Why dogs dig their bed or floor
A dog’s wild ancestors scratched at piles of leaves, dirt and pine needles to create a comfortable mound of bedding to rest.
Many domesticated dogs still retain this behavior; By scratching or digging the floor or their bed, your pup may actually be trying to create a snug nest to sleep.
Bed-scratching is also a territorial behavior.
Dogs have glands in their paws that leave a distinctive scent on bedding or other objects they scratch.
You may only see a tattered blanket but your dog may see and smell a space that they have made their own.
Dogs are more likely to return to a bedding spot if they already feel it's theirs.
This is why bed-scratching behaviors often begin to intensify when a new pet moves into the house, or buy a new bed for your dog.
Interestingly enough, bed-scratching is also part of canine maternal instinct.
If your female dog is getting ready to have her puppies, her bed-scratching behavior will suddenly increase. She’s making a nest for the arrival of her new pups to keep them warm and safe.
