Grass eating dogs

[KAREN]

Is it true that when dogs eat grass it means they have a stomach upset?

[Jillag]

Yes they do it to make themselves sick to clear there stomach

There are different theories as to why they do this, one is that they like it, another is that they do it when they have a stomach complaint and yet a third is that they need the vitamins and trace elements that they don't get from meat. Try looking at PetEducation.com.
