Okay my 2 yr old mutt puppy had what we believe was a seziure today. He was twitching then started running crazily. Scariest part was the stairs he ranish up then fell down em. I carried him outside at that point. Didnt last more then a few minutes but noo clue as to why. Hes never had a prob before. Could this be heat maybe? The temps just jump right now here by over 10 degrees (western pa) if it happens again im off to the vet to do whatever we can do within our means. Hes been okay sense but still very scary i love my puppy cap't jack.
