Rescue dog needs heartworm treatment

Rooster was abandoned on the street by his family. He was rescued and taken to the veterinarian by some neighbors. They helped with his medical care but have limited resources, so they surrendered him to my care. A wonderful foster mom has had him for a month after he was released from the veterinarian. He has had antibiotics during this time. He was also neutered. He now requires heartworm treatment. Then 2 more weeks at the foster home to be kept calm and quiet while the heartworms die. After that, i hope he will settle in the yard at a home in Chixculub permanently. He just needs a little more help. Please donate, to get him his treatment.
