Most dog owners know to leave out fresh water — but during summer months, that's often not enough. Dogs can't sweat through their skin the way humans do; they regulate heat almost entirely through panting, which expels a significant amount of moisture with every breath. On a hot day, a large dog can lose more than a litre of water just from panting.
Dehydration in dogs is easy to miss until it's serious. Here's what to watch for, and how to make sure your dog is actually drinking enough.
Signs Your Dog May Be Dehydrated
- Dry or sticky gums — healthy gums should be moist and pink
- Skin tent test — gently pinch the skin at the back of the neck; if it doesn't spring back immediately, your dog may be dehydrated
- Lethargy or excessive panting at rest
- Sunken eyes or loss of appetite
- Dark yellow urine — pale yellow is the target
If you notice several of these signs together, contact your vet promptly. Severe dehydration is a medical emergency.
How Much Water Does a Dog Need?
A general guideline is approximately 1 ounce of water per pound of body weight per day — more during hot weather, after exercise, or if your dog eats dry kibble exclusively. A 60-lb dog should ideally be drinking around 60 oz (roughly 1.75 litres) daily in normal conditions, and more in summer.
Why Dogs Sometimes Refuse to Drink
Dogs are more likely to drink from clean, fresh, moving water. Standing water in a bowl that's been sitting out for hours — especially in the heat — can develop a stale taste or smell that puts dogs off. Some dogs are also sensitive to the taste of tap water if it's heavily chlorinated.
This is where a pet hydration station makes a genuine difference. Circulating water stays oxygenated, cooler, and more appealing. Many dogs that are reluctant drinkers from a standard bowl will drink significantly more from a fountain-style station.
The AutoRefresh Pet Hydration Station keeps water continuously circulating and filtered, so your dog always has access to fresh, clean water — even when you're away from home. It's one of the easiest changes you can make to meaningfully improve your dog's daily hydration.
Practical Tips for Summer Hydration
- Multiple water points — place water sources in every room your dog spends time in, plus outdoors in the shade
- Ice cubes — most dogs enjoy licking ice, and it's a simple way to supplement hydration on hot days
- Wet food or broth — mixing a small amount of low-sodium broth into dry food adds moisture and encourages eating and drinking
- Post-walk water — always offer water immediately after outdoor exercise, before your dog has fully cooled down
- Travel hydration — a portable folding bowl means your dog can drink on hikes, car trips, and days out without you needing to improvise
The Bottom Line
Hydration isn't a seasonal concern — it's a year-round one that becomes critical in summer. Building in a few simple habits and upgrading your water setup can make a measurable difference in your dog's energy, health, and comfort through the warmer months.
