Aggression in dogs can have a medical basis. Medicine-induced assault can cause growls, clicks, tooth showings, and body positioning in a dominant position. Medical causes of aggression in dogs include hypothyroidism, hypoglycemia, and inflammation of the brain.
Brain inflammation that occurs in conditions such as encephalitis is one of the most serious medical causes of aggression in dogs. Anger and mombus are two types of viral encephalitis. In cases of brain inflammation due to diseases such as encephalitis, assault is usually a neurological reaction to the effect of inflammation on the brain.
Hypoglycemia, or hypoglycemia, is another possible cause of aggression and may or may not be related to diabetes. Dogs with hypoglycemia may feel disoriented and weird. If they feel vulnerable, they can behave aggressively to avoid looking weak. Dogs with hypoglycemia may have glass eyes and look. Weakness or collapse can occur. A veterinarian can do a simple blood test to diagnose hypoglycemia.
Hypothyroidism is one of the most common medical causes of aggression in dogs. Very low thyroid levels affect mood. Thyroid replacement therapy has been helpful in relieving aggression in dogs with hypothyroidism in some cases. Other symptoms of hypothyroidism are weight gain, lethargy, and loss of a large amount of hair.
More than 50 different breeds and crosses are susceptible to hypothyroidism, and it is one of the most studied causes of canine aggression. Behavioral changes, especially aggression, are often the first signs of this disease. Even a dog that was once friendly to strangers can become aggressive if it has extremely low thyroid levels. A veterinarian can do a blood test to diagnose hypothyroidism.
The medical causes of aggression in dogs can sometimes be more subtle than growls and clicks. A dog can suddenly start to get on people’s feet or lock the doors to exercise dominance. Another cause of aggression is cognitive dysfunction syndrome (CDS), sometimes referred to as “dog Alzheimer’s disease.” CDS can cause behavioral changes due to the loss of brain cells caused by brain degeneration.
