We got a 1 year old female ausie/border collie/springer spaniel (we think ?) from the friends of animals about 9 weeks ago. She is very smart, and we have fallen in love with her. The problem we are having start 2 weeks ago when we took a car trip for several days, the dog would not go to the bathroom anywhere! We tried for hours to get her to eliminate, and she finally went in the hotel room, about 16 hours after we had left the house. We ended our trip early, and drove back home, where she went the next 18 hours before she went potty again. She seems to only go in the backyard of our home. I have tried moving some of her poop to front yard, and that hasn't worked. So i have started treating and praising when she eliminates in the backyard, as well as establishing potty, and poop comands when she goes. the problem now is she is starting to pee in the house! she didn't potty in the house for the first 2 months, and now is peeing on the rug! HELP! ?
