My husband and I adopted a 3rd pitbull in November of 2016. She is about a year old now. Things were great! We took her to training classes, the vet multiple times as she has had Giardia and demodex, and she seemed to be fully potty trained. Now she is refusing to poop outside and has done it in the house right in front of me. We do live in a snowy and cold climate during the winter months. We've tried the rubbing her nose in it and letting her know that's not ok. We make sure that the area is fully cleaned and washed and use the nature's miracle as well to get the smell out. I don't what else to do! Any suggestions?
