Just wondered if anyone has experienced anything like this or similar and could offer an explanation or any advice as to the cause. My 11 year old yorkie has been checked by a vet but they cannot find anything wrong or an explanation, he's had heart tests/blood tests, you name it he's had it. He's been "fainting" about once or twice a year from 2003. They happen at about the same time, during the night and he goes very stiff and dead like, very ridged out streatched front legs, wide staring eyes, very out of it, it takes him about 10 minutes to fully recover and then he's fine. All the tests have come back normal. The vets only comment was that he could be going into a deep sleep and then waking up fast but his heart can't catch up with the speed of waking and thus making him faint. He is fine in every other way, eating and going to the toilet normally, playing and seems ok in himself, I'm just concerned when this happens as it's pretty frightening and wanted to know if this is something any yorkie owners have come across before. He's has fainted twice in 2003, once in 04,once in 05 and twice this year already. It all happens between 9.30pm- 4.30am. Thanks for any advice. Lisa
