I break it down in two parts, Jack. Lets say the dog is getting 1.5lbs feed and a cup and a half water all at once at feed time and then weigh. In two to three hrs I will let him/her out to urinate and put em bck in the crate for the night. In the morning, when we empty out, we might lose 10-18oz of piss n shit. After the workout I will offer another cup and a half of water. Depending on what stage of keep we're in he/she may or may not drink it all. So what do you do when he/she begins to stop drinking the water towards the end of the keep if you dont give it all with the feed? Do you think that when they start to not want the water this could be a cause for some dogs kidneys failing afterwards?
