My Mobie tries to pull this and I just tell her go to the bathroom. And I don;t let her back in until she has, I know the wet grass is not going to hurt her and I know she has to go to the bathroom so I do not back down.

i am so mean

It usually takes a little while but once she has understood that she will not be going back into the nice dry house until she has gone pee she will go all teh while giving me a pitiful look

Just put your foot down and make sure that they go to the bathroom when they are outside, sorry this is all tha advice I have. Oh yeah, one other thing I do is the minute Bobbie comes in I grap a towel and cuddle her in it while rubbing her down, she loves this and thinks it a great treat
