Louie has been coming on nicely on his whislte training - I have made mistakes and he has ignored the whistle a few times, other than that I am confident it will work out eventually. However I accidently covered half of it with my finger when I went to recall him and it made a deeper pitch - and he came straight away. I have the ACME 2011 1/2. Has anyone else had this accident with their whistle and has your dog behaved/responded differently?
