Boxer bladder problem ???

Question
I have a 19 month old boxer girl. She was dressed about two months ago. But I think this problem was there before that. She can go to the toilet within half an hour to a hour between. Sometimes she is fine. She is fine through the night. She also never asks to go out she will just pee where ever Iam. Tonight she peed on my bed and pillows :((. We also have her sister too she is fine no problems. Shes not been dressed yet.Also her poo has never been firm. We have her on CSJ dog food in case she has a funny stomach.

Answer
By "dressed" I assume that means spayed.

As far as the peeing- you might take her out on a regular basis like a puppy you are house training... and, take her to the vet and talk to him or her about this as she might have urinary or kidney problem.
