I agree with not trying to cross a bay dog on something in hopes of making high percentage catch dogs... but there are good lines of cur dogs over here that are known for being straight catch... what they lack, in my opinion, is size.... that's where I want to bring in a Dogo or other larger breed that would complement the cur dog and vice versa... bring the big dog's size down a bit, add to athleticism... maintain hardness...
An example... My Shine dog(my lead "bay dog"), both her mother and father were used as walk in catch dogs as well as strike dogs... both VISE GRIP hard... and I mean hard... If I wasn't worried about birthing complications I'd cross Shine with an athletic Dogo and I'd be set... Shine moves through a briar patch like a damn rabbit... a quality that most CD's lack...
How big are your CD's(I mean Krystal's CD's
) Doggie? They're straight Dogo right?
