Bella had a spur growing out from her heel, left paw. She isn't taking care of it herself. A month ago the vet trimmed it back. I'm worried it'll get caught in the bars where she does her begging going up and down. In the event it starts bleeding, what do you use? What do you do? I don't dare trim it with this squirmy pig, no way to do it alone anyway. And I can't go to the vet every month. TIA
