Gary post some pics showing the nails your talking about please. I am curious as mine all have the equvalant of bear claws lol as i can testify from the state of my kitchen hardwood. The only time I have seen "nubby" nails is if the dog has spent a lot of time on my concrete pads, then the nails become like what you describe, wear off very short and dont touch ground, happens during the summer here as I put them in the outside runs on rotation but in the winter with the snow they grow them back. So i wonder if the pics are of dogs kept on concrete ? JMHO but my thoughts have always been the nails on a neo is the hardest aspect of grooming, not bathing, since the nails are so difficult to keep nice, almost wish I had farriar tools when cutting them
