The roughly 3-feet wide-by-5-feet long-by-3-feet high (0.9-meter wide-by-1.5-meter long-by-0.9-feet high) doghouse has a sharp triangular shape, with a sloping shingled roof. It is made of Philippine mahogany and weighs about 250 pounds (113 kilograms).
"It's definitely in the master's hand," Oskar Munoz, assistant director of archives at the Frank Lloyd Wright Foundation, said of the design for the doghouse.
Munoz said Berger's is believed to be the only doghouse Wright designed. Wright likely sketched it out and then handed it to a draftsman in his studio who turned it into a working drawing, he said.
Wright was past 80 and likely busy with dozens of projects at the time, Munoz said, so for him to take the time to make the sketch was unusual. Wright died in Phoenix in 1959.
Berger, who now lives in the Sacramento area and has three rescue beagles, said he's not sure what he will do with the doghouse.
Although his beagles are worthy of it, he said they would probably prefer to stay in the house.
"My feeling is that I'd like it to go to a museum because it is a historical monument," he said.
