A dog backpack for hiking is not for carrying your dog all day. It is for being able to carry it when you need to: a rocky section, a puppy that does not yet have the stamina, an old dog that tires on the way back, a scorching trail in midsummer. Seen that way, the criteria change completely.
When it is useful – and when it is a bad idea
Carrying your dog makes sense in four cases: a puppy whose joints cannot yet handle long distances, an older or recovering dog, a small dog whose legs take three times as many steps as yours, and difficult sections – scree, ladders, rope bridges, hot ground.
On the other hand, a healthy adult dog does not need to be carried on a normal trail: it needs to walk. The backpack is a back-up and comfort tool, not a default means of transport.
Weight: your limit comes before the backpack's
The rule is the same as in town: beyond about ten kilos, back carrying cannot be sustained for long. But on a hike, you have to add what you are already carrying – water, clothes, a picnic. An 8 kg dog plus 4 kg of gear means 12 kg on your shoulders for several hours, with climbs.
Be honest about the real distance you will cover with that load. If your dog weighs more than 10 kg, plan short outings, or a wheeled model for tracks suitable for wheels: see large dog transport.
A ventilated back: the criterion that matters most outdoors
This is the real difference between a city backpack and a hiking backpack, and it is rarely highlighted.
In town, the backpack touches your back for a few minutes. On a trail, it stays there for hours – and your body heat adds to the dog's. A flat back pressed against you turns the inside into an oven. Look for a padded back panel with air channels, or better still, a structure that lifts the backpack slightly away from your back.
And check that ventilation is spread over several sides, not concentrated on a single front window. In summer, a model with a large side mesh panel is better than one with a full bubble window.
Straps, on a hike more than anywhere else
The chest strap is essential from 6 to 7 kg. It keeps the load against your back instead of letting it pull away – which, going downhill, makes the difference between walking and catching yourself.
The hip belt becomes genuinely useful after an hour of walking: it transfers part of the weight to your hips, exactly as on a classic hiking pack. It is what lets you last the day.
Add side compression straps if the model has them: they stop the dog swinging from side to side with every step, which is exhausting for you and unpleasant for it.
Heat, the real danger of a backpack in summer
A dog does not sweat like we do: it regulates its temperature by panting. In a closed, poorly ventilated space exposed to the sun, it loses its main way of cooling down.
A few simple rules: avoid the hottest hours, walk in the shade whenever you can, and never leave the backpack closed in the sun during a break. Watch for excessive panting, heavy drooling and a very red tongue: these are the first signs of heatstroke, and you must then take the dog out, get it into the shade and cool it down gradually.
A full plastic shell, very pretty in photos, is the worst choice at 30 °C.
Water and breaks
Bring water for two, and a collapsible bowl. A dog being carried drinks less of its own accord than a dog that is walking: it is up to you to think of it, roughly every hour.
Use every break to take it out of the backpack, even for five minutes. Staying in the same position for hours makes it stiff, and letting it stretch its legs prevents tension on the way back. Harness and lead on before opening, every time: a dog that spots a deer is gone before you have realised.
What to check before you set off
- The interior dimensions compared with the length of the dog measured standing: it must be able to turn around and lie down.
- A ventilated back on the wearer's side, and ventilation on several sides for the dog.
- A chest strap, and a hip belt for walks of more than an hour.
- A firm base: on a soft base, the dog slides with every step going downhill.
- An internal leash clip to attach the harness before each opening.
- An easy-to-reach pocket for water, the collapsible bowl and the first-aid kit.
When you get back: two checks that take two minutes
Ticks. Run your hand through the coat, paying particular attention to the neck, ears, groin and between the toes. A carried dog still goes through long grass at the start and finish.
Paw pads. Look for cuts, grass seeds and burn marks if the ground was hot. That is often where the real tiredness of an outing shows.
Frequently asked questions
How do you choose a dog backpack for hiking?
On three criteria, in this order: interior dimensions suited to your dog, a ventilated back on the wearer's side, and a chest strap – plus a hip belt if you walk for more than an hour.
Which backpack for a walk with a small dog?
For a short outing, a light mesh model is enough. Only after an hour of walking do the straps and ventilated back become decisive.
How long can a dog stay in the backpack?
About an hour between breaks, less in hot weather. The important thing is to take it out regularly so it can stretch.
Can you go hiking with a puppy?
Yes, over short distances and carrying it for most of the route: its joints are still fragile. That is actually the use where the backpack is most justified.
