Dog eats grass - vomits frequently - Answered by Dr. Van Lienden

My 10 year old min. poodle, Josie, has been eating grass and vomiting for years, but relatively infrequently (maybe once a month). I have had her checked out at the vet (blood tests, physical exam) with no positive results for any problems. Recently (within the past month or so) she has been doing this at least three times a week. She doesn't act like she feels bad, she will ring to go out and then eat grass, sit down and throw it up (yellow), and come back in and go back to her normal business (sleeping, mostly, but if she throws up first thing in the morning she then eats her breakfast). She has been eating the same food for 1-2 years (NutroMax senior mixed with weight control). She was 3-4 pounds overweight but has lost that since I added the weight control and quit letting her lick dishes. I am concerned that she may be damaging her esophagus. Also, my younger poodle, Annie (1 year old), who learns from Josie, has started copying the grass eating (maybe once every two weeks). Any suggestions?

I think most dogs eat grass when they have an upset stomach,,,my guy eats a certain type of grass only and not all the time...but thank dawg! he usually doesnt throw it up! I usually know because his tummy makes funny noises..

He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.

I wouldn't worry about the grass eating but I would change her food. There have been lots of cases of dogs being fed Nutro that vomit bile several times a week. My previous dogs did this and once I switched their food the vomitting stopped. Many other people reported the same thing. Please check out the Food Forum here for some great information on what to feed your dog.

Chronic vomiting/regurgitation need to be addressed, because, yes, she may be suffering from esophageal/dental damage/metabolic disease if there is a gastric acid component.

Vomiting is different than regurgitation: vomiting is the stomach violently contracting to expel contents, regurgitation is the passive return of esophageal contents--there is no stomach component involved.

Routine blood work may not show any abnormalities, however further testing such as fluoroscopy/endoscopy may reveal the answer.

Alternatively, hypoallergenic/bland low-fat food trial may be of benefit if the situation warrants. There are numerous antiemetic (anti-vomiting) drugs available, but a firm diagnosis before medication makes the most sense.

Please consult your veterinarian for further diagnostics/assessments/treatment plans.

Update to "dog eats grass-vomits frequently"

Thanks for the replies. I started Josie on Royal Canin Special 30 for "sensitive, fussy" dogs. I started mixing it 1/2 and 1/2 with her previous food and after two weeks she's on the Royal Canin straight. No vomiting (self-induced or otherwise) since we started the switch! I wonder if there is something in the food that settles her stomach enough that the Nutro doesn't bother it anymore. I hope that takes care of the problem!
