The effects of exercise and diet on olfactory capability in detection dogs.

A previous work suggests that dietary fat may influence canine olfaction. The present study evaluated whether olfactory performance could be influenced by forms of dietary fat and exercise. Seventeen certified detection dogs were fed three different diets (high fat, low fat or high polyunsaturated fat) for 12 weeks.

Evaluation of exercise-induced changes in concentrations of C-reactive protein and serum biochemical values in sled dogs completing a long-distance endurance race.

Objective: To determine whether long-distance endurance exercise in sled dogs causes increases in serum concentrations of C-reactive protein (CRP) and whether such increases are correlated with other markers of the exercise-induced acute-phase response.

Animals: 25 sled dogs.

Procedures: Serum was obtained from 25 sled dogs approximately 48 hours before and immediately after completing a race of 557 km.

Hematologic, serum biochemical, and cortisol changes associated with anticipation of exercise and short duration high-intensity exercise in sled dogs.

Background: Many studies have demonstrated changes in clinicopathologic variables in response to exercise in athletic dogs. These changes have been attributed to the duration and intensity of exercise. However, inconsistencies in the timing of collection of resting blood samples can be a confounding variable when interpreting results.
