What are the shortcomings of Labrador that should be understood before reproduction?

My family is almost two years old and follows me silently every day, like a mute. This is the only drawback. Our family likes to be clean, but it has no smell. My lesbians like eye contact, which used to make me laugh and cry. For example, no matter how high she goes out to play, she won't leave the range of the owner 10 meter. Although she is playing, she will come and follow you as soon as she finds that you have gone a little far. There are really many advantages, and it is not aggressive to people. You can judge whether you are really angry or fake angry according to your tone. Teach it skills a few more times. Whether a dog feels good or not, whether it has shortcomings or not, requires the owner to make efforts to educate it. My own feeling is that after raising Labrador, I really don't want to raise another dog!
