Play with a puppy they are small and too cute all dogs want to play and have fun when they are puppy's also a great dog is a Black lab or a German Rottweiler they are both great dogs also it would help if we knew why you are scared of dogs
I recommend not listening to anyone else saying: "Play with one! Buy one!". No. Suddenly introducing yourself to a great fear can result in violent interactions. Don't tell me you can control yourself! That's exactly what stranded people on an island would say, and next thing you know-BAM-you've become a cannibal. What could work is taking counseling, then asking your counselor, after multiple sessions, whether or not you're ready to face your fears. Don't force something you cannot bring yourself to do.
