Dogs can experience rapidly increasing breathlessness due to an injury to the chest or lungs. It is also possible to obstruct the airways, for example due to foreign bodies or swelling of the mucous membrane after a wasp sting. Accident dogs in particular should be watched carefully as they sometimes only show signs of deterioration after hours.
At first the dogs breathe hard with their lips pulled back and neck stretched out, the tongue can already take on a bluish tint. Breathing can be slow and strenuous as well as rapid and superficial. As soon as the breathing rate drops below 6 puffs per minute, it is imperative that you hurry.
If the dog is unconscious, lay it on its side, pull your tongue forward and try to remove any foreign objects that are obstructing the airway, for example with a spoon handle. Close your mouth with your hand and blow into your nostril until your chest rises. Then let the air escape again. Repeat this every 3 seconds, combined with cardiac massage every second in the case of cardiac arrest. Take the dog to the vet as soon as possible.
Avoid Accidents: Train your dog to be roadworthy and only walk on a leash near roads. Watch the dog carefully after a supposedly minor collision and see the vet at the first sign. Keep wasps and dangerous foreign objects away from your dog.
