This might help this might not. I have a little guy you can find his story here many times on this forum. He is Babybear he suffered from a few of the same symtoms as your baby. He would have these weird seuzire things but not all the time. Any ways ask your Neuro to check on AAI(Atlantoaxial Instability) this is done with a x-ray. This goes undiagnosed or misdiagnosed. You can find more info on this defect on Petplace.com that is where I found it thanks to a good YTer. This is what happened to my little guy and he ended up braking his neck. I am also involved with another group that helps parents with congenital defects and it sounds like this might be a congenital defect. If you would like some more help or need someone to talk to you can go to
Yahoo. And put in
Congenitaldogs@yahoo.com and that is where we are at. We try to research the problems and help the parents cope with everything because we all on group have gone through so much also. And you don't have to wait for a response you get one really quick and a lot more to go with it. And it is not just for AAI babies it is MVD,Livershunts,Hydrocephalus,Cancer,etc. If you have any questions about AAI please don't hesitate to ask I will help out as much as possible.
