Dogs may exhibit anxious or restless behaviors due to separation anxiety, such as biting the quilt. This is a way for them to seek comfort when they feel lonely or unsafe. Dogs may also chew on objects, including quilts, to relieve discomfort due to gum discomfort or pain.

Dogs naturally like to bite things, especially when they are young, they will use their mouths to explore the things around them. The quilt is soft and seems like a new object to dogs, so they will chew on it to explore its texture and taste.
