I am rescuing a Collie-Golden mix from a local shelter. He is heartworm positive and the shelter is so poor they cannot afford the treatment that kills adult heartworms. If I don't adopt him, he would be euthanized. I also do not have the money for the treatment, but if every one of my friends gives a little then I know we can knock them out. Aden is being put on Doxycycline and Ivermectin to prevent the growth and spread of the worms, but they can still cause damage to his heart if the adults are not killed. Please give what you can and I'm saving up to. My vet says it should take two to three months anyway before we start the treatment which kills the adult heartworms.
