Ouch! I'm so glad you weren't injured more seriously and are here to tell us about the crash! I'd call the ortho today and ask if you can be seen sooner. Tell them to at least call you if there are any cancellations.

And never mind whether or not there are leash laws in that county. A leash law would make it easier to go after the dog owners, but even without the laws I think you have some recourse through their insurance company. They were aware and admitted that their dog had been chasing bicycles, creating a dangerous situation for all of the riders and specifically for YOU. They need to be held accountable.
