* Curiosity. Dogs are naturally curious creatures, and they may be drawn to the smell or texture of underwear. They may also be interested in the fact that their owner is wearing them.
* Attention-seeking. Some dogs steal underwear as a way to get their owner's attention. They may know that their owner will react strongly if they see them with underwear in their mouth, and they may enjoy the attention they get from this reaction.
* Anxiety or stress. Some dogs may steal underwear as a way to relieve anxiety or stress. Chewing on something soft and familiar, like underwear, can be a calming activity for dogs.
* Medical problems. In some cases, dogs may steal underwear due to a medical problem, such as pica (the compulsive eating of non-food items). If your dog is suddenly starting to steal underwear, it's important to take them to the vet to rule out any underlying health conditions.
If your dog is stealing underwear, there are a few things you can do to stop them.
* Remove the temptation. Keep your underwear in a place where your dog can't reach them, such as a drawer or a closet.
* Redirect your dog's attention. If you catch your dog stealing underwear, try to redirect their attention to something else, such as a toy or a treat.
* Train your dog. You can also train your dog to stop stealing underwear by using positive reinforcement. When your dog behaves well, reward them with a treat or praise.
* Seek professional help. If you're having trouble stopping your dog from stealing underwear, you may want to seek professional help from a veterinarian or a dog trainer.
