You can upgrade your dragon's tier by going to the Dragon Spire on the City View Map, tap on the dragon you want to upgrade, tap on the Tier icon, equip the needed Relics and tap Evolve. 

Level

Increasing your Level improves your base Army Strength. Makes your march more powerful in combat. Increase your Level from the Dragon Spire on the City View Map. Tap on the dragon you want to level up, use the Chow sliders to feed your dragon Chow (dragon food) you own, tap the Arrow button!

Rank

Increasing your Rank improves your dragon's abilities. 
Abilities can range anywhere from improving your troop training speed to making it easier for your troops to kill certain monsters in the game. The higher the Rank the more powerful the effects of the abilities. Increase your Rank by collecting dragon specific Shards. Once you have enough Shards, go to the Dragon Spire on the City View Map. Tap on the dragon you want to rank up and tap on the arrow pointing up. You can see how many Shards you need to Rank up your dragon to the next rank there.
