Many times these types of cysts will resolve on their own. You can use a medicated shampoo like Dechra DermaBenSs Shampoo that will help flush the follicle. However, if it gets big enough, it can sometimes get infected and need treatment from a vet. Try to avoid squeezing these cysts as you can cause some more damage. Here is a helpful article on sebaceous cysts, which I think is what you may be seeing: http://healthypets.mercola.com/sites/healthypets/archive/2011/08/16/sebaceous-cysts.aspx
