There are four venomous snakes in Central Texas, according to Texas Parks and Wildlife. Three of these snakes are known as pit vipers- Copperheads, Cottonmouths (also known as Water Moccasins), and Rattlesnakes. The fourth venomous snake that lives in Central Texas is the Coral snake. Known for its order of colors of bright red, yellow and black stripes these snakes are commonly mistaken for milk snakes. This happens because they share the same colors, but the milk snake has red touching black instead of red touching yellow, and they are not venomous.

How to Avoid Snakebites

Dogs are naturally curious animals and are not afraid of snakes. Learning where snakes live is important to know how to keep your dogs from coming into contact with them. Snakes tend to live in tall grass, woodpiles, bushes and underneath outdoor debris to avoid sunlight. Snakes will bite when they feel threatened. The cottonmouth lives in tall grass in and near the water edge. When going outdoors, it's advised to keep your dog on a leash and to avoid these areas. Yard maintenance is also necessary to keep away an attractive nesting ground for snakes near your home. When walking your dog, stay on well-kept trails and avoid walks at night unless in a well-lit area. Don't let your dogs stray from your sight.

Snake avoidance training is helpful for owners and dogs who live on large properties, take off-leash hikes and spend lots of time outdoors. Snake training can help anyone with a dog who wants to prevent future snakebites. (Seek advice from your veterinarian on what trainers might do this locally.)

There is a rattlesnake vaccine, but there have been no controlled studies for its effectiveness. That said, the vaccine may create protective antibodies that might be useful in neutralizing some of the injected venom. It’s important to mention that even if the dog has been vaccinated, he will still need to be examined by a veterinarian to determine just how much treatment will be necessary. Please talk to your veterinarian about whether or not this vaccine is something you should consider for your pet.

How to Tell if Your Pet has been Bitten and What to Do

Snakes bite dogs and cats most commonly around their mouth, ankles and legs. Snakebites are small and hard to identify, but the wound will begin to quickly swell, bruise and bleed a little. There will be significant pain, but the amount of venom released will determine the signs of the bite. Most pets will display similar signs when bitten by a venomous snake. Coral snake bites are different than pit vipers because they cause nervous system failure which can manifest as tremors or even seizures. When bitten on the mouth or the head it can cause trouble with your pets breathing. Some pets can go into cardiovascular shock which raises their heart rate and can potentially cause your pet to go unconscious, as well as vomiting and diarrhea. After these signs, the area the snake has bitten can turn black and die from the venom, which can cause other serious complications.

All snakebites should be taken seriously and as an emergency. Taking your pet to see a veterinarian immediately is critical. If it can be done safely, immobilize the part of the animal that has been bitten by the snake. Try to keep it at or below the level of the heart. Keep your pet calm and immobile; carry if necessary. Seek veterinary attention as soon as possible. Try to identify the snake if it can be done without risk: Do not attempt to capture or kill the snake. It is helpful to identify the type of snake to aid your veterinarian with treatment. Do not bring the snake into the veterinarian’s office – a photograph will do.

It is NOT recommended to use a tourniquet or ice pack, to attempt to remove the venom, or to administer medication to your pet unless directed to do so by a veterinarian.

Treatment for Snakebites

The first goal in snakebite treatment is to keep the venom from circulating in large quantity throughout the body. However, keeping all the venom in the area of a bite (as happens with ice packs or tourniquets) may cause severe muscle damage. Antivenin administered at the hospital is the most direct and helpful treatment for your pet. Ideally, Antivenin is administered within two hours of the bite to be the most effective. Antivenin can cause severe allergic reactions in some pets, and must be administered under controlled conditions and monitored closely. Most pets that have been bitten will need to be admitted to the hospital for treatment, and some pets can have large areas of dead tissue that need to be surgically cleaned over several days or weeks.

Once arriving to the clinic your pet will receive pain medication,  IV fluids, and the area where the pet was bitten will most likely be shaved. Some diagnostics should be performed (including bloodwork). Plasma may also be helpful in cases where there is severe vasculitis (inflammation of the blood vessels). Once the venom is in the bloodstream, it can destroy a patient’s blood cells. Antivenin works to neutralize the effects of the venom and in some cases more than one dose of antivenom might be necessary.
