Unproductive retching reflects a stomach that is distended and often twisted, as happens in GDV. When the stomach twists (volvulus), the normal pathway for vomiting is blocked, so the dog may try to vomit but nothing or only small amounts are expelled. This produces a pattern of repeated retching without producing vomit, which is a hallmark sign of GDV. In contrast, coughing or sneezing are respiratory/upper airway signs and don’t indicate GDV, and vomiting normally would imply actually expelling contents, which isn’t typical in GDV due to the obstruction. If you see unproductive retching, treat as an emergency and seek veterinary care immediately.

Haemorrhage is the escape of blood from the vascular system through damaged vessels. It can be external, evident as visible bleeding, or internal, where blood leaks into tissues or body cavities but the defining feature remains blood moving out of the vessels. An increase in blood pressure isn’t what defines a haemorrhage; it can contribute to vessel rupture, but the event itself is the loss of blood from the vessels. Loss of plasma volume describes a reduction in the liquid component of blood and isn’t the same as blood escaping from vessels. The formation of a clot is the body’s response to a bleed, helping to stop haemorrhage, not the definition of the bleeding itself.

Safety is the priority when you reach an injured dog or cat. Make sure you and the animal are safe from hazards, then quickly assess the scene and decide if urgent veterinary help is needed. This order prevents you from getting hurt and allows you to approach calmly and identify what’s wrong so professional care can begin right away. Moving the animal to a quiet room isn’t the first step because handling an injured animal too early can worsen injuries. CPR is a lifesaving action, but it should only be started if the animal isn’t breathing and you’re trained to perform it, otherwise it won’t help and wastes valuable time. Checking for a microchip won’t address the immediate medical needs and isn’t the priority in an acute injury.

Consent from the owner is about respecting their rights and the animal’s welfare by making sure treatment aligns with what the owner agrees to. Before starting first aid, you should explain what you plan to do, why it’s needed, potential risks, and possible outcomes, and only proceed with the owner’s permission. This helps ensure the owner understands options, can make an informed decision, and has chosen a course of action with you. It also protects everyone—the animal, you as the responder, and the clinic—from misunderstandings or disputes about what was done and why, and it sets clear expectations about costs and procedures. If the owner isn’t available in an emergency, you take essential steps to stabilize the animal to prevent suffering, but you should seek consent as soon as possible for further treatment. Rushing to the clinic without consent isn’t appropriate because it bypasses the owner’s rights and can create legal and ethical problems. Insurance claims aren’t the purpose of consent, and consent doesn’t give blanket permission to perform any procedure without liability.
