Re: Pooping behavior

So, we have had our Ginger for about 7 mos now and we are curious about some things.
1st - she absolutely loves peeing in a bush. I mean she will crawl right up into it and then relieve herself. This doesn't happen every time, only about 85% of the time. Is this normal for this breed?
2nd - she will squat-walk while she is going #2. She will never just squat in one place. Is this normal?
3rd - if it is raining out, she will hold everything in until she can't. We do try to take her out in just a mist, and it is a struggle. Only when she can't hold it anymore will she go out, and it is only to pee. She refuses to walk to her pooping ground. Living in the Pac NW, rain can be continuous for 1 - 2 days. This concerns us. Is this normal?
4th - we have her on a gluten and grain free diet, would this be the reason why she doesn't have to poop as often? I have noticed that if we feed her a bit of dinner scraps (not a lot by any means), she also seems to have a bit of a looser pooh and will pooh 3 - 4 times in one walk.
Any info from experienced owners or noobs like me would be appreciated.
