Getting a new dog is one of those moments where you think you're prepared and then realize pretty quickly that you were not. I've had Arie for three years and I still think about what I wish I'd set up before he came home. The right crate setup, the right gear on day one, a mealtime routine that actually works, and a game plan for when he inevitably decides your baseboards look delicious. This is the list I'd build if I were starting fresh tomorrow — organized by what you need to set up before they even walk through the door. Everything is on Amazon. Everything is Arie-approved through trial and error.
