My cousin recently bought a training collar for his dog. Yesterday, he came to my house to ask how to use a training collar on his dog. He also brought his dog named Lucky. At first, Lucky was agitated when my cousin put on the training collar. In about 10 minutes, I have taught him how to use the product on Lucky. I repeatedly emphasized to my cousin that training collars for dogs are only used for training, not to be left on his dog’s neck all the time as they can pose a threat if left on his dog unsupervised by him.
