So my GSD has always been an anxious/protective dog and barks. However lately she’s getting worse and is barking at everything and nothing. I get that barking normal, but I’m looking for training advice to get her to stop when I say stop. She’s a German shepherd, she’s going to bark and protect I get that; but she can just go on and on and I’d like her to stop when I tell her stop. I am thinking of maybe getting a professional to help, but we can’t afford one at the moment so any advice would be great. Thanks.
