In dogs, wheezing is a symptom which can be caused by upper respiratory problems, such as asthma, bacterial and viral infections, and more. This page looks at the possible causes of wheezing and noisy breathing in dogs, as well as things that you can do to prevent or soothe wheezing in your dog.
Wheezing refers to a whistling sound which can be heard sometimes when a dog breathes in and/or out.
In a healthy dog, the airways expand and contract rythmatically so that the right amount of oxygen is delivered to the lungs.
However, wheezing occurs when there is a problem with the airways - When the airways contract too much, oxygen has to squeeze its way through, resulting in a high-pitched sound. Thus, dog wheezing is a sign indicating some problems (usually spasm or narrowing) in the trachea or bronchi.
Below are some of the possible causes of dog wheezing.
Causes of Dog Wheezing
- Allergies: Many dogs wheeze when they have an allergic reaction to certain irritants, such as pollen, house dust, cigarette smoke, etc. Chemicals in pesticides or some kind of flea control products may also cause allergy-prone dogs to wheeze. Sometimes a dog can develop an allergic reaction to insect bites or stings. If your dog starts wheezing after being stung or bitten by an insect, take him to the vet immediately.
- Canine Respiratory Problems: Dogs suffering from respiratory problems such as asthma may also wheeze. Other common symptoms related to respiratory problems include coughing, sneezing, and gagging.
- Infections: Chronic sinus infections (e.g. caused by a root infection of the upper canine teeth) can cause wheezing. Viral or
bacterial infections (e.g. kennel cough) can also result in wheezing in dogs. If your dog suffers from kennel cough, he will also have a dry, hacking cough with gagging and retching.
- Parasites: Some parasites can cause dog wheezing. One such common parasite is the heartworm. When the heartworm larvae migrate to the dog's heart and develop into adult worms, they can block blood flow and consequently oxygen supply to different body organs, including the lungs, is reduced. This causes dog wheezing.
In addition to that, the dog also shows symptoms such as coughing, shortness of breath, fatigue and weight loss.
- Congenital Abnormality: Some breeds of dogs (such as pugs, bulldogs, shih tzus) whose muzzles are short often show some degree of airway
obstruction. This condition is known as brachycephalic syndrome and is manifested by mouth breathing, snoring, and snorting. Sometimes (especially when the dog is
exercing or is overheated), the dog may also wheeze.
- Other Health Problems: Other canine health problems that may cause wheezing include congestive heart failure, and tumors of the larynx,
trachea, and lungs.
When to See a Vet?
As you can see, there are quite a few possible causes of wheezing in dogs. If your dog has repeated bouts of wheezing, or if the wheezing lasts longer than 30 minutes, then it is advisable to take him to the vet for a check-up.
You should seek immediate veterinary attention if your dog shows the following symptoms in addition to wheezing:
- Appetite loss
- Chronic coughing
- Other respiratory problems (such as excessive panting and sneezing, shortness of breath, difficulty breathing)
- Gums that are bluish or pale in color
