Clipping Dew Claws - Always a Drama?

The highlight of the doggy maintenance calendar came around again last week. Yep, those dew claws were starting to look like contenders in the guiness book of records. Unfortunately Jack is about as receptive to nail clipping as I am to molar extraction, so stealth was required!

We've tried wrapping him in a towel, bribery, kindness and being firm - all resulting in total failure with us coated in hair and a small pug sulking in his bed.
The only technique that works for us is sneaking up on him while he's asleep and snipping a nail with toenail clippers (he can sense the guillotine dog nail clippers
from 2 feet!)

Any tips on how you clip your dogs nails - we'd love to hear from you?
