Hey, as some of you know, we have a new dog called sunny.

When ever my mum leaves the house, he chases the fence in the garden and starts to whine. I take him in and pet him and play with him in the garden. But he's not happy 50% of the time.

He just goes to sleep, doesn't want to be disturbed, and rejects us when we call him, when we're 2 meters away and won't play with his toys, till mum gets back. Is this normal?
