Catch dog stopped catching?

This is my opinion and strictly that, a catch dog is the navy seal of your pack, he's never supposed to question his job and never once be out of the fight until he takes his last breath, every single time out no matter the circumstance, my advice would be to make him a pet and move on if your attached to him, folks can church it up however they want but a dog who doesn't do his job when he's asked to do it is a cull, no different than a man in the work force, if you pay a man to weld and all he does it tack then he ain't a welder and he gets fired and is replaced with a welder. I don't have the time to put a lot of time into trying to make a catch dog, some say I'm a little harsh but after a dog catches the first time if he ever questions his job then he no longer resides on this earth, I hunt by myself a good bit and need a dog I can depend on when called upon, not one I've seen back down before, that will always be in the back of my mind every time I hunt.
