I took my CAG in to the vet yesterday because he's been a bit lethargic and I didn't know what was up. (I opted NOT to go with the DNA test...I've come to terms with that.) Anyway, when they took blood, my sweet boy went into a stress seizure. Vet said it was a form of epilepsy. I didn't know what was happening...his right foot was cramped and didn't work, he couldn't control his feather and they were all splayed, his eyes were blinking and he was hyperventilating. It was terrible. The vet was calmed and talked to me about it as it was happening and after 5 or 6 minutes (felt like eternity) my Butkus finally came out of it and is doing great. Full blood tests were all great.
