Hi all,
Lola responds really well to my husbands whistle (fingers in mouth :D). Unfortunately, I can't whistle, probably due to capped teeth :D :D Anyway, I bought a super dooper dog whistle. It looks like a silver tube and the end thingy screws in and out - very technical :o.
Problem - I lost the instructions :o. Can anyone help???
Option A If the end is screwed in (to make whistle shorter) when blown I can hear nothing.
Option B If the end is screwd out (to make whistle longer) when blown I can hear it.
What is the difference for the dogs? Which one is used for long distances??

Also I'd love to hear from anyone who has had success using one ;)
Annie
