Catch dog stopped catching?

To say a catch dog has only one job is to sell it way way short or misunderstand them. If all you want is a dog that you lead up to a pig and turn it loose to catch what's just a few yards beyond it and catch or die trying and that's as far as your understanding essentially goes with catch dogs or that's your only criteria, great. However catch dogs are the most versatile hog dog there is. They can do it all. If a lead in is as far as you want to take a catch dogs job, and you dont have much patentience in developing a dog, then a pit is definitely a go to dog for this type of person . However even they are capable of much more than just that.
Though it's not the culture of most here in the US, catch dogs are performing every role every dog in your kennel combined does. (Exception - I don't know of any that willfully grind out a cold track the way some hounds do) The realm of catch dogs can get pretty complicated and complex because of the wide range of roles some are expected to perform by their owners.
Some of the combined jobs a catch dog is to perform on each hunt is to strike it's own pig be it off the truck, casting, or hunting out on the ground while your driving, and also hunt equally well by sight and by sound. These dogs are to have very good stamina and heat tolorance. Their holding style must be clean. When the hunter takes possession of the pig, the catch dog is to role out and hunt up another. The objective is to catch the biggest pig available running past smaller pigs to catch a bigger one or running past a dog that's already caught in order to grab ones own. They need to be very fast when performing to this degree. Afterwards they take in the role as loyal companion and family / pack member. Sometimes as alarm bells when unannounced quests show up or other critters show up that may prey upon the chickens. They are stock broke and wildlife broke except for the intended species such as wild pig. Should be able to hunt on an exotic high fence game ranch without showing interest in any other animal other than pig. They are expected to be able to do all this and more without the help of another dog.
This is what the line of dogs I run are bred to do and this is what I expect from all but 1 of my dogs. To get this degree of catch dog you don't need the line of dogs I keep, you can pretty well get most of this with most breeds of catch dogs used but when wanting the complete package, it's better to go to a line of these dogs rather than hope for a pit that can combine the stamina, heat tolorance, speed, and clean hiding style with what you can bring out in the dog such as everything else. To get this level of catch dog, you can not just be content with the one job and one job only outlook.
It amazes me that people will put this amount of effort, training, patience and research into their bay dogs that can only take the hunt half way and must be completed by the catch dog, when the catch dogs are very capable of performing the entire steps from beginning to end, by themselves. I think people for different reasons don't see catch dogs as being able to do these things as I've described. They either don't have the patience and understanding of them or are intimidated with the thought of working to this degree with a catch dog they see as dumb or stubborn or unteachable, they don't understand how to hunt without bay dogs, they think a catch dog is not capable of hunting and striking pigs as well as their lead strike dog, they want catch dogs catching now and not tomorrow etc.
Some guys just partial to listening to dogs bark and running pigs.
Either way, what I'm trying to say is catch dogs can be more than just catch dogs if you don't limit yourself and them by saying they only have the one job. Some guys may be wanting more out of their catch dog than just the one thing. For these guys, they will need a better understand of what it takes to develop a catch dog to do these things rather than the guys that see and use their catch dogs as just lead in catch dogs.
