Summer is the best season to get your dog out on the trail — and the one that catches the most owners out. Heat builds faster than you'd think, water hides risks that look like fun, and a dog who's perfect off-leash in the park can vanish over a ridge where your phone has no signal.
None of that should keep you home. A little planning turns a risky day into a great one. Here's how to hike with your dog safely this summer: beating the heat, handling water, keeping an off-leash dog findable, and what to throw in the pack before you go.
Quick Takeaways
- Hike early or late — avoid the midday heat, and test the trail surface with your hand before letting paws on it.
- Carry more water than you think you need, for both of you, and take shade breaks often.
- Water is fun but not risk-free: watch for currents, blue-green algae, and saltwater — and don't let a thirsty dog gulp it.
- Off-leash freedom is the whole point — but most trackers die where there's no cell signal. A radio-based GPS tracker keeps working off-grid.
- Pack a kit: water, bowl, lead, first-aid basics, tick remover, and a way to find your dog if they bolt.
Before you head out
A good hike starts at home. Match the trail to your dog's fitness — a puppy, a senior, or a flat-faced (brachycephalic) breed like a Bulldog or Pug can't handle the distance or heat a young Lab shrugs off. Build up mileage gradually rather than attempting a 10-miler on the first warm weekend.
Check three things before you commit: the weather (temperature and humidity, not just sunshine), the trail rules (is it dog-friendly, and is off-leash allowed?), and the terrain (shade, water sources, and how far you'll be from help or a phone signal).
Make sure vaccinations and flea/tick prevention are current — summer is peak tick season.
Beating the heat
Hike in the cool of early morning or evening, never the midday peak. Dogs cool themselves by panting, not sweating, so they overheat far faster than we do — and heatstroke can become life-threatening in minutes.
Two quick field tests save a lot of grief.
First, the seven-second rule: press the back of your hand to the trail surface for seven seconds — if it's too hot for you, it's too hot for paws, which can blister on sun-baked rock or sand.
Second, watch your dog, not the thermometer: heavy or frantic panting, drooling, bright-red gums, wobbliness or collapse are signs to stop, get into shade, and start cooling them with cool (not ice-cold) water on the belly and paws.
Know the danger signs. Excessive panting, glazed eyes, vomiting, stumbling or collapse can signal heatstroke — a genuine emergency. Cool your dog and get to a vet immediately. When in doubt, turn back; the trail will still be there tomorrow.
Bring more water than seems necessary and offer it at every break, plus a collapsible bowl. Take shade stops often, and on really hot days, simply pick a shadier, shorter route or save the hike for a cooler day.
Water & swimming safety
Lakes, rivers and the beach are the best part of a summer hike — but moving water, blue-green algae and saltwater all carry real risks. Let your dog cool off, just supervise it like you would a child.
A few things to keep an eye on: currents and cold water can tire even strong swimmers fast, so a canine life jacket is smart for rivers and open water; blue-green algae (cyanobacteria) blooms in warm, still water in summer and can be fatal if a dog drinks or licks it off their coat.
When in doubt, stay out; and at the coast, discourage gulping saltwater, which causes "beach diarrhoea" and, in volume, salt poisoning.
Always rinse off salt, sand and lake water afterward, and bring fresh drinking water so your dog isn't tempted to drink where they swim.
The good news for gear: your tracker shouldn't be the thing you worry about. The Aorkuler GPS Tracker 2 is IP67 waterproof, so river crossings, lake swims and rain are no problem — it keeps tracking through all of it, which matters most exactly when a wet, excited dog decides to follow a scent downstream.
Off-leash freedom without losing them
Off-leash is what makes a hike feel like freedom — for both of you. The catch: the moment your dog crests a ridge or drops into a valley with no cell signal, most GPS trackers go dark. A radio-based tracker keeps working where there's no coverage at all.
Only let your dog off-leash where it's allowed and where their recall is genuinely reliable — summer trails are full of wildlife, other dogs, and scents worth bolting after. Even the best-trained dog has an off day, and that's the scenario you plan for.
Here's where it pays to understand your gear. Most popular trackers (Tractive, Fi, and the like) send your dog's location over the cellular network — brilliant in town, useless on a remote trail the moment the bars disappear.
The Aorkuler GPS Tracker 2 works differently: the collar unit talks directly to a handheld controller over radio, showing live direction and distance up to 3.5 miles with no cell signal, no app and no subscription.
It's built for exactly the off-grid places summer hikes take you — and there's a sound-and-light beacon to help you close the last few feet through dense brush. If you want the full breakdown, see our guide to no-subscription dog GPS trackers.
Don't let a lost-signal moment turn a great hike into a frantic search.
Track your dog anywhere — no signal needed →What to pack for a summer hike
A simple kit covers most of what can go wrong. Build it once and keep it by the door:
- Plenty of fresh water + a collapsible bowl
- A sturdy lead (even if you'll go off-leash)
- GPS tracker that works without cell signal
- Canine life jacket for open or moving water
- Basic first-aid kit + a tick remover
- Paw balm or booties for hot/rough ground
- Poop bags (pack it out)
- A recent photo of your dog, just in case
Trail etiquette (and keeping it that way)
Shared trails stay dog-friendly when owners are considerate. Yield to hikers and horses, keep your dog from rushing strangers or wildlife, and always pack out waste. Stick to marked trails to protect both the habitat and your dog's paws — and respect leash rules even when no one's watching. Good behaviour is why these places stay open to dogs.
Frequently asked questions
What temperature is too hot to hike with a dog?
There's no single number — humidity, coat, age and fitness all matter — but once it's into the high 20s °C / 80s °F, take real care, and avoid the midday peak entirely. Flat-faced, very young, senior or thick-coated dogs struggle sooner. Hike early or late and use the seven-second paw test on the ground.
Can my dog drink from streams and lakes?
It's safest to bring your own water. Natural water can carry parasites like Giardia, and warm still water may contain toxic blue-green algae. Offer fresh water often so your dog isn't tempted to drink where they swim.
Will a GPS tracker work where there's no phone signal?
Most won't — cellular trackers need coverage to report a location. A radio-based tracker like the Aorkuler GPS Tracker 2 sends your dog's position straight to a handheld controller over radio, so it keeps working off-grid with no cell signal, app or subscription.
Is it safe to let my dog swim on a hike?
Usually yes, with supervision. Watch for currents and cold water (a canine life jacket helps), avoid water with visible algae blooms, discourage gulping saltwater at the beach, and rinse your dog off afterward. A waterproof (IP67) tracker means you don't have to take it off for water.
