Bruno suffered from gastric bloat, a condition where the stomach fills with air and twists. The Anaheim Police Department says fortunately Bruno was already at the hospital so he was rushed to surgery at 11 p.m. Tuesday.
Authorities said he was doing "remarkably well" on Wednesday. His handler R.J. Young was at his side when he got out of surgery.
In March, the 7-year-old German shepherd was shot in the face during a confrontation with an armed suspect.
The community has since rallied around Bruno. On Wednesday, students from Fairmont Private School in Anaheim presented a check for $2,200 to help an officer from the K9 unit and Bruno.
