Beau and Zoe returned from their Moncks Corner, South Carolina, backyard with swollen faces and apparent puncture wounds. When Beau’s swelling increased quickly, Jane Ussery’s family suspected copperhead bites and took both dogs to BluePearl Pet Hospital in Summerville.
His face was huge. And we were like, okay, something happened, Ussery said of Beau’s condition.
Both dogs recovered, but their individual outcome does not predict how another dog will fare. Venomous snake bites can progress rapidly, and veterinary guidance supports immediate assessment rather than waiting for more symptoms.
A cluster of snake-bite emergencies
Dr. Mark McKenzie, an emergency veterinarian at BluePearl, said the hospital treated approximately 12 to 15 dogs for snake bites over two weekends. That total included roughly 10 to 11 cases during the earlier weekend and four during the more recent one.
Ussery said a hospital employee told her that her family was the sixth to arrive that day with suspected snake bites. The family believed copperheads were responsible, but the available information does not establish that every case was independently confirmed as a copperhead bite.
McKenzie said the hospital regularly treats venomous snake bites from April through October. He said encounters with young copperheads increase during spring and early fall, while moisture and changing temperatures can also affect snake activity.
Copperheads occur in South Carolina and favor woodlands or forests with substantial ground cover, according to South Carolina Partners in Amphibian and Reptile Conservation. The organization advises leaving any encountered snake alone and maintaining a safe distance.
Signs warranting urgent attention
Swelling, pain and bruising at a suspected bite site are common warning signs, according to the Colorado State University Veterinary Health System. Bite marks may not always be visible, and some symptoms can take hours to develop.
Facial swelling and puncture wounds can support suspicion of a bite, but they do not establish the cause by themselves. The Merck Veterinary Manual notes that fractures, abscesses, spider envenomation and allergic reactions to insect bites or stings can resemble snake bites.
That uncertainty is one reason McKenzie recommends immediate veterinary evaluation whenever a bite is suspected, even if no one saw a snake. Owners should not delay the trip while trying to capture or closely identify the animal.
Before transport, CSU advises moving the dog away from the snake, keeping the animal as calm as possible and carrying the dog when feasible to limit movement. Owners should not apply ice or a tourniquet, cut the wound or attempt to remove venom by suction.
How veterinarians assess severity
Veterinarians may consider the location of the bite, the dog’s size, the suspected snake, the amount of venom and the time before care began. Examination findings and blood tests can help identify progressive swelling, clotting abnormalities or other systemic effects.
Treatment depends on the dog’s condition and may include intravenous fluids, pain medication, bloodwork and monitoring. McKenzie said antivenom can be expensive but can neutralize venom and improve outcomes when indicated.
Clinical guidance published by Today’s Veterinary Practice says veterinarians may use repeated physical examinations, laboratory findings and a snake-bite severity score to track progression. Rapidly worsening swelling, clotting problems, neuromuscular effects or shock may support a decision to administer antivenom.
Prognosis varies with the snake species, bite location, extent of envenomation, the animal’s size and how quickly treatment begins. Beau and Zoe’s recovery is therefore an individual outcome, not a guarantee for other dogs with similar swelling.
McKenzie advised owners to watch the ground and surrounding area near bushes, woods and wetlands and to keep dogs from putting their noses into bushes. Those precautions cannot eliminate encounters, but they can reduce close investigation of places where a concealed snake may be present.
Ussery said her family had lived in the area for nearly eight years without a similar incident. After Beau and Zoe’s emergency, the family became more attentive to outdoor risks and emphasized having a plan before urgent care is needed.
