Dry heaves is hard gagging or attempting to vomit without a discharge. It is an indication of a potentially serious condition that requires veterinary attention. Dry heaves may indicate that your pet has internal parasites, internal infection, food allergy, bloat, liver dysfunction, or has swallowed and ingested a poisonous substance, such as bone meal fertilizer, which is very attractive to dogs who see it as a food source. In other cases, dry heaves might be caused by a head injury or bloat, a potentially life-threatening condition that can lead to shock and ultimately death.
