My collie/retriever mix Copper had some sort of episode tonight that I've seen one other time with him. The first time was last Spring. I think it could be a seizure but there are not convulsions. Does a seizure always include convulsions or shaking movements?
He seems to know when they are coming and both incidents were nearly identical, only this one lasted longer. He begins by trying to get close to me but has trouble walking. My other dog immediately starts sniffing him and acting funny as well. Both times I was able to get him to lay down. He pants heavily and then it suddenly stops and he clenches his jaw. His front paws begin to arch above his head and are rigid. Almost like he is about to scratch the top of his head. One rear leg is also bent into his lower body and is also rigid. He only occasionally seems to take a breath during this time but his jaws are clenched tight. His back also seems to be arched. His eyes look blank and slightly rolled into his head. This part lasted maybe 1-2 minutes at most but felt like forever. When it seems to be over, his legs relax and he starts panting again. Within a few minutes he was able to stand on his own and seemed ok for the most part but was a little disoriented and tired. To top all this off, Copper had an FCE (basically a spinal stroke) 2 years ago. He was paralyzed in his rear legs but has since recovered although he has some lingering weakness. I don't know if it is possible that the conditions could be related? He was his normal self today until the episode. He's up and walking, so I don't think it could be a stroke... or could it? We will make a call to the vet tomorrow but if anyone has seen something similar, please let me know what you think. Thanks!
Jenn and Copper
