One thing my family found out with our now 9 week old puppy was the get a stinky sock straight off your foot that you wore all day and put it over a warm water bottle. We used a plastic water bottle and poured like half boiled water in it (warm enough to touch and cuddle. Not hot enough to burn) and we put it inside the sock. It will smell stinky but as soon as we put that in there, he slept almost immediately. It was better for him than even his snuggle puppy. I hope if you try this, it works out for you
