A dog on a mountain trail is pure enthusiasm in its natural element – and a responsibility that starts long before the trailhead. Dogs don’t pace themselves, don’t read weather, and can’t tell you their paws are cut. The human carries the entire safety margin for two. With preparation, though, hiking with your dog is one of the great shared pleasures of mountain travel. Here is how to do it well.
Check the rules first
Not every trail welcomes dogs, and the rules are getting stricter, not looser. Many national parks restrict dogs – some ban them from trails entirely, others allow them on-leash on selected paths, and rules can change with seasons (nesting birds, lambing, hunting). Check the specific trail and the managing authority before you set off, not at the trailhead sign. Where dogs are allowed, leash laws and livestock-protection rules apply: in many mountain regions a dog worrying sheep can legally be shot by a farmer, which concentrates the mind wonderfully. Hiking only where dogs are welcome, and behaving impeccably there, is what keeps trails open to dogs.
Fitness, paws and heat
Dogs need conditioning just like people. Build mileage gradually over weeks; a dog that sprints the first hour and limps the last is a dog that was over-faced. Paws are the weak point on mountain terrain: sharp scree, ice and long rocky days cut pads, and hot ground burns them – test ground temperature with your own hand, because paws blister long before booted feet notice. Paw balm toughens pads, and booties are worth carrying for snow, ice or very rough ground – but train your dog to accept them at home first, not on the trail.
Heat is the bigger danger than cold for most dogs. They cool themselves by panting, which is inefficient at altitude and in still air. Offer water frequently and don’t wait until the dog looks thirsty. Learn the warning signs of overheating: heavy panting, drooling, glazed eyes, slowing down. A tongue turning purple is an emergency signal – cool the dog, rest in shade, and be ready to cut the day short. Short-nosed breeds and heavy-coated dogs are at particular risk and may simply not be mountain hikers in summer.
Water, food and what not to drink
Carry dedicated water for the dog plus a collapsible bowl, and budget more than you think – dogs at altitude drink a lot. Pack extra high-energy food; a hard day burns far more calories for a dog than a rest day. Discourage drinking from standing water: stagnant pools can harbour bacteria, parasites such as giardia, and – in warm weather – toxic blue-green algae blooms that can kill a dog. Flowing streams are generally safer, but carrying enough remains the reliable answer.
Gear that earns its place
The essentials: a well-fitted harness with a sturdy handle (for lifting over stiles and out of trouble), a reliable leash, a dog pack for fit adult dogs so they can carry their own food and water, booties, a coat for short-coated breeds in cold conditions or a cooling vest for heat, a first-aid kit (gauze, bandaging, antiseptic, tick tweezers, any regular medication), waste bags, and your vet’s phone number saved offline. Many experienced dog-hikers also carry an emergency carry-sling – if your dog is injured miles from the road, you are the evacuation plan.
Wildlife, livestock and other people
Keep your dog under control at all times: on a leash where required, and under genuinely reliable recall everywhere else – be honest about whether your recall is genuinely reliable. Don’t let dogs chase wildlife; a frightened deer can kill a dog with a kick, and encounters with skunks, porcupines or venomous snakes (a real hazard on some mountain trails) end badly for everyone. Give horses a wide berth and step aside with your dog while other hikers pass. Pack out all waste or bury it properly away from water, keep barking to a minimum, and leave every trail better than you found it. Dog owners are ambassadors on every trail they walk – one badly behaved dog can close a route for all of them. After the hike, do a full tick check: ears, neck, armpits, groin, between the toes. Then let your very tired, very happy dog sleep.
