“Our rescue dog has been tested twice since we adopted him to see if his Heartworms have cleared up, but he's still showing antigens; so this way we'll be able to test him more often to know when he tests negative before returning to the Vet. It's just a big savings over the standard Vet test & a comfort to us to be able to test more often. I purchased from this company years ago for different issues with other dogs & it was also a big savings & yielded excellent results. I love this company & appreciate that they help people on a budget take good care of their pets!”
