sorry that video is so misleading on the info they share , we got 21 presas from small pups to 14 year old veterans, and yes is not a breed for all people but is the most loyal breed that a family can own , you need set boundaries as the dog need training but once both owners and dogs make that bond and respect each other, they are a great stable animals to live and work with. ( just my two cents ). also future owners need to search for a stable stock, strong but stable.
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.
