Riley's toe ended up needing surgery. I really wish we had done it sooner. Oh well. Our vet put a suture inside the toe. It basically pulls the toe in tight since the ligament that used to be there is torn and it makes the tissues angry so as to stimulate lots of scar tissue. Hopefully we'll get a tight, tough toe from it.
So Riley is to be leash walked only for the next 6 weeks and then we will rehab once again. Hopefully this is the very last injury.
