Never come across that method.
The way we tell people at puppy classes is to just hold the thing they have still (so it's no longer interesting), cupping underneath their muzzle. They will generally let go after a few seconds. If they don't, just hooking one finger into the collar (while maintaining the rest of the position) generally makes the more reluctant pups let go.
Doesn't work on an adult dog who has learned to resist things being removed from them (but I wouldn't dare try jessandme's method on my adult dog!!!
), but is something to try before you attempt to force something away from them.
I would use the above method first - then try swapping for treats - I'd only force the issue if it was a life and death situation... but it's certainly worth knowing how to do it if the situation does arise!
