Canine behaviourist and trainer not associated with k9 training institute in any way. Do not put your hands near her you may be bitten Use a high value reward to lure her away, use a command such as "here" as she leaves the item and when she gets to you, praise, give her the reward repeat. On a chair. Again use a high value treat to lure her off. At the exact moment she has all 4 feet off give her the reward, say off and praise her. Repeat as necessary. If it is always the same chair put a box or something on it so she can't get on it. If not too heavy you can use the back of the chair to lift the back and GENTLY tip her off the front. Do not get involved in a confrontation. If she is guarding the dishwasher etc often consider keeping her on a trailing lead which you can use to draw her away. Without putting your hand near her mouth or challenging her in any way. Always command. Reward and praise when she is where you want her to be. Do not leave her unattended with a trailing lead. She could get caught up and hurt herself. If she has something in her mouth you want back. Swap it for something she can have. Like a treat (has to be high value to her). At the instant she lets go. Say leave or mine and give her the treat. Again. Do not confront. Just be calm and pleasant. You are changing the situation from confrontation. To getting her to volunteer a different behaviour and be praised for it. Simply put. Use your brain to achieve the action you want from her without force or confrontation, Name the action.at the exact moment she does it. (the command) reward and praise. What is now happening is that you are NOT stopping her doing something by telling her off and putting her in the wrong, you are gaining her compliance in doing something else on command and she is rewarded for being clever. Teaching her the "leave it" command would be useful. Google how to do that. As it would get rather wordy to try to explain in words here. All the very best with her. Kathryn
