It's just an opinion, but do what you want and feed what works. What most people get annoyed about is people trying to reinventing the wheel. People cross dogs all the time. Find the best you can, with the best qualities that you want filled. The ones that don't qualify, must be culled. Not given away, not sold, just culled. It's just when people ask for opinions on here, some or both parties get offended. I can't figure out why, some answer the way they do but that's life I guess. I'm not telling you what to do at all, I am just trying to give you some advise and insight.
Thanks,
Coach
I agree with Coach on the reinventing the wheel deal. That's what I see your friends trying to do. The things they are asking have been accomplished already by other people long ago who are now dead. When you cross dogs the offspring are inconsistent, then you have to keep crossing to mix and match to try and get this and that. If you stick with one breed you get more consistency and can predict what you get. You have to start with good stock though and that includes catch dogs.
Another thing you said, that your friends like the way their dogs work, if they did they wouldn't be looking to cross to another breed. Their actions suggest that they are "not" satisfied which is why they want to cross out to another breed. Why go through all that extra work?
That's why I suggested to use good abs, because people before us ran into the same problems and solved it already. Abs encompass the ability to catch, wind for hogs, and can be used to run along with curdogs loose as well even in hot weather and they are big enough and tough enough to stop big rank hogs. I know b/c my dogs do it and they produce dogs that do it.
