As an ardent reader of the Collins Dog Photoguide I came across this article, which I feel, might be of interest to readers.

Traffic Accidents
A traffic accident is probably the most common cause of serious injury to a cat or dog. Always approach the animal with caution, it may react aggressively because of the pain.

Move the dog as little as possible, but if you must move it, it is probably best to use a blanket, sliding it underneath the dog. Seek the assistance of another person and lift the dog gently to safety. Check for heartbeat and any haemorrhaging. Attempt to stem excessive bleeding by holding a clean pad or clean handkerchief over the wound, binding it tightly with a makeshift bandage. Call the nearest vet's surgery to warn of your arrival.

Burns
The only recommended first aid is to clean off the offending substance and immerse the body part under cold running water for as long as possible. Seek professional advice immediately.

Heat Stroke
This occurs most commonly when a dog has been left alone on a hot day without ventilation. If your dog has not already collapsed it may be panting, vomiting or frothing at the mouth.

Remove froth and lower the dog's temperature as soon as possible by placing or dousing the animal in cold water. Take the dog to the vet immediately where it will be treated with drugs and more cold water.

Poisoning
Signs of poisoning may include collapse, muscular twitching, vomiting, bleeding or convulsion. Do not hesitate to contact the vet. Take some of the noxious substance to the vet with you if you know what it is. If the dog has recently swallowed the poison, try to make it vomit. Salt and mustard in water will usually work quickly, or a small piece of washing soda (sodium carbonate0 pushed down the throat.

Drowning
It is a popular misconception that all dogs can swim, but this is not always the case. You must attempt to empty the dog's lungs of water as soon as possible. You must attempt to empty the dog's lungs of water as soon as possible. Place the dog's head lower than its body, open its mouth and begin to pump the chest by pressing down on the ribs and releasing the pressure immediately. Repeat at five-second intervals.

Choking
Sometimes a piece of stick, bone or small rubber ball may get stuck in a dog's throat. Your dog may be unable to breath as a result and swift action is necessary.

Open the dog's mouth carefully and see if you can see the object. Pumping the chest, as in the case of drowning (see above) may dislodge the foreign body, get your dog to the vet as soon as possible where the object can be removed under anaesthetic.

Commitment, Firmness, but kindness.
