My dog does not eat on his own

My dog is a indian spitz and he's 2 years old, when we got him as a puppy he was too picky he would eat something one day and then not eat it again, so we started to feed him by hand but now i think this habit is not okay also we keep him accessible to food 24/7 so that he doesnt get hungry, is this the reason that he doesnt eat on his own? we also give him too much attention we are like always there for him 24/7 lol do you think thhat might be affecting his behaviour?
