For the past couple of weeks my dog has been doing strange things in the house, the other week in the evening upstair in the hallway he started growling at the wall, his tail was sticking up in the air and his hair on his back was standing on end. I told him to stop and blocked his view but he moved across and started to do it again then that was it until the other day in the morning in the kitchen he came to me to have his belly rubbed so I made a fuss as usual. As I was making a coffee he was by the fridge and he laid down on his back on his own for a couple of minutes as if some one was fussing him he has never done that before only when he is play with a toy or with humans. Also some of my stuff have gone missing like my car key I normally place it on the side next to the phone as always but its disappeared, there I no one else living here just me and my dog.
