Gunner sounds very ill and he needs to see a vet right away. When a dog has been vomiting for more than 24 hours, that requires a trip to a vet. He could have a foreign body, pancreatitis, or may have eaten something rotten. The vet can diagnose what is causing him to vomiting, he will need IV fluids for hydration, and can prescribe any other treatment the vet deems necessary. Please take Gunner into a vet now.

    It sounds as Bella is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking her to the vet the first chance you get, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.

    Throwing up can have many causes. It is basically a problem with the stomach and intestines caused by an intestinal blockage or partial blockage (especially in young dogs, or food over sensitivity, eating something that does not agree with the dog, intestinal parasites, bacterial infection, viral infection, the weather, food change, stress, etc.  Since your dog is not eating you cannot do a bland food trial and therefore you need to take Blue to your veterinarian for an exam. Your veterinarian will want to do blood work and possibly x-rays to rule out a blockage and check organ function. Please schedule an appointment.
