Hi. He is still young so do not stress too much. Get some yummy treats like roast chicken and sing his name, give him a treat, do this about 30 times until his ears prick up when you say his name. Now, go outside and start playing games with him. You can play this with the whole family. Armed with treats each of you has a turn to call him to you. Get down on your haunches, call his name, when he comes back to you grab his colar and give him a treat. Do this over and over again until he has got it then start playing hide and seek. Hide behind trees, call his name, when he comes to you grab his collar and give him a treat. When you go out with him call him back to you every 2 minutes and give him a treat. You do not have to give him a treat everytime. All the best.
