Dog vomiting for fun?

[Tanya]

We are very frustrated with our dog's vomiting in the house. She isn't sick and she has been doing this for months now. Nothing has changed in her diet; in fact she has eaten the exact same prescription dog food (wet and dry) for 11 years. She loves to eat poop (prefers other dogs', but will eat her own), and we've tried eliminating that with various things on her food, but nothing has worked. And she loves to eat grass--from what we can tell, it's just 'cause she finds it enjoyable, not because she has a sick tummy. And that's what the vet thinks too (nor is she concerned about the poop-eating). She vomits her food, poop, or just grass, but there's not always grass in the vomit. She is probably bored, I will admit that.

The only thing that seems to work to stop her vomiting is us watching her like hawk in the backyard to make sure she doesn't put anything in her mouth, but we have a large yard (1 acre) and she loves it out there, so it's gotten to be where we are just limiting her time outside. Are there any other methods to stop this bad habit she's gotten into, or is this possibly masking something? Our vet isn't concerned if she's otherwise fine.

I don't know about the vomiting, but the poop-eating could be related to a deficiency in her diet. If she is only being given processed dog food, she may be craving the natural bacteria her body needs. I think you could give her some probiotics.
And perhaps by improving her digestive environment, she won't vomit as much either?

My dog has a sensitive tummy, but he also likes to eat anything that's not nailed to the ground. As a result, he'll often vomit the non-food stuff that he ate. One particularly disturbing incident was when he ate (apparently) and enormous amount of dirt out in the back woods, and I woke up in the morning to find this ENORMOUS pile of what I thought was dog poop (runny and very dark), but turned out to be mud.

As he likes to run free in the woods, too, our vet suggested a basket muzzle. It doesn't clamp his mouth shut, but doesn't allow him to eat random crap while he's out of sight, either. This has been a lifesaver also when we leave him alone at home, because he used to chew through everything in his path!
