We’ve rescued an ~1-year old flat-coated retriever. He’s amazing with nail trims and I’ve just now tonight for the first time slowly shaved away at them with my miller’s forge trimmers but his nails don’t look like those on my previous rescues. Do I need to keep trimming these to get the qwick to recede or what am I seeing? Why aren’t the nails solid on the bottom? Have they been trimmed too short? Are these considered split? Does he need vet treatment?
