Walkers surgery (scrotal ablation)

hi my name is marissa! walker is my 2.5 year old french bulldog. he recently got neutered and had complications after surgery. we’ve taken him to the emergency vet 2 times in less then a week. he was admitted to piper memorial hospital for a scrotum ablation surgery. the doctor has never seen this extreme of a case. his scrotum was leaking with puss and blood and as big as tennis balls. we don’t have answers as to why this happened or what exactly it was at this current time. our main priority is getting him healthy. funds will be used to pay for his emergency surgery and stay. i knew something was wrong from the start but our vet reassured me he was okay and the next thing i knew we were being rushed to the hospital. we appreciate anything. thank you.
