Hiking with your dog in the UK: rules, paw care and route planning
· Updated
Hiking with your dog in the UK comes down to two things: keeping the dog under effective control as the law requires, and reading the ground and the weather so the walk stays safe for their body. Get those right and your dog is the best trail companion there is.
The single rule that catches people out is the lead. On Open Access land you must keep your dog on a lead around livestock all year, and on a lead everywhere between 1 March and 31 July to protect ground-nesting birds, whether or not there are animals in sight. Everything else on this page builds on that.
This is part of our guide to camping with your dog, from Camping Sites in Britain, where you can find and compare dog-friendly campsites, caravan parks and glamping across the UK.
The Countryside Code rules for dogs
The law is clear and the fines are real, so learn these before you set off. The Countryside Code sets out what "under effective control" means in practice, and the rules tighten on Open Access land, the mapped moor, heath, down and common you can roam across.
| Situation | What you must do |
|---|---|
| Anywhere in the countryside | Keep your dog under effective control: on a lead, or close by and certain to return on command |
| Near livestock, on any land | Put your dog on a lead. It is good practice everywhere and a legal duty on Open Access land and the coast |
| Open Access land, 1 March to 31 July | Keep your dog on a lead of no more than two metres, even with no livestock about, to protect ground-nesting birds |
| Cattle chase you | Let the dog off the lead. Do not risk getting hurt trying to protect it |
| Anywhere your dog fouls | Bag it and bin it in any public waste bin, or take it home |
That last rule about cattle looks like a contradiction and it is the most important one to remember. Cows see a dog as a predator and will chase it, and a dog on a short lead drags a frightened herd straight onto you. If a herd moves at you, drop the lead, let the dog go, and take the quickest route out. The dog will outrun the cattle and both of you are safer apart.
Always clean up after your dog. Dog mess spreads illness to livestock and wildlife and there is no version of "away from the path" that makes it acceptable. Carry more bags than you think you need and a sealable pouch to hold them until the next bin.
You can read the full rules on the Countryside Code page on gov.uk. Scotland has its own guidance under the Scottish Outdoor Access Code, with the same principle of keeping dogs away from livestock and ground-nesting birds.
Fitness and paw care
Build your dog up to the distance the same way you would train yourself. A dog that pootles round the block every day is not ready for a 15-mile day on rough ground, and pushing an unfit or very young dog too far damages developing joints. Add distance gradually over a few weeks, and check with your vet before big days if your dog is a puppy, elderly, or a flat-faced breed like a bulldog or pug that struggles with exertion and heat.
Paws take a beating on stone, scree and hot ground that soft grass never prepares them for. Toughen the pads with regular walks on varied surfaces, keep the fur between the toes trimmed so grit and grass seeds cannot lodge there, and check every pad at rest stops for cuts, splits or trapped debris. Carry a self-adhesive bandage and a spare bootie in case a pad tears miles from the car.
Grass seeds are a summer menace on UK trails. The arrow-shaped seeds work into paws, ears and eyes and can burrow under the skin, so check between the toes and around the ears after any walk through long dry grass. The right kit makes all of this easier, and our guide to the best dog hiking gear covers harnesses, boots, collapsible bowls and first aid.
Heat and water
Dogs overheat far faster than we do because they cannot sweat, and heatstroke kills dogs on British hills every summer. On warm days walk early or late, stick to shaded and higher routes, and turn back rather than push on if your dog is lagging. Heavy panting, drooling, wobbliness, bright red gums or collapse are an emergency: cool the dog with water, get them into shade, and call a vet at once.
Carry more water than you expect to use and offer it at every stop, because dogs will keep going long past the point they should have drunk. A collapsible bowl weighs almost nothing. Do not rely on streams and puddles: standing water can carry blue-green algae, which is toxic and often fatal to dogs, so keep them out of scummy or discoloured ponds and lochs entirely.
Tarmac and bare rock hold heat brutally. If you cannot hold the back of your hand on the surface for seven seconds, it is too hot for paws, so time road sections for the cool of the day.
Ticks and adders
Ticks are the routine hazard and adders the rare one, and both are worth knowing before you walk in long grass, bracken or heath. Check your dog for ticks every evening, running your hands over the body and paying attention to the ears, armpits, groin and between the toes. Remove any you find with a tick tool or fine-tipped tweezers, gripping close to the skin and pulling straight out without twisting. Ask your vet about a tick treatment if you walk regularly in tick country like the Highlands, the Lake District or the New Forest.
The adder is Britain's only venomous snake, found on heathland, moorland, dunes and woodland edges, most often basking on warm spring and summer mornings. Adders are shy and strike only when trodden on or disturbed, but dogs get bitten far more often than people because they nose into the undergrowth. A bitten dog needs an emergency vet immediately: carry them if you can rather than letting them walk, keep them calm, and do not try to treat the bite yourself. Keeping to the path on known adder ground during the basking hours is the best prevention.
Planning a dog-friendly route
Plan the route around the dog, not just the view. Check before you go whether dogs are allowed and whether the ground suits yours: some nature reserves and beaches ban dogs in the bird-nesting season, some fell routes cross open moor where the 1 March to 31 July lead rule applies for the whole walk, and stiles, ladder styles and long stretches of livestock fields make hard work for a big or nervous dog.
- Match the distance and terrain to your dog's fitness, age and breed, and always have a shorter escape option
- Know where the water is and where you will need to carry your own, and avoid routes with no shade on hot days
- Read the access rules for the specific land: Open Access moor, National Trust ground and farmland all differ, and lambing season brings extra restrictions
- Fit a collar with an ID tag showing your name and phone number, which is a legal requirement in public, and microchip details kept up to date
- Pack the dog's own kit: lead, spare lead, water, bowl, poo bags, a towel, and a basic first aid kit with a tick tool and bandage
The same skills carry over to other trail sports, so if you ride as well as walk, our guide to mountain biking with your dog covers pace and control on shared trails. When you are ready to base a whole trip around walking with your dog, browse our dog-friendly campsite listings to find a site with trails from the gate, and Scotland is especially good for it, as our roundup of dog-friendly camping sites in Scotland shows.
Frequently asked questions
Do dogs have to be on a lead when hiking in the UK?
Not everywhere, but you must keep your dog under effective control at all times. On Open Access land you must use a lead around livestock all year, and a lead of no more than two metres between 1 March and 31 July to protect ground-nesting birds, regardless of livestock.
What should I do if cattle chase me and my dog?
Let the dog off the lead immediately and take the quickest route to safety. Cattle chase the dog, not you, and a dog let loose will outrun them. Never try to protect or carry your dog, and do not keep it on the lead near you.
How far can a dog hike in a day?
It depends entirely on breed, age and fitness. A fit adult dog built up gradually can manage 15 miles or more, while puppies, older dogs and flat-faced breeds need much less. Build distance slowly over weeks and always carry a shorter option.
How do I keep my dog safe from ticks on a walk?
Check your dog all over every evening, especially ears, armpits, groin and between the toes, and remove any ticks with a tick tool, pulling straight out. Use a vet-recommended tick treatment if you walk often in the Highlands, Lake District or New Forest.
Can my dog drink from streams and puddles while hiking?
Carry your own water and offer it often rather than relying on the trail. Standing water can contain blue-green algae, which is toxic and often fatal to dogs, so keep them out of scummy or discoloured ponds, and do not let a hot dog gulp cold water fast.
When is dog fouling allowed to be left on a trail?
Never. Always bag your dog's mess and put it in any public waste bin or take it home. Dog waste spreads disease to livestock and wildlife, and leaving it, bagged or not, is both antisocial and against the Countryside Code.
The short version
Keep your dog under effective control, on a lead around livestock and on Open Access land from 1 March to 31 July, and let it off if cattle chase you. Build fitness slowly, protect the paws, carry water, check for ticks, and plan the route around your dog rather than the view.
Do that and hiking together is brilliant. When you want a base with proper walking on the doorstep, start with our guide to camping with your dog or browse the campsite listings.
