Few things are more concerning than watching your dog try… and struggle.

They ask to go outside more often.
They squat repeatedly.
And little—or nothing—happens.

Cause #6: Pelvic Injury or Narrowing

Pain, posture difficulty, or underlying disease often made it harder for them to pass stool normally.

And once we addressed the real cause—
the symptom improved.
