Koko, is not a watchdog but she will bark if someone she doesn't know drives up. We have a very large front porch where she spends a lot of time both during the day and evening. It has a gate to keep her from roaming. The UPS man, meter readers and Mailman do not get so much as a woof when they drive up. She usually stands up on the gate, tail wagging, to greet them. She has never shown aggression to people so if the burglar spoke to her she would probably stop barking and greet him with wags. I feel very safe with her around because she will always bark at unknown sounds. If I was being attacked I believe she would defend me. A Pit bull attacked me in my yard once and to my surprise she tore into him like a guard dog. He quickly left my property with his tail between his legs. This same PIT was later put down by authorities for killing a neighbors pet goats.
