If your Shih Tzu barks or acts overly fearful of other dogs when out for walks, you're not alone. This is very common.
There are some easy yet effective techniques that can help. It's important to note that while these may seem simple, these work very well when followed to a tee.
#1. Have your Shih Tzu on leash and harness.
A harness is always suggested for this breed to prevent collapsed trachea and breathing issues; however, when training a Shih Tzu to tolerate other dogs, it is also vital.
A harness will allow you better control, you'll be able to reel your puppy or dog to you without risking neck injury, and the tension that travels from the leash to the harness sends more apt signals that those that would be directed only to the leash.
If you do not yet have a harness for your Shih Tzu, there are some great choices that are both comfort and come in a range of adjustable sizes to fit both puppies and adults.
