Korda said in a statement on Instagram she was pulling out of the Aramco Team Series event at Centurion Club in Hemel Hempstead after being attacked last week.
"I regret to announce that I must withdraw from next week's Ladies European Tour tournament in London," Korda wrote.
"On Saturday in Seattle, I was bitten by a dog and need time to receive treatment and recover fully."
"I apologise to the LET, the sponsors and my fans for my absence. Thank you for your understanding and I look forward to returning to the course soon."
Korda provided no further details about the incident or the extent of her injuries.
The 25-year-old was in Washington last week for the Women's PGA Championship.
She had missed the cut for the event on the day prior to being bitten -- her third consecutive missed cut.
It is not clear when Korda expects to return to action, with next month's major the Evian Championship in France looming from July 11-14.
