Approximately 150,000 dogs and cats in the United States are bitten by venomous snakes each year. It's unknown how many nonvenomous snake bites occur, as these bites rarely show up at veterinary clinics. Statistics show that approximately 80% of dogs survive venomous snake bites with prompt care. Any breed of dog is susceptible to the effects of rattlesnake venom. Some dogs, however, are more likely to have a high drive to attack these animals. Dogs with high prey drives and rural or hunting lifestyles are more likely to find themselves in harm's way when it comes to rattlesnake envenomation.

What does a snake bite in a dog look like?

Swelling will be significant and spread quickly. The bite wound will tend to bleed, or there will be bloody discharge. You may not see puncture wounds due to the rapid swelling or the smaller fangs of some snakes.

What to do if my dog killed a snake?

It's essential you get your dog to your local vet immediately or as soon as possible. Call them and tell them you are on the way so they can prepare, as your dog is likely to need anti venom for their best chance of survival. Without treatment, prognosis for snake envenomation is extremely poor.

Arizona is home to no less than 13 species of rattlesnakes, more than any other state,as well as other snakes that are non-venomous. 

The Mohave rattlesnake is the most toxic of the species, but the Western diamond-backed rattlesnake is responsible for more bites and deaths, than any other type of rattlesnake.

A question we often hear is can a dog survive a snake bite without treatment?

Unfortunately, the answer is almost always no. But how quickly they receive treatment is key to their recovery. There are a number of factors which contribute to how quickly symptoms present and how long until the bite becomes fatal.         

Can dogs survive snake bites?

Statistics show that approximately 80% of dogs survive venomous snake bites with prompt care. Factors that influence survival include the size of the dog, the duration of time between the bite and receiving emergency treatment, as well as the location of the bite. 

Preventing Snake Bites

Here are some proactive steps owners can take to avoid snake encounters:

• Keep your dog on a leash when walking or hiking in areas with high snake populations.
• Avoid rocky areas and tall grass, which can serve as hiding spots for snakes.
• Be aware that snakes are more active in warmer months, increasing the risk to pets.
• Maintain a snake-proof yard by keeping grass trimmed, reducing hiding places like wood piles, and controlling rodent populations.
• Complete k9 snake avoidance training.

As summer peaks, stay vigilant for snakes in the grass—giving them space can help protect your pet from a painful bite and an emergency vet visit!

Most pets have a good prognosis for venomous snake bites when treated quickly. Delays in treatment can increase mortality rates.

Since the amount of venom injected is uncertain, all bites are treated as if some venom has entered the victim. Hospitalization for at least eight hours is typically recommended for monitoring and supportive care. Smaller pets may face greater risks of complications.

Key treatments include:

• Antivenin: Specific to each snake type (except coral snakes). Many pets recover without it, but it can be expensive and may cause allergic reactions.
• Pain Medications: Narcotics are often used to manage pain, while nonsteroidal anti-inflammatories should be avoided due to potential bleeding issues.
• Intravenous Fluids: Many pets require IV fluids for supportive care.

Other treatments like steroids, antihistamines, and antibiotics generally show limited benefit but may be needed for pets in shock or experiencing anaphylaxis from antivenin.
