Home remedies for dog cough include honey, probiotics, cough syrup and cinnamon, according to The Doggington Post. These remedies work as antibacterial and antiviral agents, offer immune system support and soothe sore throats.
Although kennel cough often resolves without treatment, a dog owner can use various home remedies to quicken his companion's recovery. Honey contains antibacterial properties that relieve sore throats, and probiotics clear bad bacteria from the system and boost immunity. Decongestant cough syrups make the cough productive, eliminating phlegm. Pet owners can sprinkle coconut oil and cinnamon, which contain antiviral properties, on dogs' food to combat the virus that causes coughing, states Dogster.
