I have a boxer around 1.5 years old. His name is Reno and he is a fantastic dog. He used to go to work with my wife until one day he started having head tremors. At first we were thinking that he was having seizures but it is only his head. He is fully responsive, will lick me, go get his toys, act normal but his head shakes from side to side. It is one of the strangest things I have seen in a dog. They have calmed down and he hasn't had any episodes until this past week. He is now having them at least once a day, lasting from 15 seconds to minutes long. I am stumped, does anyone have any information or suggestions to help the situation..?
