5. Always ask dog owners for permission before approaching.
Like people, pups' personalities vary very widely. Some love making new canine friends. Others are more wary. The person who'd be able to advice you best is the owner. Even if Spot is friendly, ask before approaching to make sure the encounter doesn't escalate to aggression.
Depending on the length of your hike, you might want to bring along some snacks as well. Dogs should be kept hydrated and happy. Bringing your own water also saves you the headache of finding a water source and purifying it. If your dog seems especially tired, maybe it's time for a water break.
7. Just in case, bring a first-aid kit.
It doesn't have to be extensive, just some essentials, including gauze pads, antiseptic and bandaging in case your pooch gets hurt.
8. Always, always pick up after your dog.
Your four-legged friend has business to do, and it's your business to pick it up. Or you can bury it - just keep it away from the trail and water sources.
