Addisonian patients may present with lethargy, diarrhea, vomiting, increased thirst, increased urination, and unplanned weight loss. Intermittent shaking episodes are sometimes seen. The signs may wax and wane. Clinical signs of Addison's disease are usually vague and non-specific, meaning there are no particular signs that indicate a diagnosis of the disease. Sometimes this condition takes on a much more serious presentation resulting in sudden weakness, with severe vomiting and diarrhea, and sometimes collapse. If a pet experiences recurrent bouts of sudden lethargy, diarrhea and vomiting, increased thirst and urination or other non-specific illness, Addison's disease should be considered as an underlying cause.

Addison’s disease is known as “the great pretender” because its clinical signs can mimic those of many other diseases. The signs can wax and wane, or be vague and non-specific, and they can include any of the following: Lethargy, Loss of appetite, Vomiting, Diarrhea, Weight loss, Increased thirst and urination, Trembling, Weakness, Dehydration. Addison’s disease can also present as an acute medical emergency called an Addisonian crisis. An Addisonian crisis may appear as sudden weakness, severe vomiting, diarrhea and sometimes collapse. If your dog shows any of these signs, they need immediate veterinary care. The clinical signs may appear as vague signs of illness that come and go. However, if a dog’s hormone levels become critically low, Addison’s disease can become an acute and life-threatening condition.

The clinical signs are often vague and may be episodic; they include lethargy, anorexia, vomiting, weight loss and general weakness. Dogs may drink and urinate more. Unfortunately, these signs are not specific to Addison's disease and may also be noted in a variety of other diseases. Occasionally, dogs can experience an ‘Addisonian Crisis' and become suddenly seriously unwell.

Symptoms of Addison’s are often vague to begin with, but over time, tend to become more severe. Addison’s disease can be tricky to spot because it often causes vague symptoms that come and go. Contact your vet urgently if your dog is showing symptoms of an ‘Addisonian crisis’ - this is an emergency. Symptoms include those that have been waxing and waning over time. Left untreated, Addison’s disease is often fatal, but fortunately, with treatment, most dogs have a good outlook and can live a relatively normal life. It is important to have your dog checked regularly, and tell your vet about any new or changing symptoms.
