I have just leant my remote spray collar (NOT E Collar) to a friend who was having trouble with her weim not leaving their chickens alone - I thought it would work but it didn't so she is sending it back to me - I brought this maybe four years ago and it did not work at all on that partuclur dog at the time - I did try him with it recently though and it had a great effect on him.

what is your opinion on these?
