Our needs are purely monetary given we fund heartworm treatment for heartworm positive dogs.​Rockwall PAWS pays for the pre-treatment LAB work, Chest X-ray, hospitalization required for the treatment, and the ‘shots’ (Immiticide injections) – the most expensive part of the treatment. Average cost of treatment is as follows: Small dogs between 2-44 pounds cost around $300.00; Medium dogs 45 – 88 pounds $430.00; Large dogs 89-110 pounds may cost over $500.00. There are often other expenses such as Antibiotics, Pain medicine, or Prednisone; if the Veterinarian thinks they are needed.
