Bites and stings can be dangerous to your pet due to the venom injected or because your pet is allergic to it. Initial treatment is to apply a special type of bandage - Pressure Immobilization. However most of our pets are bitten on the mouth or around the head and rarely is the bite visible. Pressure immobilization is used for the management of snake bites, spider bites and where allergic reactions are occurring.
SNAKES
The following information is written for Australian Snakes. Different snakes have different venoms and so symptoms of snakebite will be different. However recommended management is the same worldwide.
Many snakes are not aggressive however our pets do tend to be curious about things in the grass and may annoy the snake into attacking. In Melbourne we find most of our snakebites are due to tiger snakes; partly as they are common around the creeks and rivers especially in the Western suburbs and partly because the tiger is a more aggressive snake. We start to see bites in September and the last bite last summer was in April. Snakes are usually more venomous at the start of the season.
PREVENTION
- Clear your yard of all rubbish and long grass. It is also a fire hazard.
- Walk your dog on a lead in areas where you suspect there might be snakes such as along waterways.
- Avoid taking your dog for a walk on warm summer nights in areas you would expect to find snakes as snakes are more active at this time.
- Be noisy when you are walking in the bush.
- Keep sheds free of mice.
SYMPTOMS AND SIGNS
Symptoms can occur rapidly in our pets as they are usually bitten on the face or mouth however sometimes they don't appear for more than 24 hours, especially in cats. Take your pet immediately to a veterinarian if you suspect it has been bitten.
- Drooling, vomiting or diarrhoea.
- Your pet may appear distressed or anxious
- Muscle weakness which progresses to collapse.
- If very lucky the bite wound may be visible. It appears as two tiny puncture marks about 1 cm apart. The area may swell and appear red.
- The pupils may appear wider than normal (tiger snake).
- Your pet may start to may have difficulty breathing.
- There may be "blood" in the urine.
- Some cats will become very floppy like a child's under-stuffed toy and have large pupils, which are unresponsive to light changes. They are conscious and can become very distressed when handled but have no muscle strength to fight.
- Coma
- Respiratory arrest and death.
MANAGEMENT
- Separate pet from snake but do not become a casualty yourself. It is not recommended you try to kill the snake.
- Try to keep your pet as quiet and calm as possible. Do not allow your pet to walk etc unless absolutely necessary. If possible carry your pet to the car and into the veterinary surgery.
- Apply a pressure immobilization bandage if your pet is bitten on a limb. This is not usually the case.
- It may be necessary to give mouth to nose resuscitation in transit.
- Never apply a tourniquet or restrictive bandage.
- Never cut the bitten area or try to suck the venom out of the wound.
- If the snake has been killed take the snake with you. This will allow the veterinarian to identify the snake. If the snake has not been killed then a description of the snake may be of assistance.
- Treating snakebite victims may be very expensive. If you are concerned about the possibility your pet may be bitten at sometime, have a think about what you would do before it occurs. It may be necessary to decide to euthanase or only give supportive treatment and see what happens.
Vitamin C has been used by some people to treat snakebite. This is not a treatment but an aid and will not prevent death if your pet has had a lethal dose of venom.
NON-LETHAL SNAKES
Australia has many non-venomous snakes. Bites from these snakes will not kill your pet however they can become infected. The area around the bite should be clipped and cleaned and watched for signs of infection. If infection occurs see your veterinarian.
