I am severley concerned about this-I don't think this is a normal epilepsy. I'm thinking this may be a neurological disorder. There have been increasing cases of brain disorders as well. What did the vet say? How long are you able to keep him while I get in touch with Sue?
The zoning out is a seizure. It is a neurological interruption of the brain neurotransmitters. Sound like a lot of dead spots. If you're wondering how I know, not only do I have experience with dogs, but I also worked with Brain injuries in humans. A lot of this happens when the brain is dying. I don't mean to scare you at all, but this may be something else. Not all vets are up to date on neurological disorders. I'll try to talk with Sue tonight to see what she can do if you want me to call her.
