Thanks for all the feedback!
I’ve been around enough Catahoula’s to realize there are really good ones and really bad ones but there typically isn’t any middle ground. She appears to be one of the really good ones.
She is absolutely not dog aggressive so I’m not too concerned between her and the JRT. The JRT is about the most laid back JRT ever and we have a zero tolerance for a hog dog that shows any dog aggression, the sport is dangerous enough that if the dogs aren’t focused on their job it’s too easy for people to get injured.
My main concern is the cats, like many of you have pointed out. It may be over stimulating for her. (however I’m hoping that because she’s been trained to only hunt hogs that she won’t pay them too much attention. She will not trash on deer, coons, possums, armadillos, etc) I do have a fenced in yard and do not leave the dog(s) inside when I’m not inside. The JRT was raised with cats and absolutely adores her cats but she’s still a JRT and is a hunting machine outside, I trust her about 90% but I don’t ever give her that 10% opportunity. The prospective new dog would be heavily supervised inside.
