Dog eats grass and vomits

Dr. Marie replied:

Thanks for your question. Some dogs will eat grass if they are feeling nauseous. It seems that they know that grass may help them to vomit and they will likely feel better after they vomit.

However, some dogs just like to eat grass!

If this is something that Tommy has always done I wouldn't be too concerned. But, if this is a new behavior then there are a few possible reasons for him to have intermittent vomiting. It's often hard to determine what the cause is but here are some possibilities:

-Have you changed his food? He may have a food intolerance.
-Is he the type of dog that would eat a toy or foreign object? He may have something sitting in his stomach.
-Have you had him checked for parasites recently?
-Are you near the end of a large bag of food? Sometimes there can be mold on the food that turns it off.

There are also a number of medical conditions that cause intermittent vomiting. I have also found that some dogs need a small dose of famotidine (pepcid) each day to help with this kind of problem, so you can talk to your vet about that.

I hope this information helps!
