The boardwalk near the wolves is back open now that the pups "appear to be comfortable with zoo guests eager to catch a glimpse of them," the zoo said in a statement.
The four babies were born on May 13, 2019, to parents Siskiyou and Sequoia, who arrived at the zoo just over a year ago.
"Mom and dad have been amazing first-time parents," said Darren E. Minier, Assistant Director of Animal Care, Conservation, and Research.
Creating a pack is vital to the emotional health of wolves, who are shy, sensitive, and normally mate for life, Minier said.
He says the pups and their parents have a "forever home" at the Oakland Zoo.
