I don't know if this is something all dogs do, or just mine.. But I have a larger dog (She's a mutt) who is trained to do her "business" outside. If we're gone all day and she doesn't get to go outside at her regular time, she'll throw up rather than go potty inside the house...Which is not all that great. I'd rather clean up poop than puke, but I guess it shows we did a pretty good job house training her.
