I said yes to this, because I have, but let me also say that I only do it if the weather is cool and I open the windows for her. AND it is only if its a quick trip in and out. No long wait time,etc. I rarely do this because I have a fear (logical or not) that I will come out to find that someone has taken her! During the hot months (and for Central Texas that is A LOT OF MONTHS) I don't do that AT ALL. If I take her anywhere in the warmer months I always take her out with me and that means a trip to the groomers or to go visit grandma and grandpa!
