We live in Fort Lauderdale and were warned by my veterinarian to stay away from dog parks, obedience schools and other areas where multiple dogs are found because there is a really nasty airborne influenza going around that is killing about 5% of the dogs that contract the virus. There is no cure for it. It is highly contagious.
I had this confirmed by 2 other veterinarians, one in Weston and one in Oakland Park. Apparently the influenza originated in a few of the boarding kennels in the area and has spread like wildfire. My vet told me to call him in about a month to see how the spread of the virus was going. If they had no more cases he would give the all clear to go to the parks, etc.
Symptoms include typical flu like symptoms like coughing, gacking, runny nose, fever.
