Good grief, you really are dense if you think anyone is saying guns are the same as dogs.
Of course dogs don’t expel bullets and guns don’t bite.
What you don’t or refuse to see is the common factor involved.
Think about it!
Some folks are not adept at extrapolating.
There is no common factor. Dogs are capable of actions on their own without any human intervention. Guns are inanimate (note inanimate) objects.
