Effect of feeding patterns on performance of a visuospatial memory task in the beagle dog: A novel cognitive-based protocol for assessing satiety

Developing the Second Generation of Improvised Explosive Device Detector Dog

“…The system designed by CanCog™ has been used by other investigators to evaluate cognitive function in dogs following aging, dietary manipulation, and pharmaceutical administration (Araujo and Milgram, 2004;Callahan et al, 2000;Chan et al, 2005;Milgram 2003;Studzinski et al, 2005). These and many other experiments have shown that object discrimination and reversal learning are influenced by function of age, task difficulty, pre-existing object preferences, and other factors.…”

“…For some analyses, the number of trials was right censored at 300 with the error rate calculated accordingly. Response accuracy has proven to be a powerful behavioral indicator of learning and memory performance in dogs tested in the CanCog TM system (Callahan et al, 2000;Chan et al, 2005, Head et al, 1998, Milgram et al, 1994Tapp et al, 2003).…”

Insights to Study, Understand and Manage Extruded Dry Pet Food Palatability

“…Specific palatability protocols are then necessary to prevent biased results. However, it is notable that nutrient needs, sensory abilities, and behavior differ depending on age, sex, reproductive status (neutered or intact), and breed [72,81,84,85]. Hall et al [81] noticed that consumption of calories from protein would differ in cats or dogs according to their age and fat or lean body.…”

“…A regression tree analysis demonstrated that cats with the lowest lean body mass tended to consume more calories from protein, while this is also true for dogs with the highest fat body mass. Age may also affect appetite as well as sensory performances; for example, Chan et al [84] emphasized reduced sensory-specific satiety in older dogs as in humans, while Pekel et al [36] and Kokoci ńska-Kusiak et al [72] stated a degeneration of olfactory and taste capacities in aged cats and aged dogs. These studies also reported that sex differences may be observed with a higher activity of olfactory cells in female dogs.…”
