This is a normal thing. After all, dogs evolved from wolves, so they will retain some of the habits of wolves. In addition to howling, they can also hide food, dig nests, and eat. Parents should not pay too much attention to the grass and other wolf-like behaviors if they find it. This will not affect its normal life.
Tip:
Dogs also inherit the hierarchical consciousness of wolves. When raising them, parents must let them understand that people have a higher level than them, otherwise they may become arrogant.
