I have no luck with female-female matches. Our first three dogs were males--two altered, one not. Never had a problem. The fourth was a female--again no problems. The fifth another female and all h@ll broke loose. Massive girl fights, huge vet bills, Kayleigh almost killed Sleet on one occasion. (all my girls are altered)

My males fight occasionally, but they fight different than the girls. The males stop when the other dog submits or they get whatever it was they wanted (toy, food ect) They rarely do any serious damage, usually nicked ears are the most serious injury. They posture lots, tons of noise and talking, but very little real fighting.

The girls fight to the death--even the submissive ones. I rarely intervene if the boys are having a tiff. I always break up a girl fight. They will not stop until the other dog is completely incapacitated. I keep all my females in seperate pens, where they each live peacefully and happily with several males. I will never again have this many females. (i have five right now)
