Most pets who suffer from seizures are treated wit drugs such as phenobarbital and potassium bromide. While these drugs may be effective in controlling seizures, they can also be quite harmful to the liver and other organs. In some cases, dogs have been found to be drug-resistant, meaning these drugs do not have any effect on them. CBD can be a safe alternative to these drugs and has been shown to work well in drug-resistant cases of epilepsy.
