buckhunter I can tell you for a fact that yes a deer will get tired, but a dog will, as my uncle who hunted with dogs his whole life used to say "bust his heart" before they would ever catch a deer. A dog has no where near the stamina or speed a deer has, during buck season many moons ago I watched 3 doe that the dogs were running take a 5 minute break waiting for the dogs to catch up, then they got up and trotted on off, about 4 or 5 minutes later the dogs showed up tongues hanging! A deer can run circles around a dog all day long, the only thing the dogs do is get them moving, and there are no swamps where we ran dogs, as a matter of fact it was so flat that it is shotgun only and has been for over 40 years.
