How Much Water Does My Dog Need
Water is the most essential nutrient your dog needs — more important than food, vitamins, or any supplement. Yet most dog owners underestimate how much their dog actually needs to drink, especially during exercise, hot weather, or travel. This guide breaks down exactly how much water your dog needs and how to make sure they're getting it, wherever you are.
How Much Water Does a Dog Need Per Day?
The general rule is simple: dogs need approximately 60ml of water per kilogram of body weight per day. Here's what that looks like in practice:
How Much Water Does My Dog Need
- 5 kg dog (small breed): ~300ml per day (about 1.25 cups)
- 10 kg dog (medium-small): ~600ml per day (about 2.5 cups)
- 20 kg dog (medium): ~1,200ml per day (about 5 cups)
- 35 kg dog (large breed): ~2,100ml per day (about 8.75 cups)
- 50 kg dog (giant breed): ~3,000ml per day (about 12.5 cups)
Keep in mind this is a baseline for a resting dog in a temperate environment. Active dogs, nursing mothers, dogs in hot weather, or dogs eating dry kibble (which contains little moisture) will need significantly more.
Factors That Increase Your Dog's Water Needs
Exercise and Activity Level
A dog on a moderate hike can need 2–3 times their normal daily water intake. The harder and longer the activity, the more water they need. A working dog or a dog running alongside a bike may need even more. As a rule on the trail: offer water every 20–30 minutes, not just when your dog seems thirsty.How Much Water Does My Dog Need
Hot Weather
Dogs regulate body temperature primarily through panting, which causes rapid water loss. In summer, increase your dog's water availability significantly — always have a bowl out in shaded areas and carry extra water on outdoor excursions.How Much Water Does My Dog Need
Diet
Dogs eating dry kibble get very little moisture from their food (kibble is only ~10% water). Dogs eating wet or raw food get a significant portion of their daily water from meals. If your dog eats dry food, fresh water access is even more critical.
Health Conditions
Dogs with kidney disease, diabetes, or urinary tract issues often need more water. If your dog is drinking dramatically more or less than usual, consult your vet.
Signs Your Dog Is Dehydrated
Dehydration in dogs can escalate quickly, especially during exercise. Watch for these warning signs:
- Dry or sticky gums: Healthy gums should be moist and slippery. Dry or tacky gums are a red flag.
- Skin tenting: Gently pinch the skin at the back of your dog's neck. It should spring back immediately. If it stays tented, your dog may be dehydrated.
- Sunken eyes: Eyes that look dull or sunken indicate significant dehydration.
- Lethargy or weakness: A suddenly tired or reluctant dog on a trail may be dehydrated, not just tired.
- Excessive panting: Some panting is normal, but heavy sustained panting combined with other signs warrants immediate water and rest.
If you suspect serious dehydration, stop all activity, offer water in small amounts, and contact a vet.
How to Encourage Your Dog to Drink More Water
Some dogs are reluctant drinkers — especially away from home where the water tastes different. Here's how to help:
- Bring water from home: Some dogs won't drink unfamiliar-tasting water. Filling a bottle from your tap before a trip can help.
- Offer water frequently: Don't wait for your dog to ask. Build water stops into every walk and hike.
- Use a clean bowl: Dogs can be put off by dirty or smelly bowls. A silicone travel bowl that rinses clean easily encourages drinking.
- Add a splash of low-sodium broth: If your dog is being stubborn about drinking, a little chicken or bone broth in the water can make it irresistible.
- Wet their food: Adding water to kibble at mealtime is an easy way to boost daily intake.
The Best Way to Keep Your Dog Hydrated on the Go
The biggest barrier to proper dog hydration during travel and outdoor activity is convenience. If getting water out is a hassle, it doesn't happen as often as it should.
A collapsible silicone dog bowl solves this completely. It clips to your bag or leash, unfolds in seconds, and holds enough water for a proper drink — not just a few laps. At the end of a stop, it collapses flat and goes back on your pack without fuss.
At Dog Co, our foldable silicone travel bowls are designed for exactly this kind of on-the-go hydration. Lightweight, food-grade silicone, easy to clean, and available in colours you'll actually want to carry.
