  Allergies can be caused by seasonal environmental afflictions in the form of pollen, grass, plant fibers, trees or insects. Allergies also can be caused by mold, dust mites, human dander or cigarette smoke.
  
  

Symptoms

• Nasal allergies in dogs typically affect both sides of the nasal passages. There will be noticeable sneezing and discharge from the nostrils. Blood or pus is not common for nasal allergies. It usually does not affect the demeanor of the dog and it is able to carry on with a normal schedule of drinking, eating and basic activity.
  
  

Treatment

• The first means of action is to seek advice from your vet, as corticosteroids may need to be prescribed. The most effective means of treatment is to separate the source of the allergen from the dog. If possible, eliminate the source of the allergen altogether. Washing the dog's bedding and play toys in hot water on a weekly basis can be helpful. Keep the dog off of upholstered funiture as well.
  
  

Moisture Control

• Mold can thrive in indoor environments that have high humidiy levels, leading to nasal allergy symptoms. Try to find an outlet for lowering the moisture level, such as a dehumidifier. If the source of allergies is outdoors, try to keep the dog indoors as much as possible during the day. Allergens such as pollen are at the highest levels from noon through late afternoon.
  
  

Dust Control

• Because house dust can accrue throughout the week, vacuuming the carpets at least twice a week can be effective in removing allergens. The cleaning of air ducts in heating and air conditioning units also can be an aid in limiting fungi in homes.
