Despite the huge variety in coat color, the two basic pigments that determine the color of canines are eumelanin (black) and phaeomelanin (red). All different variations in color are created by these two pigments, which are both forms of melanin.

Il y a eu de nombreuses théories quant à la raison pour laquelle les chiens mangent de l’herbe, mais très peu de recherches. Toutefois, dans une étude menée à l’université UC Davis,
les chercheurs ont constaté que 68% des chiens mangeaient de l’herbe sur une base quotidienne ou hebdomadaire. Seulement 8% montraient fréquemment des signes de maladie avant d’en ingérer et 22% vomissaient après. Chez ces chiens mangeurs d’herbe, ils ont constaté que c’était les jeunes qui en mangeaient plus fréquemment et ils ne paraissaient pas malades avant, et ne vomissaient pas après. La recherche a cependant constaté qu’un chien qui semblait malade avant de manger de l’herbe était plus susceptible de vomir après.
There have been many theories as to why dogs do this, but very little research. However, in one study conducted at UC Davis University, researchers found that grass eating was common since 68% of dogs ate grass on a daily or weekly basis. Only 8% of dogs frequently showed signs of illness before eating grass and only 22% of dogs regularly vomited afterwards. In the grass eating dog population they found that it was the younger dogs who ate grass most frequently and they were less likely to appear sick before or to vomit afterwards. The research did find, however, that if a dog showed signs of illness before eating grass it was more likely to vomit afterwards.
