I considered a BRT before I got my Giant Schnauzer. Very intense. They do not do well with heat, I had a friend in Montana with 10 of them. He did not think they would do well with the small dogs (generally speaking) that I have. I did not find them to be as wiling or eager to work as a Dobie or German Shepherds Dog. My Giant is a peculiar worker but she's a superb guardian. He loves his BRTs but told me he misses his German Shepherds who would just comply rather than question.
