dex/depo injections

Question
Can these injections be harmful to a dog with heart problems?

Answer
I think that it would depend on the heart problem, but they are cortical-steroids and in large doses they could potentially be harmful to any organ in the body.

For short term issues and in small doses they don't seem to cause issues. Now if the dog has congestive heart failure it is NOT recommended.

"Who should not take it?
Not for use in animals with systemic fungal infections, some types of mange (mites), stomach ulcers, Cushing's disease, high blood pressure, kidney disease, or congestive heart failure. Do not use in pregnant animals. It may cause premature birth and birth defects in some animals. Depo-Medrol may stunt growth if used in young, growing animals or is given to nursing mothers."
