Even though Halo has never missed a dose of preventative, he still tested positive for heartworms. We had to go through a few rounds of slow kill treatments but he finally tested negative again! We have mosquitoes almost year round here, so testing for heartworms at least once a year (even with preventative) is super important.
This is a Halo appreciation post because he is as near perfect as a dog can be and he has to live forever.
