My Dog is Eating Grass (Weeds): Is it safe?

Why does my dog eat grass all of a sudden? This is a nightmare question most pet owners keep asking. You must have seen your dog grazing on your lawn and asked yourself many question. Is he unwell? Is he hungry? Is it safe? There is no specific reason why dogs eat grass. Dogs will still feed on weeds even when they have just eaten their favorite meal. Surprisingly, they sometimes gag or vomit the grass before going ahead to eat more.  

Various reports are trying to unearth this mystery but none of them has been approved as truth. There is an idea that a dog eats grass to throw up especially when having a stomach upset. It points out that, eating grass causes throat irritation and hence a remedy for the stomach problem such as gassy. This has been disputed since most canines that feed on grass does not end up vomiting. In fact most dogs that chew grass have not been reported to be unwell before and after.

While dogs on a balanced veterinarian approved diet will still shock you with this behavior, the idea that it is a way of compensating for a missing nutrition element in the body does not hold water. Although some weeds or grass may contain some nutrients or fiber suitable for digestion but it is not yet stated as the main reason.  

Improving digestion or dealing with agitation by intestinal worms is also another unverifiable reason. Reports have suggested that dogs are not intelligent enough to know the right medication for their ailments and therefore that cannot be true.

In fact, most veterinarians consider it a normal dog behavior.”

Dogs could be eating grass simply because they like how it taste and the texture. The same way human being would find a strange weed to be tasty and good for eating.
