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.
When you have thalassemia, your body makes fewer red blood cells and less hemoglobin than normal. Hemoglobin is an iron-rich protein in red blood cells. It allows the red blood cells to carry oxygen from your lungs to the rest of your body. Having not enough red blood cell hemoglobin is anemia.
