My pack of small dogs do a pretty good job of alerting: toy poodle, minature poodle, and Yorkshire terrier. In training is our standard poodle pup bred out of royal poodle stock (extra large!) who should end up northward of eighty pounds. The little dogs are training him to alert to sounds. Won't be long and he'll have a big bark and a big bite!
