Does she have any puncture wounds? those are more likely to get infected, so keep a close eye on them. It would be good if you posted a photo of her wound, so we can suggest appropriate care. In general you can wash out wounds with saline solution. Peroxide burns injured & healthy skin, so I don't recommend that. Then I would apply Neosporin ointment (NO CAINE product). Mainly keep her away from others as chickens will peck a wound and make it much worse, it can also bring out their cannibalistic tendencies.
For a bird that appears to be in shock put her in a quiet, warm, darkened place. Do not attempt to feed or water until she is acting more herself. Chickens generally have great recuperative powers IF they don't get infected.
I don't know what practices you will put into effect to prevent your dogs from ever harming another chicken. But, I like to tell folks that dogs and chickens should NEVER meet. You never hear of a chicken killing a dog but, dogs (and cats) certainly enjoy "playing" with them and the chicken is the one that ends up dead.
