Only two or three people have actually answered my question. The purpose of this topic was to get a specific event in which your dog has had to hold for an exceptionally long period of time. I know that ideally a catch dog will hold until death. I like to read your hunting stories so that is why I posted this topic.
This topic really seems pointless. Your asking for something no one should do or know why they would do. Atleast I have no idea why someone would time how long a dog would catch. Aside from a few accidents and misfortunes like Joey or Kevin had....asking how long a catch dog can hold in a hunting situation is like playing russian roulette.
Anything over a few minutes is way too long. Although there are certain circumstances where a hog breaks or somethings happens and it is unavoidable.
Thanks Rex.
