First time dog owner...please help!?

Well, you should first leave Lola in her crate when you leave(as ling as it's not too long because they need to use the bathroom and all that)....but after you've had her for a while, and if she behaves well, try letting her out of her crate when you leave. Also, it's best to let her out while you there for fresh air, but also keep her in, both I'd better. About her sleeping, let her sleep when she feels she wants to, but mostly she will/should sleep @ night around when you do. I suggest walking her every day!! Even If it's only a few minutes. Or play fetch it something to get her moving.I also suggest try not to let her eat table scraps, because between that and her normal food, she will become overweight and with that her back legs will become authretic. Hope it helps!! Enjoy your dog, they are amazing animals!! ;)
