The effects of cage size and pair housing on exercise of beagle dogs.
One of the requirements of the 1985 amendments to the Animal Welfare Act is the establishment of an exercise program for dogs. Assumptions have been made by some that larger cages or the presence of a companion animal will motivate exercise. To examine how cage size, pair housing and human contact affect exercise, a study was conducted using a computerized video-data acquisition system that measured distance traveled and time spent moving in 1 x 1 m, (single only) and 1 x 2 m (single and paired) and 1 x 1.5 m cage (paired only) cages. Male beagle dogs (n = 6) housed singly in the 1 m2 cage traveled an average of 55 m/hr spending only 8% (57 min) of the 12 h photo period in motion. When the cage size was doubled, the average distance traveled decreased to 13 m/hr and the time spent moving increased to 11% (77 min/day). When dogs were pair housed in a regulation size cage, the average distance traveled decreased to 8.6 m/hr and they spent less than 6% of the day in exercising (42 min/12 hrs). The greatest amount of exercise was seen when dogs were housed as a pair in a cage less than recommended size (an average of 109 m/hr and 8.8 min/hr). Therefore, these data indicate that larger cages or pair housing in regulation size cages have little or no effect on the activity of purpose bred male beagle dogs. There was, however, a direct correlation between activity, time and distance, and the presence of humans in the animal room.(ABSTRACT TRUNCATED AT 250 WORDS)
