Heartworm Prevention: Why Bay County Dogs Need Year-Round Protection
Local veterinarians explain why consistent prevention is essential in Florida's warm climate

Bay County's warm climate and year-round mosquito activity make heartworm disease a serious threat to local dogs. This preventable condition affects hundreds of dogs in our area each year, yet many pet owners don't realize the importance of consistent prevention.
Heartworm disease is transmitted through mosquito bites. When an infected mosquito bites a dog, it deposits tiny heartworm larvae into the bloodstream. Over six to seven months, these larvae mature into foot-long worms that live in the heart, lungs, and blood vessels, causing severe damage to vital organs.
Florida ranks among the highest states for heartworm prevalence due to our subtropical climate. Bay County veterinarians report seeing cases throughout the year, with peak transmission occurring during warmer months when mosquito populations surge.
Many dog owners mistakenly believe they can stop prevention during cooler months. However, Panama City's mild winters mean mosquitoes remain active year-round. A single missed dose can leave your dog vulnerable during a critical window.
Contact your local veterinarian to discuss heartworm prevention options and schedule a test for your dog. The small investment in prevention today can save thousands in treatment costs and protect your dog from a potentially fatal disease.
