144 Irocubabe, if you could shoot me a PM on who you use(d), I am moving to the outskirts of FOrney, closer to Terrell and Mesquite. My dog is already OB trained and I am just expanding on developing his PP skills more(he is PP trained already). Thanks!! They need to have “off breed” experience….my dog is Toro, the Dogo Argentino you see in one of Mike’s videos.
