well if you already have the dog, use it
if you really want the dog, get it then use it
Honestly im not a coyote dog expert, I dont even own a coyote dog, Ive had bird dogs/beagles/staffs and mutts
But the way it sounds, and what alot of back and forth has been lately, if you train it well enough to suit you it should work fine.
Doesnt sound like any specific breed is bred for that, look at the guys dogs on this form, most are a mix of this, a little of that until they get what they want, or at least close, some tend to be more breed specific than others.
Heck ive been kicking around the dog idea for a few years now and still cant decide on a breed or type yet, one day im just gonna grab one, and give it a go.
I say go for it, what the heck, you wont know until you try it, kinda like pickled herring.
If anything you could use it as a catch dog on partridge

Good luck!
