A ventilatory pattern of the pet characterized by rapid, shallow breathing. Panting is normal in dogs and some cats, especially when they are hot or playing hard. However, when dogs and cats display abnormally heavy panting, they very well may be in distress. Some of the most common causes of excessive panting in pets include heat stroke, poisoning, pain and anxiety. Other causes of heavy panting are heart problems, respiratory disorders, various medications and Cushing\\\'s syndrome.
How to Recognize
When dogs are panting, they will breathe with their mouths open and make relatively quick and loud noises while they breathe. Dogs\\\' tongues will usually hang out as they pant.
Dogs will pant when they are over-excited or hot, but owners should be wary of an underlying condition. Heavy panting can be a sign that a pet is suffering from heatstroke, intense pain, or an underlying respiratory or heart condition.
You should provide your pet with water when they start to pant and move him or her to a cool area. If your pet continues to pant, bring him/her to your vet. If there is a respiratory or heart condition, your vet will be able to treat your pet accordingly.
