Cushing’s Disease in Dogs

our bull dog has cushing disease? we need help.also she has low thyroid. Thanks jackie

Hi Jackie,

Cushing’s Disease or Syndrome is a hormonal disorder in which the dog produces too much cortisol, the stress hormone produced in a “fight or flight” situation. Often your dog’s symptoms are unusual skin growths and a “flea bitten” look to the coat. Left untreated your dog’s prognosis is not good.

There are two kinds: one is caused by a tumor on the pituitary gland, a small very important gland deep in the brain which controls the adrenal glands that produce cortisol as well as the thyroid gland and all hormonal functions of the body; the other (rare) is caused by a tumor on the adrenal glands causing it to produce more cortisol.

Your vet can do blood tests to determine which kind of Cushing’s your Bulldog has. Cushing’s is controlled with medication that supresses the production of cortisol. You will need to do follow up blood tests regularly to make sure the medication levels are appropriate.

Since your Bulldog has low thyroid the cause of his hormonal disorder is most likely from a problem with the pituitary gland. This is manageable but she will need medication for the remainder of her life.

Here’s an article from the FDA with more information: Cushing’s Disease in Dogs
