2. 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.
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.
