The "Accident"

Well, last night my husband and I spent the night at my parent's house, which we do at least once or twice a month (more often now, since my dad just had surgery and can't move around too well yet). Ever since we got Rocky 2 years ago, we have spent the night there, and he's never been bad except for the time when he shredded some carpet to get out of a room. Other than that, he's been fine.

However, the last two times have been different.

Last time, we came over and were eating dinner with the family when suddenly we could smell something gross, which turned out to be poop on the hardwood floor near the table. We weren't sure if it was Rocky's or Bentley's (my brother's dog). It was a small amount, so we assumed Rocky, who is 15 lbs compared to Bentley's 30. However, both dogs were already laying in their beds, so since we didn't catch either in the act, we cleaned it up and kept an eye on both. Nothing else happened the rest of the night.

Now, last night was worse. We got to my parents and Bentley and Rocky greeted each other, which means Bentley tore around the house chasing Rocky, who wags his tail but seems annoyed with it, but once they settle down, they get along. Not five minutes later, my husband found poop on the tile floor in the kitchen while my mom was making dinner. Again, no one saw which dog it was, but it was a small pile. Again, we cleaned it up and kept an eye on the dogs. We instantly took Rocky outside to run, and he pooped, so we assumed it was Bentley.

At the end of the night, we got into bed after taking Rocky outside one last time. He peed, and this was around 12:30am. This dog never goes in the house now that we moved, and he goes outside at 7am then not again until about 5pm, again, never goes inside. So we are astonished to wake up to find he had just peed on the carpet in the guest bedroom at my parent's around 6am. Once we get out of the groggy state and realize that he had just done it, we also realize he had pooped in the same area as well.

Now, please keep in mind Rocky ALWAYS lets us know if he has to go out. He had been given a bone, which makes him go more often, but he always wakes us up to go out. Any advice/ideas anyone as to what is causing this the last two times at my parent's house? Anything is appreciated!
