Pee in their water?

She's half catahoula half black mouth cur. She's chained out like the rest of my dogs. She will come to me and stuff she trusts me enough I suppose but when I call her she comes and crouches at my feet and tucks her tail. Hell I guess she really ain't all that skittish now that I think about it, just a little timid and real real submissive. She's about 14 months old. Got her from my uncle, he got a real heavy hand with her and did that dog in for him atleast. Told me to come get it or he was gonna shoot it. She's come around a lot. Just wish she had some confidence in herself rather than roll over almost scared at my feet. Working wise she done good. Bayed about 30 head of cattle for me when I first got her and she's seen one hog so far and bayed like crazy. I do plan on giving her a hell of a shot because she comes from real good bloodlines from what my uncle says. I know well enough that he don't keep junk
