7. Excessive panting
Nearly everyone has seen a dog pant on a hot day. Dogs are unable to sweat, so in order to lower their body temperature, they pant instead. Dog owners should be familiar with the times of the year and the reasons that cause their canine companion to pant, so it should not be all that difficult to pick up on it when it is occurring at an unusual time. It’s also important to notice if your dog is panting more loudly than normal or seems to be working extra hard at it. It’s a smart idea to check with a veterinarian if you notice any of those symptoms. Excessive panting can sometimes be a sign that your dog may have anemia, lung disease, laryngeal paralysis, Cushing’s disease or even heart failure.
