Didn't work for me, I waited 5min.
I find "strangled cat" sound to be of bad taste.
Seems like it's stressing out the dog more than anything else.
If you want to train the dog the fetch and eat strangled cats keep it up though.
Animal will learn to associate any stimulus to food after a few examples.
I refunded your steem. There is bug on code. I will work it. Thanks for your advice
