an old pitbull conditioning trick is to look at your dogs toungue. if their tongue is rollled back while panting they are at a breaking point and they are truly gassed(this is when i call it or give them a break). if they are just panting hard but their tongue is out flat and not rolled back they are winded but they are okay.
thats good to know
no problem...test it out...if you look at a lot of these pics of the catchdogs after the catch(not all but some) you will see the catch dog sitting with their tongue rolled back. normally you have to wait 5-10min before you can move on cause that dog is flat whooped. then look at your bay dogs they can run all day and that tongue will be out flat but they will still tear off when they hit a hot track or if they bay dogs have been run real bad by a hog that tongue will roll back and they will be up your butt for 5-10min then when that tongue goes back flat they will get to hunting again.
