post-neuter???

Kodiak was neutered 5 days ago, everything waent well not much swelling afterwards no soreness. Last night i noticed the skin around the incision has turned black and seems to have spread farther this morining is this normal?? I am going to call my vet, but they don't open till 11 this morning.his incision is closed with surgical glue and it is still closed. has anyone seen this before?

I haven't, I'd definitely be back in the vet's office.

That doesn't sound good! Did you get him to a vet?

Sounds like an infection, was he put on antibiotics?
