Are the symptoms seasonal?
You might also consider certain herbs, such as Milk Thistle or Dandelion, which support the liver and help the body detoxify. There is also a group of autoimmune diseases called Pemphigus which cause scaly skin, scabs and pustules. Emotional upset? Thyroid imbalances may cause dull, flaky or greasy coat and sometimes hair loss. Fleas particularly love the areas at the base of the tail, ears and hind legs (where they meet the belly). These things can all give off chemicals which may cause illness. If you suspect your pet has fleas but you haven’t actually seen any, look for the tell-tale black “specks” at the base of the hairs. To determine if the specks are flea dirt (dried blood) and not just dirt, put some on a white paper or cloth and wet them. If you must bathe, use a gentle shampoo.
