Hello h:

If she's trained, then she may not be well. Take her to the vet.

How often has this happened? Was it a one time deal, or has it been going on for longer? If so, how long?

How old is your dog? Have there been any recent changes to her home? Is she fixed?

In other words, we need more info.

I'm having a similar problem. My daughter's 8 yr old schnoodle has pooped in the house once per visit the past 2 weekends she & the dog have been w/me and my 1 yr old schnoodle. The 1st time he did it immediately after I let him back in the house in response to his bark at the door. I've been told he's been doing this at their primary residence for a little while now. I've gotten the impression it's been going on for several months there. He was neutered and trained (both house and behavior) as a pup. He's been living predominantly in my Ex's home for nearly 2 years. I am not aware of any changes in either home environment which might upset him. His health appears to be fine - eating, drinking, relieving himself w/normal frequency and amounts, interacting w/people and other dogs in the same way, doesn't appear to be uncomfortable (NO itching, bottom scooting, restlessness, unusual sleepiness, irritability, etc.) Nor have I noticed any other changes in his behavior. Any ideas why he may be doing this and/or suggestions?
