Hi. I am Barb, and I had Bennie, a Greyhound who died, but not of Blasto.. We really probably licked that one.. But he had congestive heart failure.... He was on Itraconazole, and it was clearly beating the Blasto. which we found in a biospy, confirmed.... Anyway, since the blood work is normal, the Itra might be just fine, but do keep an eye out for signs of heart failure as the Itra can cause that....... It's a "black box" warning item. Sorry to give you that sort of ugly information, but the more you know, the better chance your adorable girl has.
SO. The coughing.. Gagging is what most people say it is like. That was how Bennie coughed, gagging.... His Blasto wasn't found in his lungs, it was in a rib, so we had thought it was osteosarcoma. This Blasto is is very difficult because it likes to mascarade as other diseases. It hides, too, and when the itra starts to work, it fights back and shows up in other places. I wish more people were checking in because there is so much experience for you with all of this, but if you read posts by Cosmo, and Wilson3 and apope and bulldogger, and Lovemyquincy, to name a few, you will get a ton of good experiential information. Good luck to you. I love Bassetts, and hope the best for your dog. We do know that you should not give Heart guard to a dog taking Itra, just so you know that... and I would ask your vet to look into the black box warnings about Itra, because the heartworm complication has my attention....
