Low thyroid, aggression and seizures

I am on my bandwagon again. I received a plea a week ago from someone with an adolescent dog with seizures and unexplained aggression. I urged them to send blood to Hemopet. Low thyroid often causes both aggression and seizures. They went to their vet who said it was “severe, idiopathic epilepsy”. He said it was probably untreatable, BUT, would not euthanize the dog because it was too young. I am hearing this right? He did not want to do a thyroid panel. I am told.

Well, IDIOPATHIC (sounds like “idiot”, right?) means “no known cause”. If you don’t test, you will not find the cause!!!!

This poor dog was then dumped at a high-kill Los Angeles shelter. He will probably be terrified for a few days,then killed.

PLEASE take control and be responsible for your animals. They are totally dependent on us to DO THE MORAL THING. Take care of them. Do not abandon them, please…

Range of behavior problems
Dr. Dodds and other veterinarians and researchers have been linking changes in behavior to hypothyroidism for more than a dozen years. The various types of abnormal behavior can be grouped into three categories: aggression, extreme shyness, or seizure-like activity.

The cases involving aggression are often similar to Hannibal’s. A previously even-tempered animal lashes out at another animal or human without any warning. One such dog under the care of Dr. Dodds was successfully participating in performance events. One day the dog’s behavior changed radically and he “would go berserk” every time he saw people he didn’t know. Soon he was banned from the training facility because his aggressive behavior had escalated to dangerous levels. Sadly, it’s not unusual for dogs with untreated hypothyroidism to become so aggressive that their owners are no longer able to manage them.

On the other end of the behavioral spectrum are the dogs that become very shy and fearful due to hypothyroidism. While not a threat to humans, extreme manifestations of this kind of behavior still render the dog difficult, if not impossible to keep as a family pet. In addition, these animals are unlikely to be able to continue any activities such as obedience, showing, or working.

The final type of behavioral aberrations seen with hypothyroidism is sudden onset of seizure activity. According to Dr. Dodds, these dogs “appear perfectly healthy outwardly, have normal hair coats and energy, but suddenly have a seizure for no apparent reason.” The seizures may be infrequent, and may include aggressive behavior immediately before or after the seizures.
