I agree if you don't have the time or want to put in the effort for more than an hour a day don't get a dog.
Get a gameboy and buy the virtual dog game. And even in that your dog can die so you have to look after it on that to.
But it is better to try out with a animated one before going to a live one.
Do yourself and the dog a favour don't get one till you can spend more time with it.
