I do give her a treat everytime she does good and I give her tons of affection and everything I do also go out in the yard with her we don't walk them because of the size of our backyard

I have a 7 month old tri-color basenji female and she is having a hard time getting house broken, anytime she goes outside she will stand at the door to go back inside she doesn't like to walk around outside, any time I catch her in the act I stop her show her what she did give her a firm spank and put her outside for about 15 minutes. And she doesn't seem to learn, she doesn't seem effected by it, I have a 4 year old red n white female and a 8 month old red and white male both are housebroken, I figured she might catch on with the other dogs but she hasent, I've tried crating her at night and she just yodels constantly and. Can't slleep I've tried brining the crate into my room and putting it next to my bed thinking that her being away from me was the reason she was yodeling, I've tried picking up her messes and putting the outside and bringing her out with it to show her where its supposed to be, but she doesn't seem likeshe realizes she's doing anything wrong like if you discipline her she just looks at you like "wtf?" And the puppy pads she just tears up I need help I am 100 times over my frustration point
