Ma'am can I give deworming syrup to my puppy, if yes , suggest me some ?

I am looking for leash training and socialisation options for my pup. He's been trained and he follows all commands without distractions at home but it's difficult for me to take him out because he reacts to all stimuli outside and tries to run towards them making it difficult for me to manage him. He's very friendly, but hyper active around people and outside. Could you please suggest good training options that would help me with this?
