I have a 16 year old sheltie, Joshie, who was diagnosed with chronic renal failure on Aug. 28th. Was drinking lots of water and urinating a lot. We took him to the vet for intravenous fluids for two day and now I have to force water using a syringe,or give them subcutaneously. Why won't he drink any more. Is there any way I could entice him to drink on his own again.
