Pseudorabies - Page 1

Swine are usually asymptomatic, but PRV can cause abortion, high mortality in piglets, and coughing, sneezing, fever, constipation, depression, seizures, ataxia, circling, and excess salivation in piglets and mature pigs. Mortality in piglets less than one month of age is close to 100 percent, but it is less than 10 percent in pigs between one and six months of age.[9] In cattle, symptoms include intense itching followed by neurological signs and death. In dogs, symptoms include intense itching, jaw and pharyngeal paralysis, howling, and death. In cats, the disease is so rapidly fatal that there are usually no symptoms.[1] Any infected secondary host generally only lives two to three days.[6]

I only know of one dog that had this and, of course, tha dog died.  There is no prevention. Hog farm was most likely source. No issue for people.

Again, very rare. Are you just randomly picking diseases? Dogs are usually not aggresive, and the length of the disease varies. Cats have an excitement phase, preceded by lethargy, salivation and mewing becomes prevelant. Pruritis may or may not be seen.
