My 50D has a sports mode on the dial but also has a menu to set the Autofocus mode: One Shot, AI Servo (for moving objects) and AI Focus that automatically switches between the two.
I'd be surprised if you don't have something similar and it's really helpful when shooting dogs.
My DSLR doesn't have preset modes, but afaik the modes only control aperture and shutter speed - focusing is a separate setting.
EDIT - here you go
Half way down this tells you how to select between the various AF modes. Assume you'd need AF-C.
This is from the bottom of that page;
For most sports, you can just shoot at the D90's defaults.
If I was shooting sports all day with the D90, I would force the AF Mode to AF-C (use the top switch), which will always track motion. The default AF-A mode will figure it out for itself, unless the players are standing still when you first start to hold the shutter to compose.
If you prefer to tell the D90 on which player to focus, use MENU > Custom Setting Menu > a Autofocus > a1 AF-area mode and select 3D-tracking. Now the D90 will focus where you tell it, and as your selected player runs around, the D90 not only will track him as he gets nearer and farther, the D90 will track him as he runs around from left to right inside the frame!
