Protecting pets from snake bites

One communications point worth emphasizing is that not every snake seen swimming or near water is a cottonmouth; Louisiana has several harmless watersnakes that are frequently misidentified.

Louisiana has several medically important venomous snakes, and most snakebite first aid is about getting the animal to veterinary care quickly rather than attempting treatment at home.

Protecting pets from snakebites Keep dogs on a leash when walking in wooded areas, near waterways, on trails or in areas with tall grass or heavy vegetation.

Don’t allow pets to investigate holes, brush piles, fallen logs, dense vegetation or areas beneath buildings.

Mow tall grass, trim overgrown vegetation and remove piles of lumber, leaves, debris and other places where snakes may shelter.

Keep pet food, birdseed and garbage securely stored, and address areas where rodents may live.

Be especially cautious around water.

Cottonmouths and several harmless watersnake species occur around Louisiana's ponds, lakes, bayous and wetlands.

Use extra caution when visibility is poor.

Carry a flashlight when walking pets outside at night.

The report adds to ongoing university-led research relevant to veterinary medicine, animal health, and clinical decision-making.
