Hi, I have just own the male and female pit-bull in the last month. I have just adopt them from my near shelter, they are young, but some how adjust in my home. But now I am afraid, last day they are just stuck during mating. I don't have any experience of the dog mating. I have just search on internet, and found that it's a normal part of the dog's mating process. Let me know your thoughts about this process.
