Zoe my golden retriver of 6 is funny when people come in the house, it doesn't matter if she has known you her whole life or it's the first time. Her tail starts wagging uncontrolable, then she picks up the nearest object to her (remotes, shoes, toys, socks, ect) and whines through it kinda like a yodal. She dies to be pet. Stu my weiner dog hides till he fells it's safe, then comes and hides in my lap, he is about 4 months old so I hope he just hides instead of barking like a wild beast!
