Your dog is the best hiking buddy you'll ever have, as long as you pack for two. Start with a harness that fits your dog's build; Treeline Review's hiking-with-dogs guide likes one with a top grab handle for quick control when passing others.
Bring water just for them, in a bottle with a built-in bowl, and a small dog first aid kit sized for a daypack. A dog backpack is the fun nice-to-have that lets your pup carry their own water and treats. Treeline Review field-tests harnesses, packs, bottles and first aid kits, and every pick here comes from those reviews. Each card shows the drawback the testers called out, so you can match the gear to your dog's build.
Who this is not for. Skip this if your dog's adventures stay on the sidewalk; the Dog Walking Kit list has hands-free leashes, treat pouches and collar lights.
Tell me what you can spend. I pick a tier for every item, essentials first, and show what is left. The first amount covers everything you need at the cheapest tier.

A harness, a dog water bottle and a dog first aid kit are the essentials. A dog backpack is nice to have. Our Day Hiking list covers your own daypack, poles and shoes.
Treeline Review names the Ruffwear Flagline its best dog harness for hiking; it's highly adjustable and great for long dogs, though the neck isn't padded. For big dogs, its pick is the Ruffwear Web Master, and its hiking-with-dogs guide likes that harness's top grab handle.
It's optional and fun for day hikes. Treeline Review's best overall, the Ruffwear Approach, suits many dog builds, and it warns that its large-capacity pick makes it easy to overload your dog's pack, so start light.
