Review on Quiet, Heavy-Duty Dog Nail Trimmer For Anxious And Sensitive Dogs: Precision Clippers For All Breeds And Sizes by Steven Emberling

I have used many clippers and I like these best. Having the file has made trimming curled under nails so much easier to do. You just pull the file out, put it under the curling nail and it files it down. Using clippers to get under a curl typically results in cutting into the quick and causing the nail to bleed. When this happens, the dog tends to become paranoid about getting its nails clipped.
