Best ways to keep your pet hydrated in summer
Practical strategies to keep pets hydrated in summer, from water station hacks to recognizing the early signs of heat exhaustion before it becomes an emergency.
Ensure constant access to fresh, cool water and add wet food to their diet, while monitoring for subtle signs of dehydration like tacky gums. This requires more than just a full bowl; it demands a shift in how you manage their environment and intake during high heat.
Water availability must be absolute
The simplest solution is often the most neglected: multiple water stations. A single bowl in the kitchen becomes a bottleneck if the dog is in the garden or the living room. Place bowls in every room they frequent, including shaded outdoor areas, to eliminate the need for them to travel far when thirsty. The water itself should be refreshed daily, as heat accelerates bacterial growth and makes the water unappealing.
Cooling the water can also increase intake. Dogs are less likely to drink tepid water on a 30°C day. Adding a few ice cubes to their bowl or using a slow-drip fountain can encourage them to drink more frequently. The sound of running water triggers a natural instinct in many animals to investigate and consume, making fountains a superior choice to static bowls for some pets.
Dietary water is a hidden source
Most owners overlook the water content in food. Dry kibble contains only about 10% moisture, whereas high-quality wet food or fresh diets can contain 70% to 80%. Switching to a wet food diet or adding a splash of water or low-sodium bone broth to their kibble is an effective way to boost hydration without relying solely on drinking behavior. This is particularly useful for cats, who often have a low thirst drive and may not drink enough to compensate for dry food.
For dogs that are picky drinkers, freezing portions of wet food or broth into ice cubes offers a dual benefit: a treat and hydration. As they lick the melting cube, they consume water slowly, which is safer than gulping large amounts of cold water that might cause stomach upset.
Environmental cooling reduces water loss
Dehydration is often a symptom of overheating. If a pet is struggling to regulate its body temperature, it will pant heavily, losing significant moisture through evaporation from the lungs and tongue. Reducing the ambient temperature lowers the need for this evaporative cooling. Use fans, close blinds during the hottest part of the day, or provide access to cool tiles or damp towels for them to lie on.
Short-nosed breeds, such as pugs and bulldogs, are at significantly higher risk because their anatomy limits their ability to pant efficiently. For these animals, cooling mats and air conditioning are not luxuries; they are essential safety equipment. Avoid exercise during the peak heat hours entirely, as the physical exertion combined with high humidity can lead to rapid fluid loss and heat stroke.
Recognizing the early warning signs
Owners often mistake dehydration for simple tiredness. The most reliable physical check is the gum test: healthy gums are pink and slick, while dehydrated gums feel sticky or tacky to the touch. You can also perform a skin tent test by gently pinching the skin at the scruff of the neck; if it snaps back slowly or stays tented, the animal is dehydrated. Other signs include sunken eyes, loss of skin elasticity, and excessive panting that does not resolve with rest.
If a pet shows signs of heat exhaustion, such as bright red gums, vomiting, collapse, or confusion, this is a medical emergency. Do not wait to see if they recover. Immediate cooling with cool (not ice-cold) water and a trip to the veterinarian is required. Heat stroke can cause organ failure within hours, and the window for effective intervention is narrow.
Special considerations for cats
Cats are notoriously poor at signaling thirst, often hiding symptoms until they are critically ill. In summer, this risk is amplified because they are less likely to drink from a bowl that has been sitting in a warm room. Ensure their water sources are in cool, quiet locations away from their food, as cats instinctively avoid water near their prey. Consider multiple water stations around the house, as cats may prefer different locations at different times of the day.
For cats that refuse to drink, the wet food strategy is non-negotiable during hot spells. If a cat stops eating or drinking, or shows lethargy, a vet visit is urgent, as feline hepatic lipidosis can develop rapidly if they do not eat for just a few days.
Hydration in summer is about proactive management rather than reactive fixes. By adjusting water availability, dietary intake, and the living environment, you can significantly reduce the risk of heat-related illness. The goal is to prevent the condition before the first sign of distress appears.
