So your dog is eating grass. This is quite common and you needn't get all worked up about it. There are a few reasons that your beloved furry friend is indulging in the greens.
The primary reason that your pooch is indulging in the green blades typically found in his backyard is because it tastes good. Yep, it's that simple, It tastes good to them. If you observe more closely you will likely find that there are specific blades of grass that are pooches favorite. She'll forage for the same type of young bright green grass. The darker, thicker and older blades are normally passed over. One reason we think 'furry' chooses the young blades is because they are sweeter and more tender hence more tasty. Another reason is that the young blades offer ample amounts of Chlorophyll. We all benefit from daily greens.
There is another reason you may see your pooch snarfing down gobs of green grass without regard. This behavior indicates stomach upset. She may have ingested something that needs to get back out. Maybe bad food, random environmental intakes, etc. This type of grass intake will more often than not produce vomiting. Which likely was the reason for her eating gobs of grass in the first place.
Dogs are amazing creatures and we can learn from watching them and their behaviors.
