Too Much Steroid in the Body

In this case, steroid refers specifically to corticosteroids. These are hormones naturally produced in a dog’s adrenal gland to regulate many metabolic functions. We also have synthetic corticosteroid medications prescribed to treat inflammation and immune-mediated disease.

One of the possible side effects of steroid medication in dogs is muscle wasting. Some dogs are very sensitive to steroid treatment and develop marked symptoms including weakness and shrinkage of their muscles. You’ll usually notice this the most over the top part of a dog’s body–the skull, spine and pelvis become more prominent and the muscles over them shrink.

Another way a dog can have too many steroids in their body is from Cushing’s disease (hyperadrenocorticism). This condition produces way too much cortisol due to a tumor in the pituitary gland or on the adrenal gland. The symptoms are the same as if the dog was taking synthetic steroids: weight gain, muscle wasting, increased thirst and appetite, pot-belly and panting.

It’s not unusual for a dog taking steroid medicines like prednisone or a dog with Cushing’s disease to have a bony head.

Open fontanelles are holes in the skull that result from incomplete closures of the skull’s soft spots during normal growth in puppies.

Is masticatory myositis fatal in dogs?

Masticatory myositis can be fatal as the dog cannot open its mouth to eat or drink properly. If the disease goes untreated or it has progressed to the point that most of the muscle fibers of the jaw have been replaced by fibrous tissue, this disease is not curable.
