Titan, a 4-year-old white Great Dane from San Diego, is blind, deaf, epileptic and requires chiropractic adjustments every three weeks.

He’s also now officially the world’s tallest dog.

Titan’s designation was announced yesterday— the official Guinness World Record Day, the Associated Press reported.

“Titan is magical,” owner Diana Taylor said. “He’s low-key, calm and has a wonderful demeanor about him. He gets along with all dogs, even the tiny ones.”

Titan, as measured by a veterinarian, is a over 3½ feet tall from floor to shoulder. Add in his head, and he’s over 4 feet tall.

Standing on his hind legs — which is something Titan doesn’t do — he would be nearly 7 feet tall.

Titan weighs 190 pounds.

Titan takes the title held by Gibson, a 7-year-old harlequin Great Dane from Grass Valley, who died earlier this year after battling bone cancer.

Taylor was living in Atlanta when she adopted Titan as a puppy from the Middle Tennessee Great Dane Rescue. When he could see out of one eye, she taught him sign language. As he went blind, they learned to communicate by touch.
