Here are five common culprits of hair loss in dogs that should be discussed with your veterinarian. Allergies are a frequent cause of hair loss in dogs. This may due to environmental triggers such as pollen, molds and dust mites, or due to parasitic triggers like fleas or mites. Food allergies are another possible cause of hair loss.
Anemia, also spelled anaemia, is usually defined as a decrease in the amount of red blood cells (RBCs) or hemoglobin in the blood. It can also be defined as a lowered ability of the blood to carry oxygen.
High levels of abnormal white blood cells can cause anemia, tiredness, weight loss, bone pain and frequent infections. Most seriously, people with thick blood -- whether from excessive blood cells or hypercoagulation -- are at high risk for clots that block or limit blood flow to vital organs.
