Just wanted to let you know that there is a lot of misinformation on that site too. So unless you can find data to back things up elsewhere...take it with a grain of salt.
Adina - you are correct in that not all of the information here is accurate. There is an article that addresses seizures in dogs. They discuss seizures caused by head trauma (our Mariner). The article states that anti-seizure medication is not effective for dogs with this. This is contrary to what I have read everywhere else and to our personal experiences with Mariner.
