I have had my dog ever since he was a puppy, happy lovely dog. Now he is 6, and his attitude has changed. He gets more aggressive over the smallest things. He has to sleep in a dog crate when I go to work after he destroyed my kitchen, ripping of the wallpaper and plaster. I decide to open up the cupboard under the stairs, so I could make a room, which was his. I put his crate in their and his food and water bowl. Everything started OK, and then he got worst. He knows when its time to go to work even though I try and change my hours, he'll run away and growl and try to bite me. I got told it was anxiety, so I have been trying to distant myself, to show him I am top dog. This has not worked and I’m at the end of my tether.
Can anyone help me please?
