My six year old terrier mix has stopped eating and drinking. I can coax him to eat a little, but he isn't showing any interest. His bowel movements are normal to slightly pasty and orange. He is lethargic, but responsive, still enjoying walks and visits from concerned friends. This has been going on for 5 days. He has been to the vet. The blood and urine tests are normal except for indicating dehydration, a barium xray showed no blockage, but another xray did show some cloudiness in the lungs, although he isn't coughing or showing any breathing distress, he has no fever, he tested negative for lyme, he shows no sign of tenderness when limbs are manipulated, teeth and gums look normal. 2 days ago he had IV fluids to treat dehydration, was given mirtazapine to stimulate appetite and metronidazole as a prophylactic antibiotic. My question is, what do I do next? Any ideas for further tests? Thank you.
