My pup Cooper

Hi everyone, I live in Australia and have a 7month old male Cooper. I have never owned a JRT before. I did my research into the breed and he suits me perfectly. So full of love and he has a great personality. I love him so much. My question is, He likes to lick everything and by everything I mean everything. Is that a normal trait of a JRT? He also loves people and meeting new people, but he is a bit a jumper and gets crazy excited, I’ve tried to get him to stop doing it but he still does. Is that normal for a pup? Also his recall is not the best because he gets so excited on walks as he smells everything and has to wee on every plant bush and tree. He has not been nurtured. Thanks I’m advance.
