Dogs can develop productive coughs that help clear mucus, bacteria and debris from their airways or can be plagued with unproductive coughs that resemble a dry, persistent hacking. Both types of canine coughing cause throat soreness, discomfort and sleeping problems that may be alleviated with suppressants.
Dogs can develop coughs from conditions including: kennel cough, viral, bacterial and fungal infections, tuberculosis, roundworm and heartworm and through exposure to environmental allergens such as mold, dust and pollen.
Coughing may be accompanied by symptoms of fever, malaise, runny nose, sneezing, wheezing, watery eyes, decreased energy levels and appetite changes. Canine coughs and related symptoms are treatable with homeopathic and traditional suppressants that help relieve symptoms by reducing lung inflammation that causes breathing difficulty and pain.
Human over-the-counter cough suppressants are effective in treating a dog's chronic coughing. Children's cough syrup can be added to dog food every six hours in a recommended dosage based on a dog's weight.
Homeopathic suppressants such as ingesting honey-soaked bread and sleeping with a humidifier or vaporizer emitting eucalyptus oil or Vicks VapoRub into the air can provide moisture and reduce cough-promoting inflammation by coating a dog's throat and opening the airways.
Dog coughs related to allergies can be suppressed with over-the-counter or prescription oral antihistamines, suppressants and corticosteroids, while coughs that continue to worsen after four to five days may indicate a serious condition beyond the common cold, requiring veterinary consultation and treatment through antibiotics and immunizations.
