I recently taught June to fetch and now both of mine fetch.
Here is what I did:
June wasn't interested in her toys at first, so I got a small one with a squeaker and teased her with it. She liked it that the toy squeaked and I would really just tease her with it until she gets excited.
When she was used to her toys and playing with them on her own, I sat on the ground, squeaked the toy and threw it. She would go over to it and pick it up. I showed her the treat that I had in my hand and she came over.
Sometimes she would drop the toy and not get the treat, but she caught on really quickly. Now, she loves to play fetch.
She doesn't compete with Cash yet. Cash is way too good at fetch for little June to keep up.
I hope this helps. Good luck.

Ps. If he isn't interested in the toy at first, and you don't have another dog that likes toys, get someone in the household to play with you with the toy. If the doggie then sees that this is how he should play, he will try to play with you.
