Veterinarians provide dogs with cortisone injections, most often, when the pet is in a constant state of itching and scratching. The cause of this discomfort is most often an allergic reaction. Cortisone injections are also a common treatment for relieving pain in arthritic dogs.

Purpose
-
The allergic reaction that is causing the dog to scratch is a malfunction of the body's defenses. The cortisone suppresses the defenses, causing the itching to go away. Cortisone also reduces inflammation, making it helpful for dogs with arthritis.
Function
-
Cortisone creates an anti-inflammatory effect similar to that of cortisol, which is a hormone produce by the body. The anti-inflammatory property is helpful in reducing inflammation and is the main reason it is given to arthritic pets.
Time Frame
-
Cortisone will remain in the dog's system from 8 to 12 weeks after the injection. However, the dog may begin itching again--or experiencing pain associated with arthritis--as the levels of cortisone decrease, but are still present in her system.
Side Effects
-
Cortisone causes increased thirst and increased urination in most dogs. It may also cause increased appetite, depression, hyperactivity, panting and diarrhea in many dogs.
Long-Term Effects
-
Cortisone affects the dog's liver, pancreas and adrenal glands. It also suppresses the dog's immune system.
