TL;DR: Dog constipation is a common digestive issue that causes discomfort and bloating; while typically not a life-threatening emergency within the first 48 hours, you should consult a veterinarian within 24 hours to prevent serious intestinal blockages.
What exactly is dog constipation and how does it affect my pet?
Dog constipation is a common digestive issue where a pet has difficulty passing stool or stops having bowel movements altogether. After two days without a bowel movement, the waste in the colon typically becomes dry, hard, and difficult to pass, causing your dog significant discomfort and bloating.
Is it a medical emergency if my dog has not pooped in two days?
- The urgency level for a dog that has not pooped in two days is considered Medium.
- While it is not usually a life-threatening emergency in the first 48 hours, it requires prompt attention to ensure the condition does not worsen.
- You should schedule an appointment with your veterinarian within the next 24 hours to prevent the condition from progressing to a more serious impaction or an intestinal blockage.
Why should I provide my veterinarian with a photo or video for triage?
- If your dog has passed any small or unusual pieces of stool, a photo of the consistency, color, and size helps the vet determine the severity.
- A photo or video of your dog's posture while straining helps the vet distinguish between true constipation and other issues, such as a urinary tract obstruction or inflammation of the anal glands.
- Providing visual evidence serves as a vital diagnostic tool to help your vet provide the most accurate triage advice.
Clinical Context (Merck Veterinary Manual)
The classic clinical signs of constipation are tenesmus and the passage of firm, dry feces; if passage is hindered by an enlarged prostate or sublumbar lymph nodes, feces may appear thin or "ribbon-like". Animals may exhibit lethargy, depression, anorexia, vomiting, and abdominal discomfort. A history of dietary indiscretion and physical evidence of retained feces confirms the diagnosis; duration and influencing factors help determine the cause. Plain abdominal radiographs may help establish the inciting factors and fecal contents. A CBC, biochemical profile, serum T4 level, urinalysis, and neurologic examination should be completed in cases of chronic or recurring constipation.
