TUCSON, Arizona — University of Arizona researchers have developed a roughly 40-minute assessment that uses food-based tasks to study memory and behavioral flexibility in aging dogs.
The tool, called CANID, was tested with 239 dogs in Tucson and California, according to the university’s account of research published in Animal Cognition. Many animals were assessed again after six months or a year.
The tasks include remembering the location of a hidden treat and adapting when a familiar route to food is blocked. Researchers say the approach may help identify subtle changes before obvious signs of cognitive dysfunction appear.
CANID requires trained staff and specialized equipment; it is not presented as a home diagnostic test. The work is a research tool, and changes in a pet’s behavior should be discussed with a veterinarian.
