I do like PSA more than IPO , just personal preference but I won't lie , is not easy with a mollosoid breed , i would be happy for PSA -1 with a presa canario , hammer ( half brother to nakam ) is in training for his psa-1 this year.
I have not kept up with IPO training. I’m sure it has evolved since then. But I haven’t had any interest. The only reason for would be just to earn a title. So far it hasn’t motivated to look into it.
