How to Treat Snake Bites in Pets

Call your Veterinarian ASAP

The earlier antivenom is administered, the better the chance at reducing or preventing life-threatening symptoms and serious illness. Generally, there is a 6-hour window from the time of the bite where antivenom gives the best results. Though it’s possible to give antivenom after 6-8 hours and still get some effect.

EPCT is open 24/7 for this reason!

There is NO at home treatment that is safe or effective for envenomation, and common prescription or over-the-counter anti-inflammatory/pain management treatments can even be detrimental - all pets with snakebites should be evaluated by a veterinarian so that appropriate and safe treatments can be implemented. If left untreated there can be serious complications including fatality.

Do not try and suck the venom out! This is ineffective and can be very harmful to you.

Do not apply tourniquets. Tourniquets applied to limbs have not been shown to reduce systemic toxicity from the venom and have actually been shown to result in more localized tissue damage in limbs that have been bitten.

Be aware of the signs of snake bites and act quickly if an encounter occurs. Your vigilance can save your pet’s life.
