Inflammatory bowel disease (IBD) occurs when a dog’s stomach and/or intestine becomes home to an unusually high number of inflammatory cells. These cells cause changes in the lining of the digestive tract, which inhibit the normal absorption and passage of food.
It is important to note that although some of the symptoms may be similar, IBD is not the same as irritable bowel syndrome, which is caused by psychological stress rather than a physiological abnormality.
Signs that your dog is experiencing painful defecation include
Barking, whining, or other unusual noises while trying to defecate
Straining to defecate and not producing any stool
Blood at your dog's anus
Mucous, tarry, or thin, ribbon-like stool
If your dog is straining to defecate and is vomiting, or if there's blood in the stool or around the anus, always see your vet right away as these could be signs of a serious problem and may lead to shock if left untreated.
What’s Causing Your Dog’s Pain?
Common causes of painful defecation in dogs include:
Symptoms of diarrhea are pretty easy to spot: loose, liquid, or frequent stools. As with so many conditions, treatment depends on the cause of the diarrhea and may include dietary changes, fluid therapy to prevent dehydration, and occasionally antibiotics if an infection is identified.
Get your dog vet care right away if he has more than one episode of diarrhea, is lethargic, has a fever, blood in the stool, or black, tarry stool.
Like diarrhea, constipation in dogs can be caused by a wide range of things, including certain drugs, intestinal obstruction, enlarged prostate or lymph nodes, dehydration, tumors, and neuromuscular problems.
Signs of constipation include: straining to defecate; firm, dry or ribbon-like feces; depression; lethargy; vomiting; loss of appetite; and stomach pain. Treating constipation depends on its cause, though for mild constipation a high-fiber diet, plenty of water, and laxatives as prescribed by your vet may be all the treatment needed.
If the constipation is serious, manual removal of impacted feces under general anesthesia may be necessary.
