Oh yes dogs barking, that’s why we moved from the other house. It can be extremely annoying. You can actually teach dogs not to bark, Cooper understands “no bark”. And then when he forgets or it’s too excited to listen to me, he really understands when I yell “shut up”. He taught himself that one.
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.
Ha!
