My pet dog

My pet dog’s name is Black Bean. She is a Border Collie, has black and white fur, and is one and a half years old. Actually, sShe was a stray. I saw her for the first time in the street. She was very dirty, with a flurried expression on her face. I called her, then she saw me and went to me slowly. I was a little afraid, so I went away. But she followed me all the time . Perhaps this is providence so I decided to adopt her. I brought her home . She likes my home very much.
She was excited to visit everywhere when she just got home. I’ve loved small animals since I was little and always wanted to keep a pet .But she came too suddenly, I was not prepared at all. I did not know how to keep a dog so I made a lot of mistakes. She was only five months when I adopted her. She is very naughty, flutters, shits and pees everywhere, bites the furniture, dumps buckets, steals socks, etc. She really annoys me.
I searched for some knowledge of dog training on the internet. First and most importantly, to train her to toilet on the dog toilet. I tried every method to get her to the dog toilet, but with no effect. She did not run away or sat down when she got here. After I go away, she defecates where she likes. Finally, I could not bear it. I decided to lock her in the toilet until she defecates in the right place. I had to wait four hours every day , and it lasted for a week. At last, she has learned. She is so clever. She can get rewards after she defecates, so she learned how to get more rewards. She always goes to the toilet now. She treats the toilet as a snack vending machine. Every time she asks me for a reward proudly after doing her business, she is like saying, “Look! I defecate, I’m so good!”
Black Bean is a nice dog. She loves me especially. When I am sad, she comforts me; when I am alone, she will be with me. She is my pistachio. I have been very happy every day since she came to my home. I hope she can accompany me forever.
