I am sorry to hear about Tiddles. It sounds like he needs veterinary care if he is lethargic and cannot keep water down. We worry in dogs with his symptoms about infections, pancreatitis, foreign body ingestion, and more. The vet will examine him and may recommend testing such as fecal testing, bloodwork or x-ray depending on his symptoms. He may need IV fluids to help rehydrate him and special injectable medications initially since he is vomiting.
