Can you tow a Chevy blazer 1990 S10 4x4 with a dolly?

The S10 Blazer has a "double disconnect" 4wd system. It is disconnected at the transfercase and at the front differential. It is ok to tow it by the front of rear wheels with a Dolly and will not do any damage if not done for long distances. But remember, with any dolly towing there is a risk of damage.
