Protect your pooch. There’s a highly contagious strain of dog flu going around, according to KXAN.

The news station reports that veterinarians are warning dog owners about H3N2, a highly contagious strain of canine influenza spreading through Central Texas. Almost all dogs exposed to the virus will contract it, and 80 percent will show symptoms, Dr. Taia Lubitz told KXAN.

Vaccinations don’t completely protect dogs from H3N2, though the virus is rarely deadly. From KXAN:

“Symptoms of H3N2 are coughing, nasal discharge, decreased appetite, decreased energy and fever in the more extreme cases. Dr. Lubitz says the dogs most vulnerable are ones that are constantly around other dogs. Avoiding places like dog parks, kennels, boarding facilities, grooming facilities, will decrease the chances of your dog getting sick.”

This isn’t the first outbreak of the flu. It also made headlines in 2016. Find out more about the virus and what you can do to prevent it.
