Recent studies have demonstrated that typical dry dog foods have significantly less efficacy in reducing accumulation of dental substrates compared to a specifically formulated and processed dental food. This study compared the effects of a typical dry food and a dental food on plaque accumulation and gingival inflammation in dogs during a 6-month period. Daily feeding of the dental food significantly reduced plaque and gingivitis by 39% and 36%, respectively, compared with daily feeding of the typical dry food. Feeding a food that decreases plaque accumulation and reduces gingivitis contributes to canine oral health maintenance.
