hi, Is there a shampoo you can buy to get rid of dogs dandruff?

Unlikely.  Bathing is more likely to make the problem worse unless it is "walking dandruff" a sort of mite.

Try feeding more raw animal fats - ie chicken or fish body oil to try to help the possible cause of the problem.

If your dog is starting to moult then the dandruff should cease when s/he has finished.

Ok thanks!  :)

If you do shampoo, make sure you rinse properly.  That can often be the cause.  Also add some form of oil to the diet, I use evening primrose, or you can give a tin of sardines in olive oil once a week.
