Our watchdog is very good

Our Labrador dog has been with our family for ten years. During these ten years, she has been very loyal and has protected my children. As a guard dog in my family, he is very good. Now he is too old to do what he wants, but I will still regard him as a treasure in my heart, because nothing can replace his ten-year relationship. I also hope that he will be a happy dog in our family. I don't know what pets have been with you for the longest time. You can share it with me in the comment area~
