Leave the water bowl where your dog can get to it easily. Since dogs can knock over the bowl while they’re drinking, use one that’s made to not tip and spill.
The weather can directly affect your dog’s water needs. Hot summer days, especially if your dog is going for a walk or playing outside when it’s hot, will increase your dog’s water needs, doubling and even tripling the amount. A hot summer wind can dehydrate your dog, too.
A pet’s instinct tells them that running water is fresh water, but stagnant water (like in a bowl) is not always safe or healthy. Many pets are naturally drawn to running water and will drink more from a fountain than they will from a traditional water dish.
