Excessive Panting in Dogs


Excessive panting in dogs can be caused by a number of different factors - it might be due to heat exhaustion, heatstroke or due to the symptoms of an underlying illness, disease or undiagnosed health problem. Unlike humans dogs do not have sweat glands so are not able to perspire (sweat) to cool themselves down. Consequently a dog will start panting to enable his blood vessels in the mouth to cool and therefore start cooling the head ad surrounding area.


There are a variety of causes of excessive panting in dogs with some breeds more susceptible than others. For example short snub breeds are more likely to over heat or start to pant - these breeds which include Pugs, Pekingese and Bulldogs are referred to as brachycephalic breeds. The main reason for this excessive panting is due to this type of breed having a short nasel cavity with a short muzzle causing them to be more prone to getting hot which can further be exacerbated by obesity.

It is also worth mentioning that after giving birth a female is far more prone to panting this is due to their uterus becoming contracted after giving birth.

What are the main causes of excessive panting in dogs...?

1. Canine conjestive heart failure can cause your dog to pant more than usual. This is due to the diseased heart also starting to affect other organs inside your dog. You might notice that your dog starts to pant more after exercise as more strain is put on your dog's heart. Heartworm is one cause of this condition - if you have any concerns then you should take your dog to the vet immediately.

2. You might notice that your dog pants if he or she is in pain - dogs often pant when they have experienced trauma, are suffering from pain or are experiencing shock.
