“He’s started barking at people he knows”

Many teenage dogs go through this. Often it isn’t the person at all, but the situation, and once you know which one, you can help.

Illustration: a young dog sniffing the shoe of a visitor who sits calmly on the sofa.

Your neighbour, your sister, even your partner coming home late: people he’s known since he was tiny, and suddenly he’s barking at them, backing away with his hackles up, or won’t let them in the door. It’s upsetting, and a bit embarrassing.

As they mature, some dogs become more watchful about who comes and goes, especially at home, and some become warier of particular things people do. Often it’s the situation that matters: the doorbell, someone arriving in the dark, a hood or hat, a loud voice, someone bending over him, or reaching for him before he’s ready.

Notice the pattern

For a week, jot down who, where and when. Is it only at the front door? Only with men, or with people wearing hats or carrying bags? Only in the evening? Is he barking and backing away (worried), or barking and pulling towards them (frustrated, desperate to say hello)? The pattern tells you what to work on.

Make arrivals easier

  • Give him space when people arrive. A baby gate, a lead, or a quiet room with something to chew means he doesn’t have to face visitors at the door. Bring him out once everyone has settled.
  • Ask visitors to ignore him. No looking at him, leaning over him or reaching to stroke him. Let them toss a treat away from themselves and let him choose whether to come closer.
  • Keep it short and sweet. A few minutes going well is better than an hour that ends in barking. Let him go back to his space whenever he wants.
  • Say “Thank you!” when he barks at the door, and go together to a spot away from it where good things happen.

Never make him “say hello”

Pushing a worried dog towards someone, holding him while they stroke him, or telling him off for barking can make him more sure that people are a problem. Let him set the pace.

Check his health

Pain can make any dog grumpier about being approached or touched, so a vet check is worth it. Mention any other changes. Hormonal changes can also play a part, and whether or when to neuter is something to talk through with your vet.

When to ask for help

Get help straight away if he has nipped or bitten, if children are involved, or if it’s getting worse or spreading to more people. Barking at familiar people can have several different causes, and getting the reason right makes all the difference.
