I am so sorry to hear your Westie is having this issue. It sounds like a few of the primary causes of increased water intake were ruled out. There are other possibilities to consider:

- Diabetes insipidus which is completely different than the regular diabetes mellitus. There is no increase in glucose levels and it is related to an impaired production of a hormone called ADH (anti-diuretic hormone) from the brain (central DI), or an impaired ability of the kidney to respond properly to the ADH (nephrogenic DI). CLICK HERE for more information on this condition. Often the only way to diagnose this is either an MRI which is not always conclusive or response to treatment with desmopressin which is a medication that is applied as an eye drop and if used with DI the increased water intake will taper but if not then the diagnosis of exclusion is
- Psychogenic Polydypsia which is essentially that there is no physiologic cause of increased water intake that we can understand but a dog feels the need to drink copiously because of thirst. There is no treatment but to allow access to fresh water and outdoors. CLICK HERE for more information on this condition

Since diabetes mellitus and cushing's has been ruled out these would be my top differentials for your beloved Westie. I hope this makes sense but please let me know how else I can assist you both today
