I started grooming my Yorkiepoo because every groomer I called wanted over $40 for a 4-pound dog. I bought the Oster 16pc Deluxe Dog Clipper Kit w/DVD, Medium Duty, and the Andis Dryer w/stand; both from PetSmart.
The clippers get a bit hot but I use Cool Lube, and hopefully I will get faster with practice. The clippers are really quiet and the dryer is too. I take him to the vet to have his nails cut ($10).
You can do it! I'm cheering for you.
