I take my Chihuahua on my back rack in a cage but that is because he cannot keep up or be trained to keep up.
Trailers add tons of extra resistance to you. They are so heavy and those extra wheels. Hauling the ~100 lbs of trailer/dog is going to quickly kill your desire to cycle.
At 10 months old your dog has LOADS of energy and would benefit from running next to you.
You should get a bike leash if your serious about doing it frequently.

There are others, I just listed a few random ones from Amazon.
Virtually every municipality has leash laws so cycling while your dog is tethered to a leash is not the wisest thing you can do. Some cities have dog parks where a leash is optional but these are rare.
However, even if you live in a rural area you should still make sure that its a breed that can handle the pace. A better idea would be to run/jog with the dog where you have a much greater control than having him running lose or pull you into a crowd.
There are many energetic breeds to choose from that love to run especially in the sporting and working groups.
