I´m new in this forum and say at first "Hello everybody".
My name is Cornelia and i am German. My husband Stuart and I have 2 Bulldogs: Frieda (Goomba Happy Miss Frieda). She was born in Pennsylvania 6 years ago. I picked her up when she was 9 weeks old and flew with her - in the cabin - to Frankfurt/Germany. She is a Bulldog really 'fit for function' and we are very very happy with her. Kosmo, our second bulldog, is her son. He is a little bit rough in his movements, but adorable friendly and wants always to kiss people he likes.
Now I will talk (finally :-) about this head tremor. It is a harmless neurological disturbance. Vets don't know so far what exactly causes this. By the way, it is not restricted to Bulldogs. Especially boxer and Dobermann have this from time to time too.
You can stop it simply with a daily pill of Vitamin B Complex for about 3 weeks. Take the same pills like for humans. Repeat the cure after half a year. Because Vitamin B is only fat-soluble, give the pills in a piece of butter.
You will see, Vitamin B will stop this head tremor very soon.
