My dog won’t eat and has become very thin

A dog not eating, vomiting, or having diarrhea can be caused by many reasons, including indigestion, gastritis, intestinal parasite infection, and viral disease. The owner can withhold food for a period, then feed pet broad-spectrum anti-inflammatory medication, anti-emetic drugs, and probiotics, and observe whether symptoms improve.

If the dog’s symptoms do not improve or keep recurring, take it to a veterinary hospital promptly for diagnosis and treatment to avoid delaying care.
