Comfortable quarters for laboratory dogs (1997)

Hubrecht, R. C.

Abstract

Comprehensive enrichment program is outlined. It is reasonable to recommend that as an absolute minimum the enclosure must provide adequate space for a dog to locomote for more than a few paces in a straight line. This can be provided through a dimension of the pen that is at least four times the dog's length. ... Toys or chews that have an appetizing aroma or taste are likely to receive a lot of attention. Such items can reduce the time during which the animals are inactive and decrease destructive behaviour aimed at cage fixtures and furnishings. In a study with beagles, toys/chews (rawhide, plastic pipe, tugtoy) were used by puppies during 64% of the time, and by subadult dogs (7-13 months old) during 24% of the time (Hubrecht 1993, 1995). No habituation effect was noticed. ... Platforms increase the complexity of pens, thus allowing the dogs more choices within their environment. If properly installed so that they do not block the existing floor area, platforms also provide additional horizontal space. In effect, they make use of the otherwise inaccessible third dimension of the pen. ... Dog housing should always be designed so that the occupants can retreat to an area that provides them with a sense of security. Training dogs so that they become used to experimental and clinical procedures is very important in order to avoid stress responses.
