Observations on food tolerance in dogs have shown that differences occur between breeds--especially in the giant breeds which can have an increased frequency of soft stools. This may be explained, at least in part, by differences in the dogs' ability to utilise a diet. To investigate this phenomenon, four digestive trials were conducted using two canned and two dried commercial diets. The ability to digest most nutrients was lower in the great danes in three out of the four trials. The great danes also had a significantly higher faecal loss of water, sodium and potassium. The underlying causes should be associated with the relationship between body-weight and the gastrointestinal tract or with differences in transit time of the ingesta, particularly through the large intestine.
对犬类食物耐受性的观察表明，不同品种之间存在差异——尤其是大型犬种，它们软便的频率可能会增加。这至少部分可以通过犬类利用饮食的能力差异来解释。为了研究这一现象，使用两种罐装和两种干制商业日粮进行了四项消化试验。在四项试验中的三项中，大丹犬对大多数营养物质的消化能力较低。大丹犬的粪便中水分、钠和钾的流失也明显更高。潜在原因应与体重和胃肠道之间的关系或食糜通过时间的差异有关，尤其是通过大肠的时间差异。
