What this symptom means clinically

Difficulty defecating, or pain and straining during defecation, usually reflects impaired passage through the lower gastrointestinal tract, fecal retention, or local anorectal pain. It may be caused by hard stool, rectal or anal disease, pelvic or skeletal abnormalities, or neuromuscular coordination problems that affect propulsion and sphincter coordination.

🐱 In cats

Cats are more prone to fecal retention and painful defecation from hairballs, chronic colonic dysfunction, or megacolon, often showing frequent squatting or straining with small amounts of stool.

🐶 In dogs

Dogs often strain or show pain from anal sac obstruction, prostate disease, pelvic trauma, or neuromuscular problems, sometimes attempting frequently but passing little stool.

Clinical signs you can observe

Check whether your pet shows any of the signs below. If several apply, seek veterinary care promptly.

Record vocalization, facial expression changes, or obvious straining during defecation.
If tolerated, palpate the abdomen and anal area and record any firmness, swelling, or pain.
Record food and water intake over 24 hours to help assess intestinal motility.
