This was a good game but you can't delete your profile (As far as I know I bought this last year but only kept it for a couple months. I'm in tight with GameStop trading) so I got stuck with a dang Yorkie, boxer, and a poodle. Also, during school I ask my mom to feed them and give them water, but she doesn't know how to even turn the dang DS on. (LOL!!!!!!) It is very good, but unless you know how to delete profiles, or want to be stuck with the last renter's dogs, I recommend dropping 20 to 30 bucks to get a fresh start, but if you want to try it first, go ahead. It is pretty much the same with the others (Different versions). The only reason the scores are different is because of the breeds of dogs. Worth buying more than renting, but go ahead and rent it, just to try it!
I'll admit that initially I was drawn in by the whole cute puppy thing, selecting and naming your very own unique Nintendog, teaching it tricks and whatnot. The competitions and bizarre item collecting (Pirate Hats, Scholar Glasses) gave me something to actually do with my new puppy, but the game gets old, I can only win so many disc competitions before I get bored, and the constant feeding, watering, bathing, walking, and "potty breaks" just wasn't doing it for me. Getting another dog helps for awhile but it's just prolonging the inevitable, eventually you just lose interest. Overall it's a decent title that may be good for younger kids but it's not going to win any awards.
