Ok got a ?

I only have two male at my place. The Stag and my brindle mutt Tiger. Tiger is/was an instigator. I let all my dogs out every evening to run and such so they have to get along. The ole Stag put him in check several times (stag would catch ear/head just like a hog poor Tiger looks like a hog that has had multiple catch dogs on him). He still never quit his crap. I finally went and got me a "hot shot". Busted both of them with it the next fight then Tiger when he growled and once more when Tiger just looked crazy. Not a problem since. I'm sure I will have to use it again but for now everything is good and they completely avoid each other. Going on a month with no drama.
