Hi I'm new here. We are in the process of testing our dog for cushings. He is approximately 12-13 years old. We noticed his excessive thirst and urination recently. He may have had it a bit longer but this has been a crazy year for us w/ our other 2 dogs being sick with cancer and unfortunately losing them. But my concern at the moment is that our dog is just wanting water NONSTOP....we are basically at the point of putting up the bowl and only giving him a little at time through out the day. I feel bad for him but i dont want him to get sick by having TOO much water and in all honesty, we can't keep going out during the day to let him out. We are just lucky that my husband is home right now to do that. Any suggestions or things we should ask the vet? I really hope we aren't facing a pituiatary tumor w/ this guy. He's been our rock through all of this and i hate to see that he's now sick.
