So we got a good bit of snow yesterday here in MD and a pretty thick layer of ice on top of it along with extremely cold weather overnight to make it nice and hard. I tried to take Cali out to do her potty and she was slipping and sliding all over the place and just kept pacing around but refuses to go to the bathroom. I am going to keep trying to take her out until she goes, but I just wanted to make sure that its not going to do her any harm to hold it longer then normal. She has not been out since around 7pm last night and it is now 5:30am! She is not acting like she has to go as she is resting on the couch watching the morning news, but I know she is due. My gf took her out at around 11 and 12 last night but she would not go. Ice and snow is a new thing to her so I just don't know what to do! I tried carrying her to her usual "spot" but she just slid her way back up to the house. The ice is crazy here,.. I am slipping and sliding across the top of the frozen snow without falling through and I am a solid 180lbs! 

It's the only way she will go I had to do the same for Jewel and Tasha. I did it mainly because the snow ends up so deep up here in the Mountains. This way I can also keep track as to their habits and be certain their is no problem developing with decreased urine or darker urine etc.
It does work though. Good luck !
