Hi! Have you put some old clothes with your smell with the puppy? Or better, with his mum's smell? I had Spettro sleeping alone in his crate since first night (he was a very good boy anyway, sleeping alone from the beginning without almost complaining), and I had brought to my breeder a bunch of old clothes that she put with the puppies and the mummy, and she gave them back to me for making him stay with his family's smell
