This is TMI but is there something wrong with my puppy?? Please help

Call me Cris 😜 • Life is what you make it 🙃👍🏼

He’s three months old and this morning he pooped three times without even touching his breakfast. And each time he pooped it got more watery until this came out.

Should I take him to the vet?? Has this ever happened to your pup?? Please help. I new to dogs. And I don’t want anything happen to my little buddy.
