Heartworm Treatment

Zara has been diagnosed as Heartworm and Lyme Disease positive.

Heartworm is transferred by mosquitos through larva called microfilaria which grow into adult heartworms that damage the heart, lungs and arteries. It is fatal if left untreated. Unfortunately heartworm is very long and difficult treatment that requires one month of oral antibiotics followed by a series of injections to kill the worms, and a long recovery period while the worms are cleared from the body.

Lyme Disease is a lifelong disease that is treated with the same antibiotics for heartworm treatment. After being treated, Lyme disease does not severely impact a dog's quality of life if treated in the early stages.

Zara's treatment is estimated around $3500, and will last until summer 2022. We need your support to help Zara recover and live her best giant dog life!
