Hmm, I have a large yard, and we cannot afford to fence it, so have used the underground fencing where the dogs wear the collars. If they get too close to the edge it gives a beep warning and if they keep going it will give just a small correction, like touching something staticky. I checked it on myself to make sure it wasn't painful. It is just startling/uncomfortable. This way they can freely run the yard and I don't have to worry about keeping them tied or one of them chasing a rabbit out into the street.

Also the neighbor throws out old pork and chicken bones in his yard... had problems with the dogs going over and grabbing the bones and then of course not coming near me so I had to chase them down to get the bones.

They only wear them when they are out to romp in the yard for awhile and they don't even try really to go out of the yard anymore. Maybe some still think this is cruelty, though I hope not. It actually has been a wonderful solution and I don't have to be fearful or be scolding them, just let them run and play freely.

The duck tape is definite cruelty to animals, the dog cannot drink or pant this way, and I would report it immediately. Take pictures if you see him that way? I would think that would be illegal...
