My pup has had high anxiety levels while grooming since I cut too far 1 time. His black nails make it difficult for me to know how short I can safely go. This makes the whole process better in multiple way. His nails are smooth after trimming, we can easily do 1 paw at a time without him hiding in between and I can easily see and feel where his nails can be filed down.
I recommend these for people with nervous small breeds. Grooming is good again.
