We have done PP training. Had to stop with my last two dogs because of the economy, but am hoping to get my stuff straight and go back in spring. We paid on a weekly basis. I was taking 3 dogs for OB every week, and 1 was doing PP training after the OB. I think the total was $60 every week? He offered a monthly plan, but I was nervous that due to my husbands schedule we couldn't make it out every week (there were a few weeks we had to skip) so it was better for me to do the weekly plan. Presas generally do not excel at Sch. It is designed for a herder more then a molosser, and they have a little trouble with things that emphasize the herder trait. Biggest problem I've heard of (and experienced) is the hold and bark part. A lot of presas get very serious when they step on the field- and they also get QUIET. My girl would bark herself hoarse on the sidelines or in the truck, but when we stepped on the field, you couldn't get her to make a sound for nothing. It took us WEEKS to get her to bark at the decoy instead of just biting him LOL. This also seems to be the same problem a lot of the few people training for Sch have. There are currently only about 10 KNOWN presas titled in Sch- only 1 has ever reached Sch II level. You can find a few more title holders here: http://dogocanarioclub.us/forum/index.php?topic=2021.0
