Interesting timing for a thread on this.
I may have just adopted a stray today.
He's all white, wolfish looking, blue eyes, looks somewhat like a Husky, but doesn't have the curly tail.
He's trained, knows how to sit, collar but no tag. He's been wandering for quite a while based on being dirty and skinny, and seems a little hurt (slight limp)
Went to the store and got him food and some treats, and a 15' leash so he doesn't wander away.
Going to spend a bit looking for his owner, but if I can't find them I may just keep him. Wasn't quite ready to commit to a puppy and all that it entails, but if a good dog needs a home, I can provide that.
Boss likes him, so maybe he'll just come to work a lot. (If I can figure out how to fit him in the Boxster)
As far as the original topic, I've heard that Greyhounds are great dogs. A lot like big cats, lazier than you'd think for something that goes fast. One friend's even used to hide sometimes when it was time for a walk because it would have rather slept.
