I'd like to add Gina, that on the day the vet arrived she had no heat in her feet and did not respond to the hoof testers either. Mind you her hooves are solid as a rock and 1/2 inch thick. The vet proceeded to carve a piece of her sole away and then did the hoof test on her -wish there were explatives on this site to show emotion!!! She did have a very faint digital pulse though. -There were very few obvious signs except stretched white line - which came after she had develped small fat pads, until it was full blown founder. michelle o
