Just read your other thread.... Does your brother wear the same style clothing and shoes all the time? Ask him to change up as a test, including hats and glasses, just to see if it's his appearance setting the dog off.
When he acts like this toward your brother, I would do an 'Ah, Ah' for interuption and a firm 'No'. If you get no response, I would confine him in another room, till he calms down, then bring him out. If he starts again, do the 'No' and back to confinement. If this is not possible, I'd put him on a leash and make him sit.
Does he act like this towards your brother when you're not there?
Once an excitable dog gets going, it can be hard to bring them back, so try to prevent it from starting in the first place. Reward good behavior, and physically block the bad, with the leash or the separate room. It can take months for a dog to learn to accept things that they aren't comfortable with. But, with repetition, it can be done. |
