Dog Medical Emergencies Survey: Is Severe Lethargy an Emergency?

The results regarding this one really scare me. Only 63.64% of the survey participants checked severe lethargy as an emergency.



And that is with the qualifier "severe" included, listed after reduced activity. No one single situation included in the survey got 100% votes for being an emergency, even though some of them are indeed as dire as it gets.

I explained the difference between reduced activity and lethargy in my last post. Reduced activity does require medical attention, but it is not an emergency.

Lethargy, particularly severe, most definitely, absolutely is an emergency.


While it is a very non-specific symptom, it is a major red flag. Dogs love life and live every moment to the fullest. Imagine how terribly a dog must feel not to want to get up and do anything at all! The more severe the lethargy, the more urgent it is to get your dog medical care.

What conditions can result in lethargy? Pretty much anything that can make your dog feel ill enough.

  • Trauma
  • Poisoning
  • Pain
  • Infections
  • Hypoglycemia (low blood sugar)
  • Anemia or other blood disorders
  • Heart disease
  • Respiratory conditions
  • Liver disease
  • Diabetes mellitus
  • Hypothyroidism
  • Addison’s disease
  • Cancer
  • Certain medications
  • Snake bites
  • Parasites
  • Dehydration
  • Hypothermia 
  • Gastrointestinal problems
  • Urinary tract problems
  • Electrolyte abnormalities
  • Immune diseases 
  • Neurological and neuromuscular disorders
  • Certain eye diseases
  • Musculoskeletal diseases

The more severe is the lethargy, the more serious is the problem causing it.


For example, severe internal bleeding, whether caused by trauma, bleeding splenic tumor or clotting disorder will result in severe lethargy. Do you think there is a more fitting example of an emergency than that? What about poisoning? Or severe hypoglycemia? Or liver failure? Severe infection or sepsis?

A recumbent, severely lethargic dog, could be a dying dog!


Add to that the fact that you have no way of discerning between your dog being unwilling or UNABLE to get up. A dog unwilling to get up is likely in severe pain. The reasons for being unable to get up are even worse.

Why am I trying to scare you? Because with a severely lethargic dog you should be scared. And on your way to a veterinarian.
