5 month old yorkie has been wet all day…

Hey everyone, just wondering if somebody knows what’s going on with my yorkie pup.

At least 3 times today I’ve picked him up and his undercarriage has been super wet and his tail is very wet.

I just went to pick him up off the couch and a part of the blanket is very wet. It’s clear, doesn’t smell like urine, and he himself doesn’t smell like pee at all.

This is very unusual, haven’t seen it before. He has been his happy playful little self all day but I’m worrying a bit because you look online and a catalogue of awful things come up.

Any ideas?
