So sorry to hear about Bronco
I wish her a speedy recovery.
Friends of ours had a boxer that broke her leg, severely. Needed major surgery, plates, etc. They are a VERY active family that go on long hikes and took her on 10-12 km runs regularly. Her recovery period was lengthy, but she's back out there with them again. I went on a 3 hr walk with them not too long ago and she did fantastic. Being healthy and in good shape helps I think.
