Hiking with your dog is one of the best ways to tire you both out. But dehydration is a real risk — dogs shed heat mostly by panting, which costs them water fast in warm weather and at altitude.
How Much Water Does Your Dog Need?
A rule of thumb often quoted is roughly one ounce of water per pound of body weight per day in normal conditions, and about double that on an active day. Treat it as a starting point, not a prescription: puppies, senior dogs, flat-faced breeds and dogs on medication all differ. Ask your vet what is right for your dog before a long or hot outing.
Signs of Dehydration on the Trail
- Heavy panting that does not settle down after a rest in the shade
- Dry, tacky gums — healthy gums feel wet and slippery
- Loss of skin elasticity — gently pinch the skin over the shoulders; it should fall back straight away
- Lethargy or refusing to keep walking
- Sunken-looking eyes
If you see these, stop, get into shade, and offer small amounts of water at a time. Any dog that will not drink, collapses, or vomits needs a vet, not another mile.
Gear That Makes It Easy
A Packable Bowl
The main reason people skip water breaks is faff. A collapsible silicone bowl weighs almost nothing and clips straight to a leash or pack strap. Roam Bark's Collapsible Travel Bowl folds flat to about 2 cm, comes with a carabiner clip, and has a 13 cm (5.1") rim — one size, sized for a drink stop or a single meal rather than a full day's food.
Carrying the Water Itself
For anything over an hour, carry your dog's water separately from your own so you always know how much is left. Do not plan on streams and puddles filling the gap.
Dog Backpacks
Bigger dogs can carry their own water once they are conditioned for it. Load light, keep the weight even on both sides, and build up over several outings rather than starting with a full pack.
Trail Habits That Help
- Start topped up — offer water about half an hour before you set off.
- Offer water every 15–20 minutes during moderate activity, even if your dog seems fine.
- Skip stagnant water — standing water can carry giardia and other parasites.
- Pack more than you think you need. Water is the one item nobody regrets carrying.
- Freeze a bottle the night before so you have cold water deep into a hot day.
Timing Beats Everything
In summer, walk early (before 10am) or late (after 4pm). Hot trail surfaces and pavement burn paw pads — press the back of your hand to the ground for seven seconds, and if you cannot hold it there, it is too hot for their feet.
Gear Up for the Next One
The Travel & Outdoor collection has the packable bowl and the rest of the trail gear. If you are starting from scratch, pair it with a no-pull harness and a rechargeable LED collar from Walking & Safety.
