Herb Wells of Alpaugh CA takes the most amazing photos of coursing dogs I have ever seen- probably that anyone has.
A couple of sets here. The first three pics demonstrate the incredible and totally normal hyperextension and flexing of a running dog’s first joints (third is also one of out own breeding, Daniela’s Shunkar). This is also why you should not remove dewclaws.
Second batch: synchronized dogging. Is this common?!
