Q. I have a 9 year old Basenji mix that has begun to twitch while laying down and his head appears wobbly. His eyes twitch and he nervously jumps.
A. Sometimes dogs do twitch whilst they are sleeping but it could also be a seizure. Has this happened more than once? Has he had access to anything toxic? Is he normal when he wakes up. Do all four limbs move as though he is swimming or paddling?. If so that is a seizure. Sometimes dogs may just have one seizure and then never again. If it happens again then speak to your vet as they may want to do some further tests to see what is causing it. Most likely causes are brain tumours or epilepsy.
If he may have had access to anything toxic then contact your emergency vet.
