dogs are great friends, but i hope you are prepared for the responsibility. They are not toys or tools that you can put on the shelf when you are tired. They are living beings that you bring into your home and family. They can cost you as much as $50 a month in the long run. They need care too. Don't stretch yourself too thin.
I'm not trying to discourage, just inform. You are bringing another life, and everything that comes with it, into the mix.
