When I just went to the bathroom to pee, I found a small white spot on yinjing, like a thick one

Dear, this is a normal physiological imagination, don't worry, in my time (my 70s), my classmates also had aunts in the fourth or fifth grade of elementary school. Talk to your mom and she'll teach you how to handle it.

Lock the bathroom when it wants to pee, and when it finishes peeing, put it in the nest you made for it (don't care about it if you don't obey it), and after a while it wants to run back and stay and hit it, (don't break it). >>>More

You should see where the dog's last poop is, wrap its poop in newspaper and put it in the bathroom, then grab the dog and let it smell its poop, while telling it in a serious tone that it should poop here, and use disinfectant to remove the smell of the place where it often poops now. Teach it for a few days in a row, and it will change, and you must hold it to smell it, and if you don't want to, you have to force it to hold it and smell it. My previous dog also recognized the poop in the right corner of the balcony, even if it was uncomfortable, it had to go to the balcony to pull, that is, to get its poop to the bathroom and then catch him to smell it quickly changed.

Heart problems can lead to fainting. It is recommended to go to the hospital for a comprehensive examination as soon as possible, and the sooner the problem is found, the easier it is to treat.

If you don't listen, train it, when it pees, close it in the bathroom, or when you pee yourself, open the door for the dog to see, and train it dozens of times.
