你知道吗，狗狗身上的细菌不仅能通过唾液、粪便和飞沫传播给人，还可能通过它们的毛发和皮肤来传播疾病。比如说，如果你的狗有狂犬病，它咬伤你时，你就会被感染。如果你的狗得了结核或是某些类型的细菌性疾病，它们排泄物中的病原体可能会污染你的食物、水或者其他东西，从而让这些疾病传给你。甚至于，一些寄生虫也可以通过粪便传播。而且，当一个带有感冒或流感的狗打喷嚏时，它就像散布了一种致命的“飞沫”，这也是一种常见的传染途径。

此外，dog's fur and skin often harbor various viruses, bacteria, mites, lice and other pathogens. If you're not careful, you could catch diseases from them by hugging or kissing your dog too closely.

So it's important for dog owners to learn about zoonotic diseases – the ones that can be transmitted between animals and humans – and take steps to prevent the spread of these illnesses. This might include getting your pet vaccinated against certain diseases, avoiding close contact with them when they're sick, and keeping their living space clean.

By being aware of these risks and taking precautions, you can help keep yourself and your furry friends healthy.
