Abstract

The objective of the present work was to study the characteristics in common and the differences observed in the intoxication by amitraz 1 mg/kg, IV, in dogs and cats. The main clinical signs observed in common were sedation, hypothermia, bradycardia, bradyarrhytmia, hypotension, bradypnea, mydriasis and transitory hyperglycemia, however the intensity of these signs was different among the species. The hypothermia was more accentuated in cats than in dogs. The dogs were more sensitive to the cardiorespiratory alterations presenting more significant decrease in the heart and breathing frequency, besides occurrence of larger bradyarrhytmia number. The cats presented more prolong mydriasis than the dogs. It was observed hyperglycemia and transitory hypoinsulinemia and transitory decrease of the plasmatic levels of cortisol, however the cats presented a hyperglycemia pick more accentuated and more precocious than the dogs, and regarding the plasmatic levels of cortisol, the dogs presented a decrease more accentuated than the cats. In the medium time of return of the sedation smaller in cat. These results demonstrated that the amitraz intoxication between dogs and cats is very similar, however the cats showed more sensibility to the hypothermia and hyperglycemia induction, besides mydriasis and the medium time of return of sedation more prolong, while the dogs presented a decrease more accentuated in the cardiorespiratory parameters and of the plasmatic levels of cortisol than the cats.
