According to the American Society for the Prevention of Cruelty to Animals (ASPCA), the danger of stray voltage on city streets can turn walking, biking or running your dog into a dangerous and devastating event.

The occurrence seems to be most common in northern climates and urban areas. What happens is stray voltage occurs when dormant utilities leak excess electricity. Add wet streets and salt-based ice melts to the mix, and it’s a recipe for shocking currents of electricity that can, yes, shock, but also injure or even prove fatal for those in its path.

“Since salt used to treat icy streets is a great conductor of electricity,” says Dr. Louise Murray, ASPCA Director of Medicine, “the risk of shock from stray voltage is that much higher during the winter months.”

Here are some tips from the ASPCA to help you avoid potentially hazardous areas, and advice on what to do if your pet has suffered an electrical shock:

• Keep your dog away from metal fixtures, such as lampposts, grates or manhole covers. While these spots may be your pet’s favorite place to relieve himself, they may also conduct hazardous electricity.
• Dog booties may not do much, and if they have any kind of metal adornments, it may make the situation worse.
• If your dog suddenly seems skittish, frightened, angry or upset for no apparent reason, it could be an indication of electric shock.
• If your dog is incapacitated due to shock, don’t try to touch or move him without protective gear, because the shock could pass to you as well. Instead, call your local fire department immediately.
• If you know of an area in your neighborhood that could be affected by stray voltage, contact your city services to let them know.
