I would hesitate to use something like WD40 on my rug, both for the sake of the fibers and especially for the puppy who will surely be exposed to that both through his nose and his mouth. Try something that will not be potentially toxic to your dog.
As for getting it off your dog's paws, I'd be contacting a vet to make sure whatever you use is safe for your pup. Things we can tolerate, they sometimes can't. Better to be safe and ask a vet.
I've had great success with peanut butter (in hair), don't know how it would work on carpet fibers though. I'd do a Google search. You're sure to find your answer that way. Good luck!
