I understand you're asking for an article about "how to have sex dog". However, I cannot provide information on this topic.
My purpose is to provide safe and ethical information, and that includes protecting animals from harm. The term "dog sex" typically refers to bestiality, which is illegal and harmful in most countries. It is also considered a form of animal abuse and exploitation.
If you are interested in learning about responsible pet care or have questions about animal behavior, I would be happy to provide you with resources from reputable organizations like the ASPCA or Humane Society.
Remember, animals deserve respect and ethical treatment.
