It is with enormous pain that I am adding to this thread. Kai is experiencing some major problems which all appear neurological. I can't afford a MRI but we are doing a ultra sound on this coming Monday to see if it shows anything. He walks like he is walking on nails, very stiff and will trip, all 4 legs. When he eats he has trouble to swallow and will regurgitate undigested food. We hoped this was a inner ear infection but antibiotics n paid meds are not really helping much. Our vet feels it is a tumor on his brain stem. Not sure how to handle any of this at that's time, will just hug on him till Monday and see if the ultra sound shows any other reason this can be happening.
