I am trying to help someone train a Shih Tzu puppy long distance that has almost no drive at all. She isn’t food or toy motivated, but I saw a video of her following the owner, with a lot of praise. I was told that extreme praise is not a good idea, and that praise as a reward should be calm and positive but not squealy and over the top because the dog will eventually stop responding. I suggested they only train with food when the puppy is hungry. I also said to try a flirt pole, but wasn’t able to explain how to use it in a way they understood.. I’m not close enough for hands on training. How can a dog not be motivated by anything? They want to train her but don’t know how or where and I have no experience with tiny dogs. Can anyone help?
