I have a 9 month old rottie/lab and she only pees in the house when we are home she does not go to the door she will just go anywhere and she won't stop even when I catch her? When we go out she never goes I the house ever!

A 9 month old should be housebroken by now.
When did you get her?
Could she have a UTI (did it start happening suddenly)?
When you say 'when we go out she doesn't go in the house' is she with you, or do you mean when she's home alone?

She needs patient training. Start a schedule to go out with her to go, at the same times of the day, every day. Dogs love routine. Try 4 times a day at first. As time goes by, you can let her out when she wants, but for now, she needs to be encouraged to go outside with you at exact times, praising her every move, with great exaggeration. Apparently she likes to go with you around!

Clean the spots where she has gone in the house, and cover them with something super perfumey like cheap cologne. You don't want her smelling those spots.

Reduce the areas of the house she has access to dramatically til she is trained, closing all the doors and blocking other places. Kitchen and living room only if possible, or even just the living room.

Yes when she is home alone she is fine! I got her at 8 weeks took a while to break her she was good for a month or so and slowly getting worse

Also it starting happening a bit more since she has been spayed a few weeks ago! I have the sliding door open all day long so she can go out
When she needs to and she never goes in the same spot twice. She also is always in the same room as me even if I catch her she won't stop until she's done

Do you leave her out when you leave or crate her/confine her to one area? Does she have accidents at night?

Did you use paper or potty pads when training or just after she came home from the surgery?

I would have the vet check and make certain she is healthy. Then start potty training again.

Taking her out after she wakes up, every half hour to an hour or limiting when she gets water and taking her out a half an hour after drinking, you get the idea and know the drill about praise. "Umbilical Training" where you have a leash attached to the dog and yourself so that you can tell when the dog needs to go and getting her outside immediately, might be an option.This time, give her an area where you want her to go potty. As she gets used to going to the area begin removing your presence as she potties. I think she may be going in the house because that is where you are. As she progresses, send her outside to do her business and praise when she comes in.

Use a good cleaner to neutralize the odor in the house. Don't try to mask it. If you catch her, say no and walk outside. I am guessing she is too big to pick up and carry outside. You could put a leash on her and take her out, but if she resists that could make her scared of the leash.

Good luck. You have a great mix for dog who wants to please. She just needs to understand what you want.
