The key to making Dragons tough is to put them in the air, take advantage of their 80ish foot movement and target wizards, Archers and Rogues first.
Keep the dragon in the air and take the OA's if necessary, but you should not take many. A wizard that casts shield or absorb elements, or a Rogue that uses uncanny dodge does't get opportunity attacks and that Ranger wielding a bow can only use an improvised weapon or a fist on his OA.
Another option is grapple, flight, drop/throw. Go bite the wizard, then grapple the wizard, then claw the wizard (or grapple again if the first failed) then fly into the air as much movement as you have left and drop. Alternatively skip the 2nd claw attack, grapple, then fly into the air and then throw the wizard at another party member. You can also do this against an archer, although in that case I would hang onto him until he dropped or stowed his bow.
If the party puts a combatant into flight to melee the dragon, climb straight up and after he closes use shove and knock him prone for very high damage from high altitude. Since your movement is more than his, he will typically have to dash to close with you and you will usually get the first attack after he closes. A dash by you takes you out of range of most spellcasters on the ground and into long range for most archers. With three attacks and a 20+ strength your chance of being sucessful is good, even against a high-strength fighter with athletics, you can also probably get a 4th shove if you ready one instead of dashing as you climb.
