My dog is losing weight, vomiting, and has diarrhea. Is it bloat?

Hello there, My 18 month old shepherd mix (50 lbs) seems to be losing weight and vomiting every few days. He also always has loose stools (I've tried switching food several times). I'm concerned this could be bloat, but not a large dog (however, he is shaped like a german shepherd). Any advice?

Weight loss, vomiting and diarrhea could be caused by a number of things, including parasites, diet changes, toxin ingestion, infectious viral diseases, blockage in the intestines caused by ingestion of a foreign body, food sensitivity/allergy, decreased pancreatic function, or a mass/growth in the gastrointestinal tract. Please make an appointment to have Buddy seen by a veterinarian as soon as possible to allow for diagnosis and treatment. Bloat can occur in any dog, although large deep chested dogs tend to be affected by it more frequently. A distended abdomen, retching without production of vomit, salivation, pale gums, and labored breathing can be signs of bloat, and if you notice these signs you should rush Buddy to the vet immediately.
