Getting puppy used to being alone

Leave the room for a few seconds and then come back in. Make sure that you make no fuss as you leave or return – it is just a boring occurrence that they don’t need to get worked up about. Build up to leaving them for longer periods. Also try going out of the house as above. Only ever return when they are quiet (even if they are quiet for only a moment). Make sure that you practise this frequently (purposefully leaving even if you have no actual reason to).
