When I go inworld after RL work in the evening, I usually am greeted by our dog "Mig" Mig is our Australian Shephard. Mig will bark and try to get my attention when I come home. He is so cool. I try to spend time with him playing fetch. Yes, he can even fetch.
Mig came from the Virtual Kennel Club. If you are looking for a great dog I recommend that you take a visit. More info is on the website.
Just as a side note, the creator is going to be attending SLCC in San Francisco in August.
