18 month old male shih tzu goes literally barking mad when he sees another dog. He will pull, bark constantly and won't calm down until out of sight or greeted dog.
He barks when he sees dogs from our balcony which I have put bamboo screening up but he still bloody sees through it.
I dread letting him off his lead even in fields as he runs for miles to get to another dog. He stops responding and will run across busy roads. He greets okay but if the other dog shows aggression he doesn't take the hint and will carry on til I drag him away.
Anyone have any advice?
