NORTH PLATTE, Neb. (AP) – Veterinarians around North Platte in central Nebraska are reporting a rise in the number of dogs they’re treating for rattlesnake bites. The North Platte Telegraph reports that it’s a problem local vets see every autumn. Craig Kelly, a vet at Westfield Small Animal Clinic, says his clinic treats three to four cases a year. Kelly says the increase isn’t because of more active snakes, but more likely hunting dogs invading rattlesnake habitats as fall hunting seasons get under way. The treatment is not cheap. Susan Sjeklocha, veterinarian at Sjeklocha Veterinary Clinic, says the antivenom can cost anywhere from $600 to $4,000 per dose.
