Scavenger hunt

Q: My 18 week old morkie loves eating grass, twigs and flowers. We have to be super vigilant because he's always finding something to put in his mouth (rocks, paper, etc.) walking him is a challenge as he's picking these things up in stride. He recently threw up twice. The first contained only food. 10 min later the second vomit had a piece of clay pot and twig. He's had a bit of water & been resting all night Any remedies or further suggestions on how to proceed??

A: There is no way around this behavior unless you just don't let him out to explore which I feel is not warranted. Fortunately he will solve most indescretion naturally on his own.
