The real fast version ta get ya started.
Dogo: Catch
The rest: Bay. Depending on grit.
Show them youngsters a smaller hog and see first if they will bay before ya go anyfurther. If no luck after multiple attempts check out the culling posts on here for the correct method of fixing that problem.

That should at least get ya started with em. Find out what ya got before you waste alot of time and money.
No matter what breed or name attached to the breed..dont make excuses for em...just cull and try again if they dont cut mustard for ya.
The catch dog boys can prob get ya started on your Dogo.
Good luck bud. Welcome to doggin!
