Could a Raw Dog Food Diet Replace the Need to Brush?
Many raw diet proponents claim that the nutrients and/or chemical composition of a raw diet keeps dogs from developing gingivitis or periodontitis. We’re not aware of any studies that have proven these claims, but the persistence of the anecdotal evidence of this phenomenon (to say nothing of its evolutionary success) suggest that there are dental benefits to a diet that includes raw, meaty bones.
Interestingly, it’s not just the physical action of the chewing; many owners, who fear the potential for bone fragments to impact or perforate their dog’s intestines, use commercial food grinders to grind raw meaty bones into a fine paste before feeding them to their dogs. Many of them report the same dental advantages as those who feed whole raw meaty bones to their dogs.
Again, there are likely to be outliers – dogs whose teeth and gums develop disease even when fed a supremely healthy raw diet.
However, it’s been our experience that people are either open to the idea of feeding a raw diet (whether commercial or home-prepared) or not; the condition of their dog’s teeth may be a contributing motivation, but not the sole factor guiding the decision.
