A productive cough in dogs may be an indicator of the kennel cough, but also a more advanced infection. The productive cough is defined as the cough after which the dog expectorates mucus or other types of discharges; the productive type of cough is opposed to the dry cough, which will not result in any discharges.
Causes of Productive Cough in Dogs
The productive cough in dogs may have various causes such as:
Bacterial or viral infections
The kennel cough, which is a common bacterial respiratory infection; the infection may be contracted from other pets that carry the bacteria and if your dog has been in a kennel, he is very likely to have caught the infection from this environment
Pneumonia, which may originate in an infection that has advanced to the lungs
Internal parasites may cause this type of cough; heartworms or lungworms may be suspected
Lung problems
Heart problems
An allergic reaction to mold, chemicals, dust or pollens
The productive cough may also appear after the dog starts a treatment with certain drugs that are used for a dry cough. In this case, the productive cough will indicate that the infection is about to heal.
The symptoms that may accompany the productive cough may include:
Difficulty breathing
The dog may cough up blood
Wheezing
Watery eyes
Nasal discharges, that may vary in color and consistency
Resistance to exercise
Depression and lethargy
Not all these symptoms will be present; the presence of the symptoms will be determined by the condition that affects the dog. However, some dogs may not have any additional symptoms.
Diagnosing Productive Cough in Dogs
The diagnosis of the cough in dogs will be made based on the symptoms reported and a set of additional lab tests. It’s important to let your vet know for how long the cough has been present and whether the cough was dry in the beginning.
The lab tests that may be performed may include:
Blood tests, which can reveal the presence of a bacterial or viral infection, but may also show if there are antibodies that are produced when the dog has heartworms or lungworms
X-rays to see if the lungs or the heart is affected
Ultrasounds to detect any tumors or abnormalities
A test of the discharge, which can identify the infectious agents
Treatment Options for the Problem Causing the Cough
The treatment options for a productive cough will vary, according to the diagnosis and the dog’s overall condition:
Antibiotics, used for viral and bacterial infections, including the kennel cough
Antitussives, which will eliminate the cough and may be applied in conjunction with antibiotics
Steam baths, which can clear the air ways and are recommended if the dog ahs an infection
Heartworm medication, but this won’t be effective if the infection is in an advanced stage
Surgery, for serious lung or heart problems
Antihistamines or steroid medication for an allergic reaction.
