What would cause mucus and blood in a dogs stool.... more info? - blood in stool more condition_symptoms

I have a male Chihuahua that is 2 days old and was very bad blood and mucus in the stool and is quite smooth and it feels terrible, even by his life and does not really himself. She also had worms and was given one tablet 6 and the next day I realized OR2 in Womser Stoo and their droppings were both normally something d eso?
