milo hey what can i say its a gutting situation but your 100% right they know the difference fare enough a pup out for the first time correct it but like you when i,m out i want to know if my dog goes out of sight i dont need to be worrying weather she is butchering a sheep ,the other thing is electric collars are no good unless you can see the dog you cant zap a dog everytime it goes out of sight which means your dogs on this invisable lead where it cant venture out of sight
