Give it a bath. If the puppy is younger than 5 months; use a sponge and some soap. Try not to get the soap in the puppies eyes or ears. If it is the puppies breath use a finger tooth brush( you can get at, Petsmart, Petco, and some vets offices). Put a little tooth paste on the brush. Get the dog to smell and potentially like the tooth paste. DON'T USE HUMAN TOOTH PASTE!
if it's scratches take tooth paste not gel use something like arm an hammer tooth paste and rub it on it let it sit then take a slightly wet rag and rub it

The mantle is not a thick paste; it is a layer of the Earth below the crust and above the core. Its consistency is similar to a solid due to high pressure and temperature, but it can flow slowly over longer periods of time, which contributes to plate tectonics and volcanic activity.
the core
The "Crust" is one of the Earth's layer.It can be compared to an eggshell
