How Dogs Say Hello
When a dog sees its owner, it often shows happiness in a few ways. First, it jumps around and wags its tail. This is like a dog saying, 'I'm so happy to see you!' The tail wagging means the dog is excited and friendly.
Why Dogs Bark at Strangers
Sometimes, dogs bark at people they don't know. This is because they want to protect their home and their family. When a dog barks, it is trying to say, 'Who are you?' or 'Stay away!' Even though it might look scary, it’s just the dog's way of being careful.
What You Should Do
If you see a dog that is barking, it is best to stay back and let the dog feel safe. Wait until the owner says it's okay to come closer.
Conclusion
So remember, when a dog jumps and wags its tail, it is being friendly and happy to see someone it loves. But when it barks at a stranger, it's just being cautious and protective.
