Just haul him to the vet it will only cost a 100 bucks.... My buddy's bulldog got cut pretty bad and the vet fixed him up and it was real cheap...
I'd like to have that vet near my house. My bulldog got in my hog pen with two big boars early one morning and got cut up more than I felt comfortable to try and doctor. It cost about 430 bucks. Even though he was free he is now my most expensive dog in my yard lol.
