Spycar,
The evidence is there you just can’t see it. Periodontal disease can exist in the presence of clean crowns. You and your veterinarian are seeing clean crowns. Does you vet measure in mm the depth of sulcus at multiple locations around each tooth? Are full mouth dental radiographs taken? Until the mouth is fully evaluated you don’t know if that dog has periodontal disease.
A PMR diet is modeled after the presumed “natural” diet. We have evidence that dogs and cats eating a natural diet have significant levels of periodontal disease. At this time, based on the evidence, the reasonable conclusion is that PMR fed dogs will have periodontal disease at significant levels. This is the only conclusion that can be made. This is the conclusion of Chandler and other scientists.
I’d recommend that you contribute to the literature. Reach out to the thousands of well networked PMR feeders. Have each one chip in a few bucks and contact a boarded veterinary dentist to design and carry out a study on dental evaluations of PMR fed dogs and cats.
Until that is done the reasonable conclusion is that the PMR dogs and cats will not fair any better in regards to frequency and severity of periodontal disease then the dog and cats eating a natural diet that PMR is modeled after.
Until such study is done we have to use the data we have
