Constipation 

Infrequent and/or difficult bowel movements are termed constipation. Dry, hard stool cause pain and straining.
Constipation is a sign of large bowel problems and is not a disease it self. There are many causes for constipation, and often various tests and examinations are necessary to find the underlying cause.
Important Points in Treatment
The usual aim in treating constipation is complete recovery. In some cases, however, therapy is designed to control the condition rather than cure it, and lifetime therapy is necessary. Your doctor will advise you if anything other than a complete cure is expected.
Treatment of constipation includes diet changes, laxatives, enemas and sometimes surgery.
​Hospitalization may be necessary.
All medication must be given as directed. Please call the doctor if you cannot perform any treatments.
Diet is the most important factor affecting the frequency and character of your pet's bowel movement. Follow the instructions your doctor gives you.
