Many dog owners report seeing their pets munch on grass only to vomit shortly afterward. This combination of symptoms can point to several underlying causes. We outline why dogs eat grass, what it means when they vomit afterward, and when to seek veterinary help.
Some dogs eat grass when their stomach is unsettled because the irritation triggers vomiting and provides relief. Others do it out of boredom, habit, or mild anxiety.
This situation poses a chicken or egg dilemma: Does a dog eat grass to relieve their aching stomach, or does it cause them to develop a stomachache and vomit? In fact, statistics show that only 10% of dogs show signs of illness before eating grass, and fewer than 25% vomit after eating grass.
Grass eating is common in dogs of all breeds and ages, and researchers haven't pinpointed a single explanation. What we do know: fewer than 25% of dogs vomit after eating grass, which means the vast majority are happily grazing without any digestive drama.
ctually, grass eating and vomiting tend to go hand in hand. For some dogs, theyll eat grass and bring it back up soon after. Many experts believe that this carries advantages. It can help dogs bring back up toxic substances they recently ate, or parasites residing in their stomach.
