Causes of dog constipation:

1. Dog food is too dry. Dog food that is too dry and lacks moisture can easily cause constipation in dogs.

2. Nutritional imbalance. Imbalanced nutrition and eating too complex foods that lack fiber can also cause constipation in dogs.

3. Sudden change of environment. Dogs are very sensitive to the environment. If they are suddenly given a new environment, it will cause the dog to become uneasy and affect their eating and defecation.

4. Obesity. Obesity can also cause constipation in dogs, so you should pay attention to the amount of exercise your dog gets.

5. Intestinal blockage. Ingesting irritating or indigestible substances, such as eating some chicken bones, duck bones, or accidentally swallowing cloth, stones and other foreign objects. The intestines and stomach cannot digest these foreign objects, which will naturally cause gastrointestinal blockage and constipation. Can't pull it out.
