"Danka", a long-haired Chihuahua from Revuca, Slovakia, weighed in at just 27 oz (7.4" long). Danka is very small even for a Chihuahua! "Danka who isn't that keen on dog food only eats a small amount of dry food crushed up", Owner Kvetko said.
"Hercules", an English Mastiff with a 38" neck, is the current record holder at 282 lbs. His guardian John Flynn (who ain't so shabby himself at 270 lbs) says he once saw a bird roosting on Hercules' head. Hercules just sat there blinking, says Mr. Flynn. "He's not the smartest dog in the world, that's for sure."
Brandy", a Chihuahua from Florida, weighs 2 oz more than Danka but measures only 6" from the tip of her nose to the end of her tail. Now there's a dog who has a good reason to be afraid of the vacuum cleaner.
In 1989, an English Mastiff named "Zorba" tipped the scales—or should I say demolished the scales—at a whopping 343 lbs at the age of 8.
Try telling a 7 ft tall dog not to drool on the dinner table. "Gibson", a Harlequin Great Dane from Grass Valley, California, is 42.2 inches when standing on all fours, and when he's on his hind legs he's positively stratospheric. This dog is so tall he has to bend down to howl at the moon. He's so tall he doesn't drink out of the toilet; he drinks from the bidet. He's so tall he doesn't understand "heel". You have to say, "Skull!" He's so tall... ok I'll stop now
"Moose" weighed in at 286 lbs when he was named "largest dog in America" on Live with Regis & Kelly in Nov 2001. Moose's guardian Donna Vazquez considers that to be a low estimate because his butt wouldn't fit entirely on the scale.
