Steroids are a class of drugs that can be very helpful in treating a variety of diseases and conditions in dogs. Some steroids will reduce inflammation and at higher doses, they can suppress the immune system. This helps in post-surgical treatment, manage the effects of allergies and treat immune diseases and even some cancers. Steroids can also be used to stimulate the production of naturally occurring steroids that may have dropped off and are causing medical issues with your dog. Other steroids will stimulate appetite, increase strength and allow for weight gain as needed. Steroid hormones work with reproductive conditions and problems. These drugs can be very helpful when used for specific conditions under the guidance of a medical professional and with extreme care. Your dog may experience increased thirst, hunger and urination while on steroids. Watch for infections, muscular weakness and abnormal behavior.
