinnipeds, some primates, and a variety of other species.
Pemphigus foliaceus is the most common autoimmune skin disease in dogs, making up around one-third of all canine autoimmune disorders. [16] This disease usually affects areas of the ears and face. [9] Early symptoms are characterized by depigmentation of the nasal palate, dorsal cleft in the mouth, the ear, and the periocular area around the ...
The canal which comprises the internal auditory meatus is short (about 1 cm) and runs laterally into the bone. The lateral (outer) aspect of the canal is known as the fundus. [1] The fundus is subdivided by two thin crests of bone to form three separate canals, through which course the facial and vestibulocochlear nerve branches.
