" Dogs and constipation is a clinical irregularity of the digestive system in which an excessive volume of water gets absorbed from the colon. Water in the colon helps feces pass through the large intestine. If feces remains longer in the colon, it becomes dried and harder, resulting in a severe clinical problem called “obstipation”. Obstipation is an intractable form of dog constipation. Intraluminal (inside GI Tract), extraluminal (Outside factors) and intrinsic (neuromuscular) factors are the main cause for dog constipation. Diagnosis is usually through the clinical signs and a rectal examination. Dog constipation is usually easy to rectify. Affected dogs must be hydrated, dietary adjustments made, plus the use of laxatives and enema solutions. A surgical colectomy may be required in chronic cases. "
Dogs and constipation may be caused by any interluminal, extraluminal or Neuromuscular factors in the gastrointestinal tract.
A simple clinical examination and dietary history is usually enough to diagnose dogs and constipation. In terms of determining the cause, referred to as differentiation, several procedures may be required to identify the exact cause. Radiography may help in diagnosing any obstruction, tumor, hyperplasia or defect in the pelvis. Recurring constipation is more common in dogs with neuromuscular disorders. Neurological tests therefore are recommended in chronic, recurring cases.
Most cases of dogs and constipation treatment usually are usually rectified with the intake of large volumes of water and changes in the diet. Constipated dogs should be fed highly digestible fiber accompanied by a significant amount of water to drink. Consider a dog food that is 7% to 13% fiber such as Hill Prescription Diet w/d.
Laxatives can be used along with dietary adjustment. Laxatives are identified used as a lubricant to enhance and regulate bowl movements. Laxative should never be used in dehydrated dogs. Laxatives soften fecal material, forms bulk and improves contractility.
Docusate sodium and docusate calcium at dose rate of 50 mg capsules for 2 – 3 days act as an effective emollient or moisturizing laxative. Laxtulose at the dose rate of 0.5 mL/Kg, per oral is considered as an osmotic laxative, which retains water in the colon and thus softens feces and improves bowl movements. Bisacodyl at a dose rate of 5 – 20 mg if used, depends upon the size of dog, and acts as stimulant laxative, increasing the propulsive activity of the bowel muscles. Stimulant laxatives should never be used in dogs with an obstruction of the GI Tract.
An enema solution is used to moisten fecal material and initiate a bowel movement. A practical and effective approach is the use of warm isotonic saline or tap water, containing mild soap at the rate of 5 mL/Kg may be introduced in the rectum. Docusate sodium can be added to this solution in severe cases. Some toxicities and side effects are associated with the use enema solutions, such as depression, ataxia (failure of muscle coordination), and hemorrhagic diarrhea (bloody).
If the dog constipation is chronic and does not respond to medical treatment, a colectomy is indicated. Colectomy is a surgical operation of the colon by either resection (surgical removal of part of the colon) or correction of any abnormality of surgical importance. Colectomy is used in the case of injuries, neuromuscular disorders, tumors or pelvic disorders associated with the colon.In order to prevent dog constipation symptoms or its recurrence, dog food must contain highly digestible fiber, access to drinking water and a dog must be allowed to defecate frequently. Also follow some of the home remedies for dog constipation tips and make it a part of your dog's routine. One other tip is to not make food available throughout the day so that a dog has periods where they can digest the food that was eaten.
