As record-setting temperatures grip the nation, pet owners are increasingly concerned about the safety of their dogs during outdoor excursions. Experts recommend a multi-faceted approach to determine if a walk is safe and how to protect canine companions from heat-related illnesses.

Assessing the Heat Index

Veterinary experts advise checking the heat index, often referred to as the "real feel" or "feels like" temperature, rather than just the ambient air temperature. "Generally speaking, it is safe to walk a healthy, adult dog when the heat index is 85 degrees or lower," said Dr. Sarah Wooten, a veterinary expert with Pumpkin Pet Insurance. Humidity plays a significant role, meaning that in more humid areas, the acceptable temperature range for walks may be lower. Even in 90-degree weather, a leisurely walk on grass or dirt might be permissible if the humidity is low, but pavement and asphalt should be avoided.

Breed and Individual Considerations

The ability of a dog to tolerate heat varies significantly by breed, coat type, and overall health. Brachycephalic or "smush-face" breeds, such as bulldogs, have more difficulty regulating their body temperature and are at a higher risk. Similarly, dogs with thick coats, while potentially insulated against cold, can struggle in extreme heat. Very young, elderly, or dogs with pre-existing health conditions like heart disease, breathing problems, or obesity require extra caution.

Contrary to common assumptions, double-coated dogs, including Australian shepherds and golden retrievers, should not have their fur shaved. Their coats can offer protection from the sun and heat. Breeds like greyhounds may also be at an increased risk of heat distress.

Pavement and Hydration

Before venturing out, pet owners should test the surface temperature of pavement. Placing a bare hand on the ground for five to ten seconds can indicate if it is too hot for a dog's paws. If the surface feels too hot, it is best to postpone the walk or opt for a different location. While paw protection like dog boots can offer some barrier, it may not be sufficient if the ground temperature is excessively high.

Throughout any outdoor activity during hot weather, consistent hydration is crucial. Owners should carry ample water for their dogs and offer it frequently. Increasing a dog's fluid intake can also be achieved by adding water to their kibble or offering frozen treats like ice cubes made with low-sodium broth or water-rich fruits such as melon and berries.

Timing and Cooling Products

Strategic timing of walks is essential. Early morning or late evening, when temperatures are coolest and direct sun is less intense, are the safest times. Walks should be kept short, primarily for necessary bathroom breaks. Owners should encourage a leisurely pace, allowing dogs to sniff rather than covering long distances quickly.

Various cooling products can aid in temperature regulation. Cooling vests or bandanas, which can be soaked in cold water, provide evaporative cooling. Gel mats and beds offer a cool surface for dogs to rest on indoors. For a DIY approach, frozen water bottles wrapped in socks can be placed on the floor for dogs to lie beside.

Recognizing and Responding to Heat Distress

Owners must be vigilant for signs of heat exhaustion and heat stroke. Symptoms of heat exhaustion can include lagging behind, seeking shade, lying down, heavy panting, and increased thirst. If these signs appear, activity should cease immediately, the dog should be moved to a cool area, and water offered without force. Heat exhaustion can rapidly progress to heat stroke, characterized by high body temperature, rapid breathing, bright red gums, difficulty balancing, vomiting, excessive drooling, and lethargy or collapse.

In cases of suspected heat stroke, owners should apply cool, wet cloths to the dog's skin and seek immediate veterinary attention. As a preventative measure, owners can also offer cool treats such as frozen fruit, ice cubes, or frozen Kong toys filled with dog-safe ingredients like yogurt or pumpkin.
