What Are the Symptoms of Dog Flu?

Symptoms Are Similar to
Other Canine Respiratory Infections

Without proper diagnosis, all canine respiratory diseases look similar. Dog Flu is a viral disease and therefore is more difficult to treat than canine (kennel) cough, which is a bacterial infection easily treated with antibiotics. The best way to protect the dog you love is to vaccinate against both viruses.

Contact the veterinarian if your dog is showing
any of these common signs of Dog Flu.

Did You Know?

The symptoms of Dog Flu, a virus, are almost identical to those of canine (kennel) cough, a disease
caused by the Bordetella bacteria. However, while Bordetella-related illnesses can be treated with
antibiotics, there is currently no treatment for Dog Flu. Dog Flu is a potentially more severe viral
disease and can only be addressed with supportive treatment. The best prevention is vaccination.

It’s important to vaccinate for BOTH Bordetella and Dog Flu, especially if your dog
is social. Many daycares, groomers, and boarding facilities are already requiring
both vaccines, and it can mean the difference between life and death.
