Companion Animals Symposium: Environmental enrichment for companion, exotic, and laboratory animals.
One intent of the proposed changes to USDA 9, CFR Part 3 was to give kennel dogs an opportunity for exercise and play (socialization). Increasing cage size was proposed as a means to encourage exercise and play, thus enhancing the well-being of kennel dogs. Eleven-month-old, female, purpose-bred Beagles, housed four to a cage, were videotaped for 15 hours on 10 different dates, resulting in five videotapes recorded for a smaller cage size and five videotapes recorded for a larger cage size. A total of 40 dogs were videotaped. For each videotape, aggression, play, and distance between dogs were recorded and analyzed. There were no differences in aggression or play, but the dogs did put significantly more distance between themselves in the larger cage.
