When Aaron Jones walks Gozer, his Rottweiler-hound mix, people cross the street to avoid them. Mothers scoop up their children. A lost motorist once rolled up the windows and drove off after spotting the dog. One woman screamed.

“He’s the nicest dog I know,” said Jones, 33, of Oakland, Calif. “It’s hard to understand all the fear.”

Gozer isn’t aggressive and doesn’t look mean or bark, Jones insists — people are afraid of the dog purely because it’s big and black. As a puppy, Gozer was passed over for at least a month before Jones took him home.

According to animal shelter officials, big, black dogs like Gozer have more trouble finding a happy home than do other dogs. Some shelters even have a name for it: “Big black dog syndrome.”

…At the city animal shelter in Rogers, Ark., big, black dogs almost always make up the bulk of the animals put to sleep each month. Last month, 13 of the 14 dogs killed by the city were large and black — mostly Labs, shepherd mixes, pit bull mixes and Rottweillers, said Rhonda Dibasilio, manager of the city Animal Services Department.
