Our Cockapoo Is 9 Months Old…very Cute, But…?

she is still not really potty trained. She will do #1 and #2 outside, and we take her out often throughout the day, but she also goes on the carpet in our dining room about once a day. I even put a motion detector in there and it works, but when I turn off the motion detector, she goes ahead and helps herself to pooping or peeing in our dining room! It’s like her day isn’t complete without it. I also have a carpet shampooer so I clean it up each and every time in this way, and we use “no go” spray all around. Does she just not respect us as her owner, is she just a high strung puppy that will outgrow it, or is there something else going on? We do have a kennel for her, but I really don’t like the whole “crate” philosophy. Any suggestions are appreciated.
