Why Do Dogs Eat Their Own Vomit?

• Not a substitute for professional veterinary help.

Tell me if this sounds familiar: you’re sitting comfortably in one room when you hear your dog retching one room over. You try to reach her in time, but just as you walk through the doorway, you realize you’re too late. Not only has your dog vomited, but she’s in the process of eating whatever she just expelled.

Gross, right?
