Whether it’s their own toys or your favourite pair of shoes, there’s a perfectly good reason for this behaviour.
According to the American Kennel Club, hoarding is something that has been hard-wired into pooches.
"Hoarding behaviour in dogs is an instinctive behaviour that originated during the time when their ancestors did not have regular meals appear magically, at least twice a day," the publication says. "They were lucky if they ate every few days, and if there was a jackpot of more food than could be eaten at once, these dog ancestors would sometimes take some food and bury it in a safe place for later. Wild animals do the same thing today."
Thousands of years later, this instinctual behaviour is still alive and well.
However, that’s not the only reason.
There are a number of other reasons why dogs chew your belongings. Your puppy could just be looking for something to play with. According to Vet Street, dogs don’t understand the concept of stealing. They will simply see something they want and go for it.
On the other hand, if your dog is picking up something of yours while you are looking at them. The expectation could be that you will chase and play with them.
“These dogs know what is important to you and they will grab the item just at the right time, so you see them do it, says the publication. “Their great hope is that you will follow in hot pursuit.”
