Une exposition légère à modérée à la nicotine peut se produire lorsqu’un chat ou un chien grignote un patch de nicotine, mordillent de la gomme à mâcher à la nicotine, mangent une cigarette ou une petite quantité de tabac trouvée dans la maison. A moins qu’ils mangent un paquet entier de cigarettes, un sac complet de tabac, une boîte de patchs ou un paquet de gomme, la consommation de nicotine est relativement faible, mais non complètement inoffensive. Les cigarettes électroniques contiennent de la nicotine liquide qui est également absorbée par le système digestif des animaux mais peut aussi entrer dans le corps par d’autres moyens. La nicotine peut être absorbée par les muqueuses et la peau des animaux. Ces voies transmucosales d’absorption contournent le foie, de sorte que plus de nicotine atteint la circulation sanguine plus rapidement. Cela signifie que l’empoisonnement est plus élevé avec les cigarettes électroniques.
Mild to moderate exposure to nicotine can occur when dogs or cats nibble on a nicotine patch, chew on nicotine gum, consume a cigarette or eat a small amount of loose tobacco left lying around the house. Unless they eat an entire pack of cigarettes, a whole bag of tobacco, a box of patches or pack of gum, the nicotine consumption is relatively low, though not completely harmless. E-cigarettes contain liquid nicotine that is similarly absorbed through the digestive system of pets, but can enter the body by other means as well. Liquid nicotine can be absorbed through the mucous membranes and skin of pets. These trans-mucosal routes of absorption bypass the liver so more nicotine reaches the bloodstream faster. That means the risk of nicotine poisoning is greater with e-cigarettes.

There is a large number of infections that can be passed between species, however, simple hygiene and common sense will drastically reduce if not eliminate the risk of zoonotic spread of disease.

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.
It is best to avoid giving any vegetable from the onion or garlic family. They cause irritation of the gastrointestinal tract and destruction of red blood cells which, depending on quantity consumed, leads to severe anemia.
