Most dogs self regulate their water intake. However, when there is truly polydipsia (frequent drinking) and polyuria (frequent, dilute urination) - there is a reason for it. Even if it's just excessively hot/warm in your area right now...that would still be a reason why some dogs drink more, cyclically.
Dogs who eat kibble will drink more than dogs who eat raw or canned. That said, that doesn't mean that kibble-eaters' urine is expected to be more dilute. It just means they need more water in proportion to fulfill digestive needs.
Given your kiddo's age, it's hard to imagine their is something like D.inspidus or whatever...but if you truly do see PD/PU....it's something to keep pushing in terms of getting a diagnosis. I too was told Wylie's former PD/PU was "nothing"....well, after finally finding new vets....turned out Wylie has Atypical Cushings and hypothyroid.

This.
Kibble fed dogs will drink more, but this does sound abnormal.
Diabetes, diabetes insipidus, thyroid problems, liver problems, kidney problems, and cushings all need to be considered. Average for kibble fed dogs is about an ounce per pound daily (give or take). If he is drinking a ton more than that, diagnostics are needed. Could start with blood and urine testing. If the vet hasn't offered to do these things, then it's time for a second opinion. Unfortunately, some of the things listed above are quite common in Yorkies, so it's important to get to the bottom of it.
