The reasons why dogs have not pooped for several days:

1. Constipation caused by improper diet. The food we eat daily is too dry and rough, the body lacks water, and the dietary fiber intake is too little.

2. Dogs often eat irregularly and their gastrointestinal digestion is not good, which can easily lead to constipation.

3. Lack of exercise, which is more common in obese dogs, requires dogs to maintain an appropriate amount of exercise every day.

Methods to prevent constipation in dogs:

1. Diet adjustment. Pay attention to a light diet and give your dog more fruits and vegetables to supplement vitamins and fiber. And guide the dog to drink more water to moisturize the intestines, help soften the feces and reduce the situation of poor defecation.

2. Gastrointestinal care. Pay attention to regular feeding and reduce difficult-to-digest foods. You can feed some Wangsu Tong to supplement beneficial bacteria and increase intestinal peristalsis.

3. Exercise appropriately. Taking your dog out for more activities. Proper exercise can also increase gastrointestinal motility, help digestion and prevent constipation.

4. Seek medical examination. If the above measures fail to make the dog defecate smoothly, go to the hospital to see if there are broken bones, toy parts and other foreign objects in the intestines that are blocking the intestines, making the dog unable to poop.
