Gastric phytobezoars as a cause of vomiting in dogs
Dogs eat grass…obviously. Most of the time it seems to go through OK. or sometimes it gets vomited back up. Grass in the gut is an everyday sonographic finding in canine patients and can sometimes present a diagnostic challenge. However, in the vast majority of cases, once identified, it’s usually a fair assumption that it’s an incidental finding rather than the cause of gastrointestinal signs. Usually.
And yet, in 30 years or so I’ve now seen about 10 dogs whose vomiting persisted until gastric ‘grass ball’ phytobezoars were removed surgically or per endoscope and then resolved. As far as I’m aware this is not well-documented in the literature (although to be fair most vets aren’t surprised that it happens).
So, it’s important to be aware that most grass in the stomach is incidental….but there’s always a possibility that it might be a problem in itself if there’s an accumulation. Sonographically, I’ve found gastric phytobezoars challenging.
