It seriously irritates me, the way some people chastise their dogs for for eating grass, though it's perfectly normal behaviour (for dogs that is!)
I agree dogs cannot access any enzymes in grass but long tough grass acts as an emetic/stomach irritatant to some dogs so there can be reasons to prevent them eating grass.
It can set up vomiting in some dogs and there can be good reasons for not wanting them to trigger this, such as wanting to rest their stomach during recovery from GI upsets, or if a dog has a sensitive stomach.
Yes it can be a normal behaviour for queasy dogs to attempt to purge themselves (and some dogs happily eat grass without vomiting), and generally they eat a little grass, vomit some bile and happily settle to eat but dogs do not always act in their own best interests! Some dogs who do not vomit back the grass can also have problems passing long stringy grass stalks at the other end.
All about people knowing their own dog and acting accordingly I guess.
