Clinical signs associated with pseudorabies in dogs.
Clinical signs in dogs with pseudorabies (Aujeszky's disease) were tabulated from 25 confirmed cases. The duration of disease was short, ranging from 6 to 96 hours. Eight dogs were euthanatized. Of those not euthanatized, 12 (71%) died within 24 hours of onset, 16 (94%) died within 48 hours, and only 1 (6%) lived longer than 48 hours (96 hours) after the onset of clinical signs. All of the dogs had ptyalism, 84% were restless, 84% were anorectic, 76% were atactic, and 64% wandered aimlessly. Sixty-four percent of the dogs had tachypnea, 60% had dyspnea, 56% vocalized, 52% were pruritic, 48% held their necks rigidly, 36% vomited, 36% had muscle spasms, 36% were aggressive, 28% had trismus, and 24% had dysphagia. Five of 25 dogs (20%) had abnormal pupillary light responses. Two of the 25 dogs circled and 2 walked backwards. Each of the following were detected once: blindness, ptosis, facial paresis, excessive lacrimation, head-tilt, head-pressing, signs of abdominal pain, and photophobia. All dogs had been exposed to swine, although in some instances the farmer was unaware pseudorabies existed in the herd or believed it was not in the herd on the basis of negative results on serologic testing.
