You asked about clippers and clipping in one of your posts (prob on the main forum not here, sorry)...
Susan Harris - Grooming to Win is a great book going into detail on grooming. It does cover different prep styles for different breeds for showing along with all the basics. Good reading.
Clipping - general clipping for bp, jaws, ears and "feathers" - there are many clippers out there. More now than ever - heavy duty meant for body clipping and light weight, palm sized small battery operated ones (don't work so well on pony/mini hair). I favor the Oster A5 and also the Laube's. My Laube's (2 sets now) are so old they don't have the same names anymore. I received the one pair from an acquaintance - said if I could get them fixed, I could have them. I sent them to a Laube repair shop and paid a fraction of a new pair to get a new motor (wiring different in GE than in USA - they were basically fried) and service... I still have them after 15 years (they were 10 years old when she gave them to me). I have to send them back in again - over due for servicing & replacement of moving parts that I suck at doing.
ANd - that's what "Cupid's" do, isn't it?
