I think Willa has a corn on her front left foot. I don't see a distinct border yet but there are some telltale signs, like limping on rough surfaces and a hard-feeling spot in the pad. Miss Jan graciously sent us a boot to try and I've joined the Greyhounds with Corns FB group. We're doing Bag Balm and colloidal silver. I'm just wondering if anyone has ever had a greyhound with a corn that resolved and never came back, or it's always a lifelong affliction. (Give me some hope, people! )
