It sounds as your pet is suffering from a gastrointestinal condition, possibly an infection. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an antibiotics and a special food for a few days in order to get better.
