Thanks everyone.
I feel so bad...I should have just waited until his normal vet was available...but I trusted the referral I got.
So...my blood is boiling...I just called the vet office, and the doctor wasn't available, so I spoke to a tech. She told me not to worry about it, because NO ONE EVER LOOKS AT THOSE INCISIONS ANYWAY. AHHHHH!!!!! So she thinks this is an aesthetic issue? Yes, his incision is nasty and the scar will be huge...but that is NOT the main issue here!!!!!!!!!!
So frustrating...I'm calling back later when the vet is in.
