This is a heart breaking story of a lady who wrote a review of a dog shock collar at Amazon.com. You can see the original review on this page > Amazon shock collar review. Just scroll down to the review by “GiftGiver”.
If reading this does not tell you that shock collars are utterly cruel (and should be banned), then I don’t know what further evidence you need. Please read this story all the way through and DO NOT put your dog through the same situation – it is so unfortunate to see that these collars are still on sale and people still buy them.
