How Often Do You Bathe Your Dog?

I don't bathe mine at all. I used to send them to the groomers once ayear but earlier this year Carling came home with his coat looking worse then usual. They are Alaskan Malamutes so they 'self clean' anyway and dont tend to stink. Every now and a again I will spray their coats with stink bomb spray to keep it nice and soft. I also grrom them myself as they tend to blow their coats.
I have been told not to bath Alaskan Malamutes as too much can damage their water proof coat.
