It happened this morning. He was getting off the bed and I thought he just slipped on the floor. I looked over to see if he was OK and then I realized he was having a seizure. He had one a little over 2 years ago but I didn't witness it. It was very scary. His legs were twitching and his tounge was swollen and a chaulky purple color; his pupils were dialated and he peed and pooped. We're keeping a close eye on him but I'm so worried that he might have something wrong with him. He's not even 4 years old. The last time it happened we took him to the vet but they didn't seem very concerned about it. He said if it happened again to bring him in and they would run some tests but I don't know if he meant 2 years later or not. Anyone have a similar experience with their lab?
