John - I'll do my part. I head to back to Surrey regularly, and will keep an eye out. I hope Kate returns to full strength.

I; ve seen this many times, once or twice with my now own gone dogs.
Often a pair or pack of get along dogs or siblings will suddenly gang up if one gets exited or challenged and then the hyper action starts, hard to stop or control, Its also a mentality and common pattern found in modern humans. Glad you walked away with minimal damage.
