I hold my dogs on a short leash about 4 feet with my right hand streched to the side while left hand holds the handelbar. Fixed gear is essential for this activity !!!
I can ride with 2 dogs for a short distance only because the Jack Russell would pull me so hard I'm afraid she would eventualy die from exhaustion. Beagle is no problem at all, she loves running next to a bike.

:beer:
p.s. I would recomend reading a good book on dog behavior.
