It's an interesting cross breed as both breeds are loving, intellegent, and affectionate. The Bichons tend to be naturally sociable while Schnauzers can be fiesty. Hopefully this mix will help tame the agressive nature of the Schnauzer.
When people talk of hybrid puppies, they usually claim that in a cross-breed you get the best of both breeds. The cynic in me often wonders why you can't just get the bad traits of both parents? According to dogbreedinfo.com, "the percentage of designer dogs with genetic problems is much lower then purebred dogs because the gene pool is mixed. "
Like purchasing any dog, it is important to visit with the dog and try to see what temperments they have. Know and understand the common temperments of both breeds, because in a hybrid dog, you can get any combination of those traits.
