@huguenot Be aware that anything that has your scent or human scent on it is of high value to the pup.
So, to assist with your sanity and to help the dog get over this phase - remove any items that have your scent on them or contain the area the dog has free unsupervised access.
The more the dog does this behaviour, the more it becomes embedded in the dog that this behaviour is okay and the more likely it will continue to happen into adulthood. It is not cute for an adult dog to be dragging stuff out to the backyard and it's not easy on the pocket when the pup starts to graduate to things that are on tables such as phones, remotes and precious, not easy to replace items.
Give the dog chewy stuffed toys that you play with the dog with, Kongs stuffed with good recipes (do the research - there are plenty) and freeze them so it has an alternative to your house-hold items. But, until it gets through this phase, remove the items or contain the dog.
