Dog started opening after hogs break!?

Yes Waylon she does quiet down after they get away from her. I do feel like she is really close to them in the race when she is barking. I'm definately going to cull her I'll make her a brood bitch if it ever got that bad. She is one fine find dog. Not a whole lot of bottom a mile or two for her is it. But she strikes hard.

Not sure if anything has changed as far as environment. I don't think so but I'm going to have to think on that.

Another thing she is just gritty enough to get in ones face and make one break but not gritty enough to catch and hold so she may be getting frustrated on big hogs. I was advised to get a muzzle by an old timer buddy of mine. Any muzzle suggestions?
