Any cut or break in skin can lead to an infection. Skin infections may also be caused by other, underlying problems such as allergies. Skin infections are usually not life threatening but need to be treated. First aid is a great step to relieve basic problems but a vet may be needed for further treatment. Some common skin problems are: Bacterial Infection - red bumps/pimples, scabs, redness, flaky skin, patchy coat Demodex - circular or patchy hair loss, bald patches with red-gray skin around the eyes and muzzle, swelling of feet Ringworm - crusty circular area of hair loss on face and then front legs Scabies- itching hair loss, crusty skin, rancid odor, scaling Seborrhea - greasy, smelly coat, and thick dandruff Yeast - redness, dandruff, itchy skin, greasy coat, rancid odor
