Neither both have teeth both can bite and both can cause the injury. Its not how bad its the fact that all dogs can bite and cause injury. The schnauzer biting me may not cause much injury as I can defend against it but when the schnauzer bite a child that can not defend his/her self then the injury obtained then would be greater. All dogs will bite and cause injury so all dogs should be considered dangerous in my book untill I feel safe around them. Thats all of my opion on this subject, no matter the dog if provoked they will bite any size any breed!!
