A month after Tucson’s — and once the world’s — largest dog has scampered off to that great dog park in the sky, the community is paying tribute to him with a day of service.

Giant George Service Day is Sunday.

George, a Tucson Great Dane who was once crowned the Guinness World Records World’s Tallest Dog, died at age 7 Oct. 17, a month before his eighth birthday.

George, who measured 43 inches from foot to shoulder, reigned as the record holder from February 2010 to September 2012, when he was overtaken by Zeus, a 44-inch-tall Great Dane from Otsego, Mich.

George was featured in a book co-written by his owner, real estate agent Dave Nasser, and appeared on national talk shows. His Facebook page drew more than 211,000 likes.

George’s handlers and fans are encouraging others to volunteer and donate to animal-related causes. Pima County Supervisor Ray Carroll will commemorate the event from 1 to 3 p.m. Sunday at Bookmans Sports Exchange at the Rancho Center, 3330 E. Speedway.

There will be raffles of the book, “pawtographed” by George, every 15 minutes during the event.

Several pet-helping agencies will appear at the event, including the Humane Society of Southern Arizona, Pima Animal Care Center, Hermitage Cat Shelter, Azmira, Holistic Animal Care Shoppes, A Loyal Companion, Canine Massage and Mobility Services; and Gabriel’s Angels. Eegee’s will provide frozen drinks to the first 500 attendees.

George fans are asked to spend time from 9 a.m. to 1 p.m. Sunday volunteering for animal-related charities.
