Canine Flu

Have you heard about the canine flu outbreak that is currently spreading through the US? Fido’s flu is very contagious, causing sickness in about 80 percent of exposed pooches. The most recent outbreak has been going on since 2022. A local Frisco, TX vet offers some insight on the dog flu below.


There are several strains of dog flu, which is an influenza A virus. The most common ones are H3N8 and H3N2, both of which are highly contagious. The virus can be spread through respiratory drops, and unfortunately remains active outside Fido’s body for several hours. That means your pooch can get infected by sniffing a branch an infected pup played with earlier that day, or simply by nose-booping his four-legged buddies at the park. Shared toys and dishes are also common sources of contagion. As one may imagine, dog parks, daycares, grooming salons, and kennels tend to be hotspots. You can monitor the current outbreak at the website here.

Warning Signs

The signs of dog flu are pretty similar to the signs of human flu. These include coughing, nasal discharge, fever, lethargy, and reduced appetite. Coughing is most likely the one you’ll notice first. However, every dog reacts differently to flu viruses. Some dogs have no noticeable symptoms at all, and may just seem extra sleepy for a few days. Others may present symptoms, but recover within a few days. There’s also a small percentage of pups that get very, very sick. Canine flu can be fatal, though fortunately this is rare. Ask your vet for more information.


There is no cure for the flu: treatment basically consists of keeping your canine pal hydrated and comfortable. Most dogs will recover on their own. However, in severe cases, veterinary care may be necessary. Your vet will be able to offer specific care tips. However, don’t bring Fido to the clinic without letting them know in advance. You don’t want your furry friend getting other pups sick! Your pooch will be contagious for about a month, so keep him away from his pals until your vet gives you a thumbs-up. Of course, your best option is to protect your beloved pet by getting him vaccinated. Ask your vet for details.
