Causes of dog constipation

There are many reasons why your dog is constipated, and probably the number one reason is that he’s eating things that are indigestible, which will automatically become lodged in the colon, preventing his feces from advancing.

There might be other reasons for constipation, such as:

Diet

• items that are hard to digest;
• diet change;
• low-fiber diet.

Change in household and routine

• stress from boarding, traveling, or even dealing with the presence of a new person in the home;
• getting less exercise.

Grooming

Pain that hinders pooping

• tumors of the rectum.
