Miranda...so sorry to hear about your crash. A few years ago my season ended on Labor Day because of a crash where I fratured my shoulder. I put my mtn bike on the trainer because it was easier to get on and off and pedeled sitting upright because my arm was in a sling. It mentally felt good to keep my legs spinning.
I think that was a horrilbe attitude of the dog owner. Something needs to be done, not just for you and your future and what you will intail during recovery, but for any other cyclist that rides past their house.
BTW...I often thought if keeping my shoulder mobile would have been better because PT was so painful as my shoulder was stuck and I still do not have full range of motion. Then again it might be different with a collarbone than a shoulder.
as you have heard from others, take time to heal
