title: Effect of environmental stimuli on the core temperature of nervous dogs.
abstract: Temperature sensitive radio transmitters were implanted into the abdominal cavities of two substrains of pointer dogs to monitor the core temperature during a 12:12 L/D cycle. The results obtained from dogs of a nervous, person-aversive strain were best described by a partially-rectified sine curve, with well defined maxima during the light period. When similarly tested in a situation with minimal diurnal stimulation, the variation in temperatures was reduced. Temperatures of normal pointer dogs, kennel-mates of the nervous dogs, fluctuated very little by comparison. Their data fitted a straight line about as well as a sine curve.
