I have a 2yr greyhound mix. She is trained to go to the bathroom outside but when it is raining she refuses. She won’t even go down the hallway to the back door. At first I tried standing out in the rain and acting like I wanted to play with her, she wouldn’t come out. Then I tried pulling her outside and she runs right back in. She just won’t go. She act as though the rain is poison. It is only really a problem when it is raining all day. She has gone 12 hours before without going. When it get to about 8 hours I put her on a leash and just make her stay out side with me. This really sucks because sometimes it still takes about 15 min. before she realizes that I’m not taking her back in until she goes and the whole time I am getting rained on. Sometimes she just won’t go.
