Key Unity KA22 Titanium Whistle
I walk my unruly Irish Red and White Setter in the woods near my home and have trained him to return to the whistle, but this only works if he hears it! So I use this beautiful smooth item daily and it really is comforting and so much more effective than my ACME dog whistle. It is also great that there is nothing to actually go wrong with this as I have other whistles which have aplastic insert and does not always work. This is frankly not the loudest sound though it says 120db so if you are really in the middle nowhere you may need something stronger, but this is a nice item with a good tone.
