Yorkies make good guard dogs, not because of their formidable size or powerful bodies, but because they are smart, courageous, and fiercely loyal.
The problem is when they bark for non-defensive purposes.
The first step in curbing the Yorkie barking problems is to properly train your dog. Your Yorkie needs to be trained at any early age (starting around 8 weeks) and you must establish yourself as the alpha pack leader. If you don’t, your sweet and tiny Yorkie will happily snatch the position away from you, and this will be problematic down the road. For example, if your Yorkie thinks he/she is the alpha pack leader, he/she will assume it is their job to bark at whatever could possibly threaten the home. Thus, you can end up with a dog that barks at everything that walks by.
Training should involve reducing or eliminating separation anxiety. Separation anxiety, which occurs whenever you leave or come home, and can continue to manifest itself while you are gone, can lead to excessive barking. You will want to make sure your Yorkie doesn’t feel that anxiety when you come and go. This involves not giving your dog attention when you are coming or going from the home.
Another method of eliminating unnecessary Yorkie bark problems is to reduce your dog’s ability to see outside of the home. This could entail putting in a fence that prevents your Yorkie from seeing the street and sidewalk outside. It could also entail closing blinds or curtains so your Yorkie doesn’t feel the need to jump up and bark at everything that walks by.
You should also try to distinguish between barks. Dogs bark for different reasons. Some Yorkie bark will be purposeful. For example, they are barking at an intruder. Other types of barks may be unnecessary and purely emotion, like when they bark out of boredom. Thus, you will aim to discourage the “bad” barking (like the kind they do due to separation anxiety), and not necessarily reprimand your dog for the “good” barking.
Whining can be a sign of distress. The best approach is to look over your dog to make sure they are not in pain, and if it is just some other kind of mental distress that can be dealt with by following a training method. Yorkie bark doesn’t have to be a problem. Be proactive and this will help to alleviate the stress of a barking dog.
