Youch! i hadnt seen the links for the pic's and yes that is horrendous
Whoever used that on the dog should have it fitted to them and the button pressed with the setting on full. I can see now after seeing the images why you are all getting het up about the use of an e -collar , i didnt realise they could cause so much harm in the wrong hands. Whoever had hold of the collar of the dogs in the pic used it it an extreme manner which is not what the collar is to be used for.
Some people should'nt be allowed to own or handle animals...appauling!
