Can you also provide a tutorial on ear trimming? I snip away with scissors and can often get it almost ok, but a little shaggy lately.
Also, if there is a general purpose electric trimmer that you suggest for hocks, ears and anywhere else (e.g. bums), I would love to know the make and model you use.
Cheers!
Barb,
I just happened to put an ear tutorial up last night as well

As for a razor, I found that a lady's personal razor works just great for my purposes! It's a Remington model BKT-1000. I think it cost me about $20 at London Drugs a couple of years ago. Comes with a blade guard that is really handy for trimming hock hair, and is removable for easy use on the bottoms of paw pads. Runs on two AA batteries.
I don't use the razor on the ears, for that I use thinning shears (also purchased at London Drugs for about $15). I only use the razor on the bottoms of the paws and the hocks.
