Frequently asked questions

Florida vet costs vary widely by metro — Miami and Fort Lauderdale tend to run higher than Tallahassee or rural Florida. Prices have risen sharply across the state in 2024-2026.
Where can I find lower-cost a heartworm test in Florida?
Look at: nonprofit veterinary clinics in your Florida metro, veterinary teaching hospitals (University of Florida in FL, Cornell in NY, Virginia-Maryland Vet School in VA), and dedicated low-cost surgical clinics. Quality varies — read reviews and verify the clinic uses modern anesthesia protocols and pain management.
Why does my dog need an annual heartworm test?
Federal labeling and best veterinary practice require it. Giving heartworm preventive to a heartworm-positive dog can trigger a severe reaction — the annual test rules that out.
Can RexVet prescribe heartworm preventive?
Yes — with a current negative heartworm test on file. RexVet can prescribe Heartgard, Simparica TRIO, NexGard PLUS, and similar through RexVetRx for monthly delivery.
Does my cat need a heartworm test?
Cats are unusual hosts for heartworm and tests are interpreted differently. Most cats don't need annual testing unless they show symptoms — but cats in heartworm-endemic states should be on monthly preventive.
What if my dog tests positive?
Positive results require additional testing to confirm, then a multi-month treatment protocol. Treatment costs typically run $1,000-3,000+ depending on severity. Prevention is dramatically cheaper than treatment.
