Miss Lizzie, likes to paw the rug to create a nest at bedtime. Obvioulsy, I redirect her so she doesn't ruin the carpeting. She will lay down and paw the air before she settles down. I have given her a sheet to lay on so she can rake the sheet or blanket to create a nest but she never uses it. She only does it on the rug. It's pretty funny to see her raking the air in front of her because she isn't allowed to rake the rug. Do any of your puppies do this? Our last female did this but not to this degree.
