Cats, as well as dogs with erect ears that have control over ear direction, may be seen with one or both ear pinnas held at an odd or flattened angle. The most common lesion associated with ear mites is an open or crusted ("scabbed") skin wound at the back or base of the ear, caused by abrasion of the skin by hind limb claws, as the ear has ...
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]
Cropping the ears of livestock guardian dogs was, and may still be, traditional in some pastoral cultures.The ears of these guardian dogs—such as the Caucasian Shepherd Dog [6] and the Maremmano-Abruzzese Sheepdog—were traditionally cropped to reduce the possibility of wolves or opponent-dogs getting a grip on them.
The repellent, such as Vectra 3-D, keeps mosquitoes from feeding on the dog and transmitting the L 3 stage worms. If a dog is bitten, the heartworm preventive takes over when administered. If a mosquito feeds on a heartworm positive dog on a repellent, they do not live long enough for the microfilaria they ingested to molt into the infective L ...
So far, EAR is the only processive antitermination system specific for Gram-positive bacteria. Further experiments failed to reconstitute EAR-mediated processive antitermination mechanism in vitro or in a Gram-negative heterologous host ( E. coli ), suggesting that additional B. subtilis -specific factor(s) may also be required for EAR ...
