Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
Hi there and thank you for your question. My name is ***** ***** I am a licensed, internship-trained veterinarian with 11 years experience in general medicine and emergency and critical care medicine and I would be happy to assist you. Please be patient as there may be slight delays in responses as I research your pet's issue.
Have you had him since he was a puppy? What heartworm preventative is he on, and where did you purchase from- online, or from your vet?
Okay. How long has he been on Heartgard?
Okay. So, basically, the dog got heartworm disease while on ProHeart, then. If you are can prove at your vet clinic that your dog got the injection every 6 months without even being a day late, then the company who makes ProHeart will pay for heartworm treatment. It is possible to get Heartworm disease while on ANY kind of heartworm preventative because they are all over 99% effective, NOT 100% effective. It appears your dog was in the unfortunate less that 1% where it is not effective. That stinks! Since it has been less than a year that your dog has had it, there is not likely to be any permanent damage, and I would start treatment right away. But I would contact Proheart through your veterinarian once you have obtained the documentation showing that you were never even a day late on the 6-month injections. (If you were ever longer than 6 months between injections, then that is how the dog got heartworms... but I suspect it is more likely to be a failure of the product). I am so sorry you are dealing with this! I hope Bandit starts treatment soon and that you can get the company to pay for the treatment, which should not be difficult.

By the way... with two antigen tests, he definitely has heartworm disease... there's no other explanation. Best of luck.
