Q. My puppy was born on oct 28th. For about two weeks now he's had diarrhea and there's blood in it. He acts fine playing and stuff. Bit has lost weight

A. it could be a gastrointestinal infection from something he ate, or a foreign body irritating the intestines. It could also be a food allergy. Chronic diarrhea usually leads to loss of weight and dehydration, if it's been already 2 weeks without improvement I would advice you to go to the vet to get it treated. He might need antibiotics and something to stop the diarrhea.
