You might get confused when you see your dog eating grass, and then vomits it all up. Dogs don’t have the enzymes to break down fibers. Still, this is a very common behavior among dogs. No one knows for sure why this happens and there are many explanations.
The most common reasons are:
Sometimes they enjoy it
Dogs are naturally programmed to obtain nutrition anywhere they can find it. This behavior may stop if you change to a high-fiber dog food. It’s wise to ask your veterinarian before making sudden changes to your dog’s diet.
Due to gastrointestinal upset
Some specialists believe that dogs eat it due to stomach distress, and he turns to grass as a form of self-medication. However, this is quite uncommon, and only 10% of them showed signs of illness beforehand.
Some dogs might eat grass to treat intestinal worms like roundworms, whipworms and heartworms.
To fulfill a nutritional requirement
Another theory says that it’s due to extreme hunger or if their nutrition is weak. Consider asking a professional to see if your dog’s diet is adequate.
It is believed that this grass eating behavior was inherited from their ancestors. To survive, they would have great hunting skills to survive. Eating grass may have helped to conceal their scent from their prey.
