[spikey]

Spikey turned 10 months old on 7 May. When he was a puppy, he never barked at strangers and was a sweet little thing. Now, he will bark at anyone when we take him for walks. He will also bark at people when he is in the car and I'm holding him. Sometimes he even growl.
I often have to tell him "no barking" 2 times before he will stop. It is very embarrassing when I take him for walks and he will bark at every single soul that walk past us. He doesn't bark non-stop but he will bark once. The only time when he doesn't bark at them is when the person never give him any eye contact. I won't consider him agressive but just behaving like a "terrier"
He is pretty shy with other dogs and show no interest to play with other dogs. I've tried the coins in the container. I've tried holding his mouth and tell him no barking. He will stop for a while, then he will start all over again.

I wonder if this is yorkie's nature.
