The children were bitten by the dogs as they played in Scarborough Square Park Friday, The (Norfolk) Virginian-Pilot reported.
An adult was hurt as they tried to fend off the animals and the dogs' caregiver was also bitten, said Detective Tonya Borman, a police spokeswoman.
For one of the children, 9-year-old Michael Jones, it was the second attack within weeks, the newspaper said.
"This is the second time this has happened in six weeks," said the boy's mother, Tara Matthews. "The first bite should've been the last bite."
The other two children were 7-year-old son Jamari Love and his sister, Da'Shawna Bailey, 12.
Jamari required plastic surgery and required more than 100 stitches to close his wounds.
"I don't want any more kids to be hurt," said Markivia Bailey, the children's mother. "It's spring break, and I don't see any kids outside."
The number of dogs involved in the attack was not reported. The dogs' owner could not be reached for comment.
