I got my German Shepherd/Border Collie mix in 2003 from a stockyard in Brewton Alabama. Two years went by and he became the most loving sweet, laid back, playful dog in the world. Then on a cold night in December he fell to the floor stiff and moving his legs as if he were swimming. Although i wasnt there that night, my dad set the scene for me. When he first started he was given Primidone only once a night. Then not much longer after that he suffered a bad seziure, this was the longest ever nearly 5 minutes. The previous ones he had lasted only around 2 to 3 minutes. So "Doc" our local vet sudgessted that we give him the pill once a day and once a night. he usually has one every month, but there have been cases where he has gone nearly 2 months wuthout one.  After a seziure he seems kind of tired, but soon after is out running and playing with our cat. Lucky now is about to turn 6 on Christmas and he continues to be his old self despite the cruel seziures and live each day to the fullest.
