Here are some possible reasons, but it's best to consult a veterinarian or a dog behaviorist for an accurate assessment:
Possible reasons:
* Nest building: Many dogs, especially those with a strong prey drive, engage in nest building behavior. They might be trying to create a safe, comfortable space for themselves, similar to how wild animals prepare their nests.
* Play: If your dog is playful, she might be using the blanket as a toy, especially if she's young or has a lot of energy.
* Anxiety or insecurity: Pushing and holding blankets can be a way for dogs to self-soothe and feel secure.
* Boredom or lack of stimulation: If your dog is bored or lacks mental stimulation, she might engage in this behavior as a way to occupy herself.
* Physical discomfort: Sometimes, dogs might engage in unusual behaviors due to physical discomfort, such as pain or itchiness.
To get a better understanding of your dog's behavior, consider:
* The context: When does this behavior happen? Is it when you're leaving the house, when she's tired, or at specific times of day?
* Other behaviors: Does she show any other signs of anxiety, stress, or discomfort?
* The dog's age: Younger puppies may engage in this behavior as part of their exploration and development.
If you're concerned about your dog's behavior, it's best to consult with a veterinarian or a certified dog behaviorist. They can help you understand the underlying cause and recommend appropriate solutions.
