Vitamins

• Kennel cough usually runs its course with no treatment between 1 to 3 weeks. Provide a high-quality canine vitamin to boost the dog's immune system.
  
  

Homeopathic Remedies

• Several homeopathic treatments for easing kennel cough symptoms are available at pet stores that specialize in natural treatments or at natural food stores with pet departments.
  
  

Humidifier

• A humidifier can help relieve the dog's coughing if the house is dry.
  
  

Steam Bath

• Additionally, treating the dog to a steam bath by letting him sit in a room where the shower is running a few times a day can help open bronchial passages.
  
  

When to Visit the Veterinarian

• If the dog becomes lethargic, loses its appetite or coughs up phlegm that isn't clear, a trip to the veterinarian is in order. The vet will likely prescribe an antibiotic if a secondary infection has developed.
