There are many different types of dog grooming brushes. Slicker brushes, like the Hertzko Slicker Brush, can be used for de-matting and de-shedding most coat types. You can tell a slicker brush apart from the other types of dog brushes, because they have a very distinct look. They either have a flat or slightly curved head with rows of thin wire bristles. The bristles are usually curved at the end.
