Hello everyone!

I'm hoping you can help with a little issue I'm having. I have a 5 year old australian cattle dog/german shepherd mix. We adopted him from a shelter about 4 years ago. He's a wonderful dog, playful, affectionate, and intelligent.

At night, however, he wants nothing to do with us, especially me. If I approach him he growls and postures. This can happen anywhere, if he's lying on the floor or on the bed, in the bedroom or in the kitchen. Come morning he's fine again, showering me with kisses and tail raised high.

Any thoughts?

Thanks!

Norm
