Les hommes ont oublié cette vérité. Mais tu ne dois pas l'oublier, dit le renard. Tu deviens responsable pour toujours de ce que tu as apprivoisé.

Behaviour of deers chased by hunting dogs

Sweeney, J. R., Marchinton, R. L., & Sweeney, J. M. (1971). Responses of radio-monitored white-tailed deer chased by hunting dogs. The Journal of Wildlife Management, 35 (4): 707-716.

Studies were conducted on three separate areas-Auburn, Alabama; Eglin Air Force Base, Florida; and Savannah River Plant, South Carolina-to determine the responses of white-tailed deer (Odocoileus virginianus) to chasing by hunting dogs (Canis familiaris). Deer chosen for harassment were animals that had been studied by telemetry until normal behavior, movement patterns, and ranges were delineated. In every chase the deer escaped the hounds, and all deer remained in good physical condition throughout the study. Behavior that resulted in escape was classified into five categories: holding, distance running, circuitous zigzag running, separating from a group, and using escape habitat. Chases averaged 33 minutes in duration and 2.4 miles in distance with maximums of 155 minutes and 13.4 miles recorded. Deer in high populations were more difficult to chase for extended periods than those in low populations. Although the deer did not require water for escape, they usually selected swamps or other bodies of water when these were available. The deer could readily be chased out of their home ranges, but usually they returned in 1 day or sooner.
