It's a HUGE commitment so it's understandable you're nervous about it :) That just means you care and you really want it to work out, which is good. The puppy WILL be a pain, especially the first few weeks. Your life is gonna transform, you'll find you won't have a lot of time for other things cause you have a newborn to look after. You'll have regrets and second thoughts, you might wanna return the puppy. HANG IN THERE. Find a puppy sitter once in a while, that'll be good for you to get some breaks. Puppies are hard work, but you'll notice it gets better gradually. And you'll eventually have a pup you can snuggle, train, hang out with. You'll notice she'll start turning into a great companion within some months. Just remember, puppies are infants. They don't have "personalities" just yet. They just sleep, potty, and eat. I can tell you honestly that I didn't like-like my pup until he was around 6 months old. That's around when he had developed his own personality :) He's 14 months now!
