Oh...actually, I forgot the BIG one

 . When Max was only about 9 mos old, we took him with us to my mom's for Christmas. He was ALMOST completely housetrained (at least at OUR house), but we live in the desert and hadn't had ANY rain...so Max had no idea what it even was. We get to Napa, and it's pouring almost the entire time, and COLD outside, which he also wasn't accustomed to. So, I had a feeling that an "accident" could be within the realm of possibility.  My dh and I ran a tag-team of spotting Max's little piles on the carpet and one of us would distract my mom or stepdad and the other would clean up the mess, so they wouldnt' be upset or think Max wasn't a good doggy, LOL. And we did pretty well until......
 I told my mom and my stepdad to make SURE when they went to bed  to close all the doors to the other bedrooms so that Max couldn't "disappear" in there....which I knew he'd go into a bedroom where it was nice and private and warm to poop if he had the option between that and going outside where it was all cold and wet and drippy.   
So, next morning, what happens? My ADD stepdad had neglected to shut the office door, and he went in there, and stepped, in his sock-clad feet. into a pile of gooshy poop

 . BUSTED. I have to admit, my husband and I were nearly apoplectic with laughter over it....after all, we DID warn him

 . But it was a little rude of Max anyhow, LOL.
