You ’re enjoy a peaceful dawn in the backyard when dead your dog starts munching on grass like it ’s a epicurean salad . If you ’ve ever wondered , “ Why on world is my dog eat eatage ? ” you ’re not alone . This peculiar behavior bedevil many favorite parent and sparks concerns about whether it indicate a health trouble or nutritional deficiency .
As a veterinarian with over 15 year of experience in companion animal medication , I can assure you that grass - feeding is one of the most common canine tooth behaviors I talk about with worried pet owner . The good news ? In most type , this behavior is completely normal . But understanding the science behind why dog run through Mary Jane can help oneself you determine when it ’s harmless and when it might warrant a closer look .
The Evolutionary Origins of Grass-Eating
To understand why your domesticated companion chew on your lawn , we need to look back at their wild ancestors . Dogs evolved from wildcat , who are primarily carnivores but occasionally ware industrial plant material . subject area of wolf scat have reveal that wild canids do ingest vegetation , admit grass , in small amounts .
This evolutionary history has leave our domesticated heel with certain instinctual behaviors . While your pampered pooch may not need to hunt for their dinner , many primitive behaviors persist hardwired in their desoxyribonucleic acid – and pasturage - eating seem to be one of them .
Common Reasons Dogs Eat Grass
enquiry in veterinary skill has identify several possible explanation for dope - eat conduct . Here are the most well - supported possibility :
1. Natural Scavenging Behavior
Dogs are facultative carnivores , which means they primarily eat nub but can hold up on plant matter when necessary . Unlike obligate carnivores ( like cats ) , dogs have evolved some ability to endure and excerpt food from plant materials .
Dr. Benjamin Hart , a distinguished professor at the UC Davis School of Veterinary Medicine , conducted one of the most comprehensive study on grass - feeding in dogs . His inquiry suggests that this behavior is a normal scavenging inclination inherit from wild canid ascendent who would from time to time down entire prey fauna – tummy contents and all – which often contained plant life cloth .
2. Dietary Fiber Supplementation
One common theory is that dogs eat pot to increase fibre in their dieting . flora material provides fibre that can aid regulate digestion , and some veterinary nutritionists believe frankfurter may instinctively seek out grass when they demand extra fiber .
character aids in right intestinal function by :
If your domestic dog seems particularly eager to rust locoweed after switching foods or when have meek digestive upset , they might be seek additional fibre to assist their system run smoothly .
3. Self-Induced Vomiting
Perhaps the most widely discourse theory – and one that has gained significant scientific support – is that dogs sometimes rust grass to induce regurgitation when they feel nauseous or have tummy discomfort .
In Dr. Hart ’s subject , only about 25 % of dogs routinely puke after eating pasture , paint a picture this is n’t the primary motivation for all eatage - eat dog . However , for some canines , particularly those who quickly ingest big amounts of grass without much chewing , it does appear to serve as a lifelike emetic ( vomiting persuader ) .
The long , unchewed blades can tickle the throat and tum facing , spark off the vomiting reflex . Some experts believe this represents a mannikin of self - medication – when dogs feel unwell , they may instinctively feed forage to purge whatever is causing their discomfort .
4. Psychological Factors
For some dogs , grass - eating may have psychological components :
Boredom relief : Dogs with insufficient genial and physical stimulant may eat forage merely as something to do . This conduct is more coarse in young dogs and high-pitched - energy breeds who need regular usage and enrichment .

Puppies and untried dog often explore their environment through their mouths . Grass - eating may begin as childlike oddity about a unexampled taste or texture and originate into a habit over time . Young dogs are by nature more observational with what they put in their mouths .
The Science of Taste: Why Dogs Choose Grass
Interestingly , dogs appear to be somewhat selective about the grass they wipe out . Research indicates they may prefer younger , more tender shoots that contain gamey moisture subject matter and potentially more digestible nutrients .
Dogs have fewer taste receptor than human – about 1,700 equate to our 9,000 – but they can still distinguish between different flavors . Their taste buds are particularly attuned to detect :
The slenderly sweet flavor of new spring grass may be in particular appealing to dogs , which explains why many pet owners notice increased skunk consumption during spring and other summer when fresh outgrowth is abundant .
When Grass-Eating May Indicate Health Issues
While skunk - feeding is usually normal behavior , sure patterns might suggest an underlying problem :

Some detent with psychological return acquire fixations on wipe out non - food items ( a condition called pica ) , and grass can become a target area of this compulsive behavior .

For most domestic dog , periodic locoweed consumption poses minimum health risk . However , there are several of import safety considerations :
