Eric, a three-year-old Chihuahua, underwent 17 rounds of weekly chemotherapy, plus four months of veterinary care before the San Diego Humane Society deemed the rescue pup healthy enough for adoption. Shortly after being declared ready for a forever home, Eric found his family, Fox 5 reports. Before his adoption, the San Diego Humane Society celebrated Eric's cancer-free diagnosis with a special party. At Eric's celebration, he was honored with his very own cake and posed for photos with the team that helped care for him. Animal Rescue Volunteer Fulfills Mission to Get Dog Stuck in Shelter Since 2016 Adopted Eric is healthy and happy now, but the lucky dog wasn't always in the best shape. He first arrived at the shelter in early July, the organization shared in a press release sent out Nov. 13. When he was first taken in by the San Diego Humane Society, Eric was "covered in ticks and had blood on his feet." After he underwent lab work and full-body X-rays, veterinarians at the Bahde Center for Shelter Medicine determined that Eric had a cancerous tumor. He was also diagnosed with Ehrlichiosis, a tick-borne disease.
