Yes, a dog needs to ne taught to mind his manners.
A dog needs to give a warning bark when he hears something but to not teach your dog when enough is enough is not doing your dog any favors and reflects badly on YOU not the dog IMHO.
My German Shepherd, Dax, saved me many times not by barking but by his low throated growl, very scary and effective.

That would be scary. When Cooper growls he is serious. When he barks, usually it is frivolous. Sometime he’s excited that dad is home but usually it’s just to tell us that turkeys or deer are in the yard.
