Dogs aren’t proficient at sweating like humans are, and that makes them much more prone to overheating. Tony Hawkins, Valley Vet Supply Technical Services Veterinarian, says overweight, older, or out-of-shape dogs, or dogs with underlying health conditions, may be at greater risk than healthier dogs. Dogs suffering from heat stress may demonstrate excessive panting, difficulty breathing, vomiting, and diarrhea. At that point, it’s critical that the animal gets veterinary care. Tips to keep dogs safe include never leaving dogs in parked cars that are turned off. In just 25 minutes, a car on a 73-degree day can reach 100 degrees inside. Also, plan those farm activities dogs can tag along for, such as checking fences, during the cooler times of the day. Hawkins says dogs aren’t good at stopping themselves when they get hot and just run themselves until they get overheated. Also, clip those dogs with long hair coats.
