Our beagle use to eat grass and every time he did, he would vomit.
Sherman likes to eat graze but only the tall grass and only one blade at a time. He never vomits after eating it.
Leroy likes to eat clumps of grass but Leroy thinks he needs to eat something every time that he goes outside.
During winter he eats snow, in the spring and fall he eats mud and in summer he eats clumps of grass.
He’s never vomited after eating the grass, or the mud or the snow.
Years ago it was believed that when dogs ate grass it was a sign that they weren’t feeling well.
But now, that times have changed and medical advances have been made the question is:
Why do dogs eat grass?
Do dogs eat grass to make them vomit? or Does eating grass make dogs vomit?
Out of 7 dogs that I’ve had in my life, 3 have been grass eaters and only 1 has vomited from it.
I remember it clearly because I use to clean it up all the time.
So if you asked me I would say it entirely depends on the dog.
I think my beagle ate grass to make himself vomit.
I think Sherman eats it because he likes it.
I think Leroy eats it because he likes to eat clumps of things on the ground. He craves the idea of it but not the actual “grass”
If you ask science:
The UC Davis School of Veterinary Medicine performed a survey in 2007 regarding grass ingestion among dogs and the
correlation between this behavior and illness.
This study revealed that although grass ingestion was common among dogs, no relationship with clinical illness was
However, some dogs were observed vomiting after eating grass.
These dogs, although clinically healthy, did not have access to grass regularly.
Further investigation revealed that dogs without regular access to grass were more likely to vomit after ingesting it.
It is now believed that grass can act as a stomach irritant in dogs that are unaccustomed to it.
It is possible some dogs may learn to associate grass-eating with vomiting and seek it out when they are feeling ill.
However, this study revealed that grass ingestion does not appear to be a form of self-medication in dogs with clinical illness.
In 2008 The University of California had this to say:
So contrary to the common perception that grass-eating is associated with observable signs of illness and vomiting, we found
that grass-eating is a common behavior in normal dogs unrelated to illness and that dogs do not regularly vomit afterward.
Vomiting seems to be incidental to, rather than caused by, plant-eating.
Should you let your dog eat grass?
While most veterinarians seem to think that eating grass isn’t harmful to your pet you should make sure that the grass they are eating is free of chemicals.
We don’t treat our grass so I have no problem with the boys grazing on it but while we don’t use chemicals my neighbor does.
I always pay attention to when she has her yard treated and will keep the boys away from that side of the yard.
If you suspect that your dog is eating grass because they don’t feel good it’s recommended that you speak to your veterinarian.
So is your dog a grass eater? A grazer? Do they ever vomit?
