Shih Tzu Epilepsy. The brain’s neurons shoot off too many “move” signals, which lead to seizing muscles. However, the most common cause is canine epilepsy, which is caused by abnormal electrical activity in the brain.
My wife thinks the dog is depressed, but that is just how shih tzu are. If he does then he may need treatment. Epilepsy is believed to be inherited in between 25 and 30 of breeds of dog, for example, labrador and golden retrievers, beagles, dachshunds, belgian tervurens, keeshonds, cocker spaniels and german shepherds.
