I have a 4 year old mixed breed dog. She sleeps on the floor in the room with us. For the last couple of months, she has been pooping on the floor overnight while we sleep. Its not every night, but pretty close, I'd say
4 to 5 nights per week sometimes. We have tried keeping her in her cratesometimes, and sometimes she will even go in there while we are not home during the day.
The poop is often not diarrhea, but is still much softer than normal poop would be...its definitely not solid. And sometimes appears to have a clear, mucus like substance mixed in with it.
I don't understand why, if she had to poop, she would not whine or cry or try to wake us up (which is what she used to do).
Is it possible that there is a medical reason for this, or is this a behavior thing?

It sounds like your dog could have colitis or IBS. My dog suffers from colitis due to food allergy and is on a special diet but it can be caused by internal parasites. It would be best to see a vet. It is painful and he might not have enough time to warn you so it is not his fault.Emotion: sad

Alison pointed out that it could be a medical condition. It could also be incontinence setting in. Elderly dogs are as prone to incontinence as elderly people and it doesn't always have to mean urinary incontinence. The feeling that they have to go can be subdued until its literally time to go NOW and/or they just no longer have the muscle strength to hold their bowel for long periods of time. I don't know if this is worth anything but two rescue dogs who had bowel incontinence, due to spine & pelvic issues, both had soft stools for "accidents." One would leave little turds behind whenever he slept, not even realizing he was having a movement while he was relaxed.

As Alison suggested, see your vet. Get a stool sample before you go - I'm sure the vet will ask for one. The mucus isn't normally seen in healthy poop.
It could also be a food sensitivity. One of my chihuahuas has sensitive bowels. He does very well on plain kibble, or kibble mixed with a teaspoon of dog food, but we take a chance of triggering an attack of loose bowels or diarrhea if we augment his diet with treats, esp. human food. (Once we figured out the connection, we don't do that anymore.) A

This seems unlikely to me in a four-year old.
I'd get the dog to the vet for a check-up.

You're right, I somehow missed the 4yo and thought the dog was elderly. I have absolutely no idea where I got that from though.

You probably just subconsciously read "14" instead of "4". Happens to me all the time.

She was caught unawares. As others have said, this is likely a medical issue.
