puppy has just been sick

[desperateforaholiday]

I don't know whether to take him the vets tomorrow, he's 10.5 weeks old lab cross Newfoundland. He was fine after his tea, had a snooze then had diarrhea, it looked a bit mucusy and now He's just been sick, so worried as he's not due his next vaccination until wednesday. He's only been out in the garden on a lead to do his business.

If it wasn't the weekend id see how he goes but id prob get him looked at.

The mucus suggests in may be colitis. But puppies can be sick and it be nothing to worry about, so I'd feed him chicken and rice and monitor closely and if it gets any worse, go to the vet.
