I can't count the amount of times I have told my dog to get out of my room. She used to come in only when I allowed her to, as most of the time my door is closed. The tone of voice I use to tell her to get out has grown from a stern "No" to a "Keilah!!!!" I try not to be "emotional" about it or get mad, but I know she can sense my frustration with her. She can't seem to get her head around the fact I don't want her in my room.

She knows she is not allowed in other parts of the house, such as upstairs, kitchen, bathrooms, and the guest rooms. She is a dominant dog and we don't want her overcoming us and taking over. I practice small dominant exercises such as going ahead of her in hallways or when we walk together, through doors and down/up stairs, and she totally takes to that. On command she will walk behind me or heel off leash for her entire walk. She isn't a stupid dog, but she is almost 11 so maybe she has short term memory?

She has full run of a part of the middle floor and half of the basement, so we're not totally locking her up or anything.

I must be doing something wrong. She knows these things but does not listen. She knows she's not allowed but does it anyway. What can I do? Should I just keep my room's door closed and not cause her any more stress?

Does she need something? such as to be let out?

What have you tried to remind her to stay out of your room (other than yelling/getting frustrated)?

What kind of dog is it? Are other dogs in the household allowed in that room?

many dogs are not great at generalizing. They don't get "sometimes" - it's either I am allowed in or I'm not.

This MAY sound a bit sappy but she's older and maybe just maybe she wants a little company a quick pat on the head and to be told that even though she's old she's still wanted.

Possible that you are spending less time with her and she wants some attention?

Yes.

She does not "know these things but not listen."

She knows that sometimes when she goes there she is yelled at for a mysterious reason, and sometimes not.

She has not been trained not to go there.

Baby gates are a great tool for managing the rooms your dog can and can not enter.

Or, a piece of tape across the carpet.

A dog can be taught to obey a visual barrier, PROVIDED it is CONSISTANT.

If the line of tape on the floor always means the room is off limits, then the dog will obey.

We've done that with Danke so that we can make rooms "temporarily" off limits.
She just knows tape on the floor means Stay Out. No tape, come on in.

I used a piece of yarn at the dogs shoulder level to keep mine out of the kitchen. I taped it up between two walls (easily removed when needed). This worked nicely because there was also a carpet/wood floor change in the spot as well. Once the "rule" was established we were able to make it without the sting. Seems silly, but it worked.

We actually learned this accidentally.

My son (ah, boys) decided when he was about 2 1/2 that he wanted to rip his carpet up (Mommy was at work... Daddy was not paying attention). He started at the seam between the carpet in the hall and his room.

We used tape where he'd pulled the carpet up, as he kept catching his feet on it and tripping.

Because Danke has NEVER been allowed in his room, she associated the tape with "Off Limits!".
A few months ago, I was taping loose straps on my field gear, and had strands of tape laid out on the floor. It was then we realized that her mental association, and we decided to take advantage.

I do something like Alyssa. When I train change of position, I use a visual reference to prevent "creep". In my case, I use a water toy "noodle" (long styrofoam-like tube) cut in half. The dog is taught that all fun things (treats, toys, play) happen on one side and the other side is to be avoided. If they touch or cross the line, I tap the leg or toe with the "noodle". It doesn't hurt but they find it annoying and comply. It is easy then to carry this tool("noodle") into other uses and can be used to signal that a particular room is off-limits now by laying it on the floor at the entry to that room.

Too late to edit, but once the rule was established we could take off the STRING . I like the tape idea and they have all kinds of painters tape that doesn't stick like duct tape and is easily removed.
