Congrats! I have three dogs and couldn't imagine my life without them.
You're going to have a great time taking the puppy shopping with you. That's what we did with the last two we adopted, and it was so much fun! Once you have the dog, then you have an idea of what kind of collar looks best on them...important stuff, you know.
I think the most important thing is that you'll begin training the moment you step inside your door. If you don't want the puppy on your couch or bed, start training immediately...and be consistent. It's harder to break a bad habit after the fact.
I'm so happy for you! I love new furry babies!!!!
