Sex does not only happen in the gonads but also in the head. A neutered dog can have an erection and that is quite normal. It is not bad for him as long as it goes away before drying out the penis. If you suspect that the penis cannot be withdrawn into the sheath, then I suggest you put vaseline on it to keep it from drying out and take your dog to a vet or Pet ER.
