Dragging leg

When Rex get tired his rear right leg starts dragging a little. This wears on his toes and nails. Now with the colder weather the ground is harder and the wear on his feet causes one of his nails to bleed. A doggy boot prevent this.

Rex is still not showing any sign of pain. He still walks about a mile on his morning walks. On the 27th he will be 12, such trooper this guy.
