Greyhounds kinda just stand there. They might be a little disappointing to a person who might want to play fetch, or play anything. I guess if you got a puppy you could teach it to be more like a dog, but rescue greyhounds are not very dog like. They are more like statues that need some care.

Autumn is definately almost as driven as a border collie, though not as intense. She loves to work. She's never competed in anything or been an actual working dog, but I've taught her since she was little all the commands to hunt and retrieve, herd, search, do agility, play frisbee, expert obedience stuff, and so on. She lives to learn and to "work". Her joints are bad so I don't let her exercise too much now, but she still needs a job. She brings in the paper and the mail. Just the other day I forgot to give her the mail when I was walking in, so she came up in front of me and stared at the mail in my hand until I gave it to her. Then she wagged her tail as fast as she could as she brought it the rest of the way inside.

I think a lab is a bad idea. 10 hours a day alone = house destroyed. Unless its an older dog of course. They've fallen into the "lets get a lab" trap because labs are so easy to come by and everybody has one.
