I have had my brindle boxer Woody for 9 years now and yesterday morning i woke up to him having a major seizure.it lasted around 10 mins and eventually he snapped out of it. in the course of the next 6 hours he had 3 mini ones, where he started faoming at the mouth and shaking his head, and 2 more big ones on the floor. it took him a while to snap our of them and as soon as we could we took him to the ER vets. he has been there since last night and today he only had one big and 1 sml fit. his blood and urine samples are all ok.. nothing unusual and so we are getting a cat scan done on thurs. i am very scared as the blood tests were normal it can only mean it is something very serious. I was wondering if anyone has experienced anything like this. It is so unusual as he has never showed signs of anything along these lines. scared that its a brain tumor and will have to be put down.. can someone who relates please give me their advice.. would appreciate it loads.. thanks
