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.

What causes muscle atrophy in dogs head?
Many times myositis or inflammation of the muscle can cause atrophy of the muscles. Myositis is caused by an abnormal reaction of your dog’s immune system against the muscles. This can happen to only one muscle or to a group of muscles.
“MMM generally responds initially to therapy, but relapses occur quickly if treatment is discontinued prematurely.” “If the disease is diagnosed early and a dog is treated appropriately, the prognosis is good for dogs with MMM,” Greenfield says. “In these cases, dogs can usually regain normal jaw mobility and function.
