First, make sure you have the necessary things to raise your Dragon. The basics needed will be the Medical Station, a nest, and space in your cave for your Dragon. Item-wise, you will need Dragon Food, and most likely you will need to use medicine at some point. If you have a Freebie, a nest and food is not really needed.
If your Dragon is still maturing, I highly recommend to always keep around a piece of Dragon Food or two at all times, and a bottle of medicine if you cannot check on your Dragon regularly.
After your Dragon has finished maturing (or after you get your Freebie), you'll want to figure out what its favorite activities are to max its happiness percentage. Things it loves to do will raise it by 10%, Likes will raise it by 5%, Neutral does not raise or lower its percentage, Dislikes lower it by 20%, and Hates will lower it by 30%.
Your first activity you pick for your Dragon is technically impossible to determine wether it will like it or not, so you might want to make sure you have a bottle of medicine just incase while doing this. I like to personally try all activities at least once, just to get the "???"s out of the way. However, I recommend to always have your dragon at at least 11% happiness, or 31%, before choosing an unknown activity, as if it gets to 0%, your Dragon will be diagnosed with depression and will need a bottle of medicine to recover. When it does recover, it will only have 1% happiness.
I hope this has helped anyone who is new to raising dragons.
