I don't know if I've already posted here or not. lol.
Anyway, it all really depends on the actuall dog as far as energy goes. Yorkies are supposedly very hyper dogs, but Dixie's never been very hyper. She's active in that she likes to play with us, but as soon as we dont' want to play anymore, or we just want to relax, she's right there sleeping on our laps. Somedays we'll go on hikes up in our woods, and Dixie will be right there with us, but some days, we'll just sit around all day watching TV, and still Dixie's right there with us. She does what we do. She's an excellent dog. We also have a Silky Terrier mix who's a great dog, but she's alot more active than Dixie. We also have a Shih-Tzu who is probably the most laid back dog we have. She likes to go outside, and run around, but after a little while she's laying in the grass by our feet panting, and ready to go inside. If you want a non-shedder then I wouldn't reccomend a Shih-Tzu though. I asked before I got a Shih-Tzu if they shed or not, and I was told they do not, but Zoey definately sheds. Not a whole lot, but definately a lot more than our other 2 dogs. They don't shed at all. The only time any hair comes off of them is when you're brushing them. Good luck finding a dog!!!!
Neopit: Poodles of course are non shedding, but I can't think of any other non shedding big dogs except crosses.
