Causes

• Rashes can be caused by food, drug or environmental allergies. These rashes are typically itchy, dry areas on the skin.
  
  Parasites such as worms, ticks, lice and fleas can also be the culprits. Rashes are sometimes considered to be symptoms of serious types of skin problems that can be life-threatening in puppies.
  
  A rash caused by parasites can cause itching, redness and hair loss.
  
  

Immune System

• A compromised immune system can be the reason behind eczema, scalp psoriasis, ringworm, yeast infection, mange and/or dermatitis. In addition, to rashes, these disorders can also cause scabs, dry skin and hair loss.
  
  

Home Remedies

• Natural remedies offer alternatives to prescribed medications. Milk of magnesia can be squirted on a cotton ball and applied to the skin, for example. Another effective treatment is aloe vera gel or cream, which is considered to be a natural soothing restorative. Baking soda mixed with water and rubbed on the rash can help quell itching.
  
  A spray made from tea tree oil can be applied to the dog as well. This oil has a bitter taste and can help keep the dog from chewing on its skin and fur. An apple cider vinegar mixture can be used for the same purpose.
  
  

Bath Treatments

• An oatmeal shampoo that contains aloe can be beneficial. The aloe is a healing agent for the skin, while the oatmeal will help maintain the dog's coat.
  Commercial flea dips are also helpful for parasitic infestations, though dog owners should use caution when using these products due to the toxic chemicals they contain.
  
  

Treatment and Prevention

• Daily grooming is key in order to stay on top of possible parasites that can lead to other skin infections. Do not bathe your dog with shampoo too often because it can change the ph level of the skin and reduce natural oils. Nutritional meals aid in strengthening the dog's immune system and will help to keep skin problems under control.
