He's so excited, I wonder why Pugs, especially, shake so much when they are excited.
There was a sweet spot in every dog we had that if you scratched it, the leg couldn't help shaking.

He came in, covered in something. It smelt like white spirit.
Rather naturally thinking "OMG!", I rushed him to the bathroom.
Knowing how much cats love water, I kept talking to him, in soothing tones, as you would...
I bathed him and even dried him with a hair-dryer! He didn't even flinch!
