It sounds as Duster is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material or a stomach ulcer. 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 anti vomiting injection, antibiotics and a special food for a few days in order to get better.

    Oh dear! The vomiting could be due to many conditions including eating something she shouldn’t have, bacterial over growth, a viral infection, parasites or even organ disease, poisoning or intestinal blockage. The blood could indicate a gastric ulcer, a foreign object in the stomach, stomach worms, a cancer or poisoning. It's impossible to know the cause of the vomiting without some diagnostics testing such as bloodwork and a fecal exam. Radiographs may also be needed. any time a pet vomits blood, I recommend to have them examined by the veterinarian. Potential treatments include drugs to stop vomiting, drugs to treat a potential ulcer and perhaps some sort of fluid therapy. Many times a bland diet can help and then a slow, gradual introduction to the normal food can be done. A bland diet can consist of 25% boiled white meat chicken and 75% boiled white rice. This should all be plain. A good diet in general is Royal Canin. It is low residue and highly digestible. I hope your pup starts feeling better quickly! Please feel free to post any additional questions!
