I should have mentioned that the "weapon of doggy discipline" is a 2 litre pump action garden sprayer used only to squirt water.

Frosty does tend to go for the nozzle of that too - loves the game but it stops her from doing what ever it was that I didn't want her to do like sniffing the washing with a view to testing the tug potential...

The whole barrel of it acts as a hand guard but she is pretty accurate when it comes to chomping on nozzles - not that I encourage that kind of thing.
