Neurologic and hematologic sequalae following a timber rattlesnake (Crotalus horridus) envenomation in a dachshund

Abstract

A 2-year-old female Dachshund had a witnessed timber rattlesnake envenomation. Although rattlesnake envenomations are a common, potentially life-threatening event in companion animals, timber rattlesnake envenomations in the dog are rarely reported. This dog described in this case report had significant hematologic and neurologic clinical derangements consistent with Types A and B rattlesnake venom and a suspected hypersensitivity reaction to the venom. This patient was treated aggressively with antivenom and fully recovered without any persistent neurologic signs at follow-up.
