as everybody else has said, no head and shoulders should not be used on your dog.
Golden Lab? You mean Yellow Lab I think
Although Most people who say golden lab are in fact talking about a yellow lab, or a Golden retriever, there is in fact a line of "golden lab” They are similar too the yellow lab but a much deeper golden color then the usual Blond in a yellow lab. I myself own a "golden lab".
If_i_were_u, I am interested too know if your dog is truly a golden lab, or in fact a more common yellow lab, or golden retriever, simply because I very rarely hear of people with actual golden labs.
