Symptoms

• Although ongoing scratching may be a sign of fleas, it can also signal that allergies may be a problem. If you notice that your pooch seems itchy all the time, is chewing on his feet and has hair loss in small areas, it's likely that atopic allergies are the problem.
  
  

Diagnosing

• Like humans, dogs often have seasonal allergies, so take note as to when allergic symptoms tend to occur to see if there's any pattern. If you are unsure whether or not your dog has allergies, it's a good idea to see your vet. Blood and intradermal skin testing are two ways to determine what allergies your pet has.
  
  

Triggers

• Dogs can be allergic to many things. Some of the typical offenders are flea bites, tree and grass pollens, foods, dust mites and certain materials.
  
  

Natural Treatments

• For itchy dermatitis, wash your dog with a hypoallergenic shampoo once every other week. Supplements such as omega 3 oils are known to reduce inflammation, and can be given orally as a tablet to help with itchy allergic reactions.
  
  

Medical Treatments

• In severe cases of atopic allergies, antihistamines or steroids may be prescribed. Because both come with side effects, they should only be given in cases of chronic allergies.
