Yes, you shouldn't brush a dry coat, it breaks the ends.
What sprays does everyone use?
Can you recommend a few as they aren't always available over here?
Does anyone make up their own mixture to spray? Some of the old Yorkie books I have, from the very early days when the breed was being developed over here, mention these, but there are some really weird recipes in them......
hydrous wool fat, benzoate lard, grains of phenol,alcohol......or oils mixed with kerosene & a little paraffin......
